  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

  Retainer Rings Polyacetal -40/230F [-40/110C]

  KR ,These split rings made of Acetal material are primarily used as retaining devices when used in conjunction with PR-style piston seals. 

• 

  PZ

  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

• 

  P1B

  Piston Seals Nitrile/Steel -22/212F [-30/100C] 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.

• 

  P1B-1

  Piston Seals Nitrile/Steel -22/212F [-30/100C] 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.

• 

  P2B

  Piston seals BR.PTFE/Nitrile -30/230F [-34/110C] 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

  Back-up Rings Nylon -40/250F [-40/121C]

  ST/N profile Nylon back-up rings are primarily used as anti-extrusion devices to be used along side two-piece P2B-type seals. 

• 

  P2B/U

  Piston Seals Polyurethane/Nitrile -22/212F [-30/100C] 5800 PSI [400 Bar]

  Similar to the P2E-style, the P2B/U-style uses the aid of two compact sealing edge. This bi-directional piston seal offers perfect fluid control, constant preload as well as reduced friction and wear.

• 

  P2E

  Piston Seals Polyurethane/Nitrile -22/212F [-30/100C] 5800 PSI [400 Bar]

  This two-piece assembly has a tough polyurethane outside sealing ring offering both stability and extru-sion resistance. An elastomeric expander ring offers constant preload to insure good low-pressure sealing ability.

• 

  P2G

  Piston Seals Nylon/Nitrile (Step Cut) -22/230F [-30/110C] 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.

• 

  P3C

  Piston Seals Neo-Fabric/Acetal -22/212F [-30/100C] 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.

• 

  P4A

  Piston Seals PTFE/Nitrile/Nylon -40/250F [-40/121C] 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.

• 

  P5B

  Piston Seals Nitrile/Polyamide/Polyester -22/212F [-30/100C] 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.
