Water is a limited asset, one of the most important resources we have and which we need to manage and take care of accordingly.
We use large amounts of water for domestic purposes every day – for drinking, showering, flushing, cooking, mopping…. Indeed, according to the INE (National Institute of Statistics), the consumption of water in Spanish homes is 132 litres per person per day.
Moreover, water is also vital for industry (as an ingredient for the product to be manufactured and as part of the production process) and for agriculture (irrigation) too.
Whatever the use, we at JIOrings help companies (desalination plants, water suppliers, drinking water treatment plants, irrigation firms…) to achieve optimum watertightness in water piping to ensure there are no leaks. The watertight properties of our O-Rings designed for water piping valves and accessories ensure that not a single drop is wasted.
To this end, we analyse each company´s needs and supply the ideal O-Ring for each use. The size, cross-section, hardness and material of the product, in addition to the required approvals, will vary in accordance with the needs of each individual customer. All our years of experience enable us to meet the needs of water suppliers through the annual programming of their most common measurements. Furthermore, to manufacture and supply special sized seals.
We also market the star mix for the sector related to the supply and treatment of water: LPM534 EDPM FDA for DRINKING WATER.
O-Rings installed in valves, pumps, piping and similar applications should be resistant to the fluid itself without the need to add any ingredient or alter the essential characteristics of the product being conveyed, such as the colour, smell or flavour.
This mix, approved by the German Environmental Agency (Umwelt Bundesamt, UBA), complies with all the hygiene and toxicology requirements established by this agency and those of European Regulation CE/1935/2004.
We at JIOrings adapt to each of our customer´s requirements and the standard in relation to O-Rings in each country. We always attach the corresponding certificate attesting to our compliance, thereby guaranteeing the suitability of our O-Rings for each specific purpose.
What about you, what seals do you need?
¿Sabías que hay juntas tóricas capaces de detectar el metal?
El uso de las juntas tóricas en las industrias alimentarias y farmacéuticas es muy habitual. La mayoría de los equipos convencionales de detección de metales son capaces de revelar inmediatamente dicha alerta de contaminación.
A diferencia de otras industrias donde el material de la junta o su resistencia a altas temperaturas puede ser la propiedad clave a la hora de seleccionarlas, en las aplicaciones farmacéuticas y alimentarias la clave es la seguridad.
En JIOrings garantizamos la seguridad del producto y el cumplimiento de las normativas FDA, proporcionando a nuestros clientes una gama de juntas tóricas detectoras de metal (o capaces de detectar el metal), que han demostrado ser la solución más rentable y segura para garantizar su uso en aplicaciones alimentarias y farmacéuticas.

You won’t find more materials available anywhere else!
Whereas in the previous post we talked about the importance (or not) of size, this time we are going to talk about the relevance of a specific size. If you are asking yourself why, then just keep reading.
The JIOrings warehouses hold a stock of more than 30 million O-rings of different inside diameters, cross-sections, hardness, materials, approvals, colours… And only the client knows the real working conditions to which the seals will be subjected and the properties that need to be complied with.
Without wishing to be exhaustive, we would like to emphasise the importance of choosing the right o-ring. The use of seals is universal and you will see them in both static and dynamic applications, on the interior and exterior of machinery parts and in a wide range of sectors. Of course, the same seals are not used in the healthcare sector, where O-rings need to be resistant to fluid, inert, and not produce substances or alter the essential characteristics of the product, as the seals used in the hydraulic sector, where resistance to extrusion and oils is more important.
There is a specific size (4.47 x 1.78) that due to its consumption in different sectors (food, pharmaceutical, medicine, biotechnology, chemical, petrochemical, gas, aeronautics, electronics…), we have managed to create a huge stock of different materials and approvals.

Basic information on the materials used
NBR Acrylonitrile butadiene rubber (NBR) is the most widely used material in O-rings due to its excellent mechanical properties, resistance to abrasion, low permeability to gases and high resistance to mineral oils and greases. [ NBR O-Rings]
EPDM Ethylene Propylene Diene Rubber or EPDM is an elastomer thermopolymer that provides good resistance to abrasion and wear for O-rings. [ EPDM O-Rings]
VMQ The term silicone includes a large group of materials of which VMQ (vinyl-methyl-silicone) is one. Silicone elastomers have may useful properties, the most noteworthy of which are good heat resistance and low-temperature flexibility. There are also highly resistant to ozone and the passage of time, in addition to having good insulating and physiologically neutral properties. [ VMQ O-Rings]
FPM-Viton® O-Rings FPM is a fluoroelastomer obtained from the derivation of synthetic rubber and elastomer fluoropolymer. O-rings manufactured from this material provide greater elasticity and resistance than other types of rubber, in addition to possessing high resistance to highly aggressive fluids, good resistance to deformation, excellent sealing force retention and the original hardness of the design. [ FPM-Viton® O-Rings]
FFKM Evolast® Perfluoroelastomer-made (FFKM Evolast®) O-rings are designed to combine the needs of chemical and thermal resistance provided by the PTFE and the sealing properties typical of elastomers. One of the advantages of seals made with FFKM is the wide range of temperatures they are capable of withstanding. [ FFKM Evolast® O-Rings]
Treatments that improve the performance of O-Rings
Sometimes standard elastomer O-Rings need to be treated with specialised surface treatments. By doing this, the equipment’s performance, assembly and installation is improved.
