Technical data
Bonded seals are a combination of a metal washer and an elastomer lip bonded to the metal element by vulcanization.
The metal washer (in galvanized steel or stainless steel) ensures that the connection components are securely fastened. The thickness of the washer limits the compression of the elastomer lip (NBR or FKM/Viton®) and thus prevents the seal from being over-tightened, thus ensuring tightness. The internal pressure increases the sealing force by activating the sealing lip. Bonded seals are available in two different formats, standard and self-centralizing.
METALLIC PART
| Bonded Seal | Profile | Metal part | Minimum pressure | Application |
| Standard |  | Galvanized Steel AISI1008-10101 | 540 MN/m2 | General |
| Self-centralizing |  | Galvanized Steel AISI1008-10101 | 540 MN/m2 | General |
| Standard | | Stainless Steel SS316L/SS304L | 540 MN/m2 | Corrosion protection under extreme conditions |
| Self-centralizing | | Stainless Steel SS316L/SS304L | 540 MN/m2 | Corrosion protection under extreme conditions |
ELASTOMERIC PART
| Elastomeric material | Polymer class | Resistant to | Agressive to |
| NBR | Acrylonitrile-Butadiene, Buna N | Oils, greases, hydraulic fluids, chemicals, a wide variety of hydrocarbons, etc. | Ozone, ketones, esters, aldehydes, aldehydes, chlorinated and nitro hydrocarbons |
| FKM/VITON® | Fluorocarbon Rubber | Better resistance to fluids than other elastomers. In addition to all aliphatic, aromatic and halogenated hydrocarbons, acids, animal and vegetable oils. | Ketones, alcohols and ethers with low molecular weight and nitrogen compounds |
