5800 PSI [400 Bar]
PB profile is a non-symmetrical hydraulic piston type U-Cup. Being Uni-directional in design, two PB seals must be used , back-to-back , in separate grooves to provide bi-directional pressure sealing.
Nitrile NBR 90A
1500 PSI [100 Bar]
PB/N profile is a single-acting piston seal with an asymmetrical designed manufactured in homogeneous rubber material. It is particularly well suited for pneumatic or low pressure (˂1500 psi/100bar) hydraulic applications. Two PB/N seals can be used, back to back, in separate grooves to provide bi-directional sealing.
3000 PSI [205 Bar]
PH profile is a single-acting piston seals using a Nitrile (NBR) sealing lip for excellent sealability mated to a fitted reinforced nylon anti-extrusion ring.
7250 PSI [500 Bar]
PR profile is a single acting piston seal, suitable for medium duty application; seal set consists of two elements: a) Acetal anti-extrusion wear ring. b) high specification NBR 80 shore and NBR impregnated cotton sealing element
KR ,These split rings made of Acetal material are primarily used as retaining devices when used in conjunction with PR-style piston seals.
Cast or ductile iron
PZ SAE 660 split piston rings for high shock/high load applications, commonly used in conjunction with PH-style piston seals
174 PSI [12 Bar]
P1B profile is a complete pneumatic piston with a double cup seal and a vulcanized metal disc support. It is fixed to the piston rod with a lock nut to avoid loosening during service.
580 PSI [40 Bar]
P1B-1 is of similar design to the P1B-series but with added axial length for increased pressure resistance and better stability.
5800 PSI [400 Bar]
P2B Seals are two-part sealing units combining a low-friction, PTFE-based dynamic sealing element and an elastomeric loader ring insuring a fully energized device for both low and high pressure applications.
ST/N profile Nylon back-up rings are primarily used as anti-extrusion devices to be used along side two-piece P2B-type seals.
Nylon/Nitrile (Step Cut)
11 600 PSI [800 Bar]
P2G profile is a high pressure, two-part seal set, consisting of a stepped-cut Nylon sealing ring and an elastomeric loader ring for producing pre-load.
6000 PSI [414 Bar]
P3C double-acting piston seal is a heavy-duty seal assembly used for split pistons. The center portion of the seal is manufactured from fabric-reinforced Nitrile, and an Acetal L-Shaped bearing ring is located at either end to protect from extrusion damage.
6500 PSI [440 Bar]
P4A is a bi-directional, piston seal for heavy duty applications. The PTFE cap and custom elastomer ring provide a low friction seal with excellent leakage control. The anti-extrusion rings allow for larger than normal piston clearances.
5800 PSI [414 Bar]
P5B seals are designed for easy installation on one-piece pistons. Using a homogeneous center ring for excellent sealability, split nylon rings are added for extrusion resistance as well as split bearing rings for guiding.
P5B-1 Similar to the P5B design, these seals have a heavier footprint to serve in a more heavy-duty environment.