At JIOrings we can treat the O-Rings surface with specialised processes such as cleaning, chemical immersion or coating, with the aim of reducing friction and adhesion, to achieve a permanent lubricating effect or to facilitate the installation of the gaskets.
These treatments are usually done for large quantities or batches anyway, in case you need this type of treatment, we recommend that you contact us so we can analyse your needs and offer you the appropriate solution. These are the different treatments or surface coatings that we offer:
• Coloured PTFE
• Micro Talc
*Download of the technical specifications for each treatment, is subject to the purchase of gaskets treated to any of the aforementioned coatings.
PTFE (Polytetrafluoroethylene coating), also known as TEFLON® (trademark of Chemours), is a coating based on fluoropolymers that provides high anti-adhesion to gaskets.
PTFE is a material suitable for contact with food (FDA), so it has many industrial applications such as the food, beverage, chemical and textile sectors etc… The process for coating gaskets with Teflon® PTFE consists of four different parts:
• Degreasing – Consists of eliminating any organic or inorganic residue that the pieces may have. For this, degreaser is applied to the gaskets.
• Sandblasting – Or preparing the surface to be coated to guarantee maximum adhesion of the Teflon® by blasting with aluminium oxide.
• Application – This is done with liquid spray guns, electrostatically, HVLP or with powder guns. This process may consist of several layers of product, depending on the purpose of the coating.
• Curing – For Teflon® to maintain its properties, the coating must be polymerised. Which means heating the gaskets to 360°C and maintaining this for 10 minutes.
The silicone or siliconised coating provides the gaskets with greater anti-adhesion, waterproofing and mechanical resistance. In addition, silicone gaskets also have better sealing and thermal insulation. A silicone gasket has the following advantages:
• Better thermal resistance.
• Good inflammability properties.
• Excellent impermeability (even in hostile conditions: outdoors, water, steam, smoke and combustible gases).
• Good flexibility.
• Can be cleaned easily.
• Increased durability.
Molykote is Dow Corning’s commercial name for their specialised lubricants. This lubricant was developed to solve industrial lubrication problems, and in turn to reduce friction and wear.
By treating the O-Rings with Molykote, which incorporates molybdenum disulphide (MoS2) into the lubricant, it is possible to create a final product capable of withstanding high loads, high and low working temperatures, dirt and dust, aggressive chemical environments and extreme speeds.
The MoS2 is incorporated into the elastomer in the form of a dry lubricating film dispersed over the sealing surface. This produces a mechanical interlacing, which in the long term, reduces the friction and wear caused by dynamic stresses. The main advantages of this type of treatment are:
• Improved separation in automatic assembly.
• Reduced friction and dynamic tension.
• Pollution containment.
• Protection against corrosion.
• Dispelled heat.
• Power transmission.
• This process is suitable for all types of elastomers.
When this static lubricant is applied to O-Rings, it allows for their use in advanced applications that require high electrical conduction, heat transfer, vacuum sealing and/or stability of a join.
It is often necessary to improve the coefficient of the O-Rings friction, since they have rough and adherent surfaces. In these cases, surface treatments such as talc can be applied. Thanks to this method, a reduction in friction can be achieved, both to facilitate assembly and to prolong service life.
Talc treatment, consists of applying it to the gaskets in a drum as a coating of disseminated dust. In this case, no interlacing occurs with the surface of the elastomer.
The talcum powder particles create an impermeable barrier that reduces the penetration of air and liquids into the gaskets. The more laminar the talc, the greater the barrier effect it will have. These are the main advantages of a talc-based treatment:
• Disseminated powder coating.
• It prevents the components from sticking once packaged.
• It is not suitable for dynamic applications.
• This process is suitable for all types of elastomers.
Do you need seals with specialised homologations?
On more than one occasion we have commented on the importance of the choice of O-Ring seal. O-Rings are suitable for both dynamic and static applications but their success will depend on the properties of the gasket and the design of the housing.
The correct measurement, material, hardness, the temperature it will be subjected to, and the conditions in which it will be sealing. All these parameters have to be taken into account when selecting the gasket. Don’t forget that the O-Ring must comply with the special homologations that certify its suitability to come into contact with drinking water, food, beverages, medicines, fire, gas etc.
JIOrings O-Rings application is wide and varied, and is commonly used in food, health, automotive, aeronautics and oil sectors etc. but these gaskets are also present in many home appliances available at our fingertips.
Whatever the final destination, our goal is that the seals treatments always comply with health requirements, drinkability and safety required in each case by each client. That is why we have been working for years to have seals materials certified by entities and independent laboratories.
In this table you can check which mixtures comply with international homologations, and the origin of the country that issues them.
