SKF/North America Piston Seals Incorporating Anti-Extrusion Rings

These SKF piston seals incorporate patented locking anti-extrusion rings made of polyamide (PA). They are split for easy installation. Their snap-in design makes it easy to identify the correct installation direction, holds them in place when installed and prevents damage during assembly. Piston seals incorporating anti-extrusion rings have an improved high pressure performance and minimize the risk of gap extrusion at abrupt pressure peaks. LCP Profiles LCP profiles have a PTFE slide ring supported by harder PA anti-extrusion rings and a T-shaped nitrile rubber (NBR) energizer. These capped T-seals are suitable for pressures up to 690 bar (10 000 psi) and available in metric and inch sizes. Some metric sizes fit seal housings in accordance with ISO 5597:2010. For additional information, refer to LCP profile data. LTP Profiles LTP profiles have a nitrile rubber (NBR) sealing ring supported by harder PA antiextrusion rings on both sides. These T-seals are suitable for pressures up to 345 bar(5 000 psi) in medium to heavy duty applications and are available in inch sizes where O-ring dash-number housings are used.
