    1500 PSI [100 Bar]

     

    ur.jpg

    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.

  • PH

    Piston Seals

    Nitrile/Nylon

    -20/220F [-29/104C]

    3000 PSI [205 Bar]

    ur.jpg

    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.

  • PR

    Piston Seals

    Neo-Fabric/Polyacetal

    -22/212F [-30/100C]

    7250 PSI [500 Bar]

     

    ur.jpg

    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]

     

    ur.jpg

    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

     

    ur.jpg

    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]

    ur.jpg

    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]

    ur.jpg

    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]

    ur.jpg

    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]

     

    ur.jpg

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

  • P2G

    Piston Seals

    Nylon/Nitrile (Step Cut)

    -22/230F [-30/110C]

    11 600 PSI [800 Bar]

    ur.jpg

    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]

    ur.jpg

    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]

    ur.jpg

    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]

     

    ur.jpg

    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.
