| Piston |  | TPU | 92 SH A | ≤400 | -35 °C to +110 °C | ≤0,50 m/s |
Quick LINKS
Piston U-rings
Piston U-Rings have a higher inner lip than the outer lip and are generally used in single-acting applications. Their asymetrical lips design provides a continuous contact with the bore. Their special relief grooves and extrusion resistance thanks to the back-up ring ensure high performance and long service life.
ADVANTAGES
- Superior static and dynamic sealing effect
- Simple groove design
- Easy assembly into closed grooves
- Dynamic pressure relief grooves
- Very good wear resistance
APPLICATIONS
Heavy-duty cylinders, scrap cutters, hydraulic jacks.

INSTALLATION
Easily assembled into closed grooves. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.
| Maximum permissible gap TPU | |
Pressure (Bares) | S Max (mm) |
100 | 1,00 |
150 | 0,80 |
250 | 0,70 |
400 | 0,60 |
Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers
