SIL seals
SIL seals are polyurethane U-cup seals made from ether-based TPU. They feature a double-lip design with a secondary dynamic sealing lip. These seals provide good resistance to hydrolysis (moisture attack) and good low-temperature resistance. SIL profiles are suitable for pressures up to 350 bar (5 075 psi) in light- to medium-duty applications and are available in metric sizes. Some fit seal housings in accordance with ISO 5597:2010.
