  • MFP Seals X-PAC® U-Cup
    MFP Seals X-PAC® U-Cups have N6014 X-Ring Expander & Knife Trimmed Sealing Lip. Molded Urethane styles: XP Std & B-Lip; XPR, Twin-Lip; XPAR Anti-Ext Ring; XPRA, Twin-Lip w/Anti-Ext Ring; & XPYS Y-Ring U-Cup & Secondary Lip Base. Other compounds available....

  • X-PAC® Loaded-Lip, Symmetrical & Asymmetrical U-Cups

    X-PAC® U-Cups are a very versatile reciprocating seal design.  The rubber expander creates a compression style seal, while still operating as a pressure actuated U-Cup.  The result is better low-pressure sealing and less startup leakage.  The primary function of a B-Lip X-PAC® is for linear rod applications. However, they can also be used for piston applications when straight lip tooling is not available. MFP Seals’ X-PAC® U-Cups feature a knife trimmed sealing lip for increased sealability.

    Contact MFP Seals for more information on X-PAC® and our other sealing products.

  • MFP Seals - BRU Rod Buffer Seal
    MFP Seals BRU, compact, dual-purpose rod & buffer seal handles most of the sealing load while relief vents eliminate pressure traps allowing fluid bypass to energize the primary rod seal, providing unparalleled performance. Also available with an AE-Ring....

  • BRU - Rod Buffer Seal 

    MFP Seals’ BRU is a compact, dual-purpose seal.  Designed to be both a rod and buffer seal.  The BRU handles most of the rod sealing load while special relief vents, designed into the seal, eliminate pressure traps between the BRU and primary rod seal.  This allows fluid to bypass the BRU, energizing the primary rod seal.  Working in tandem, the BRU and primary rod seal provide unparalleled performance in extreme applications. 

    Available in both Inch (BRU) and Metric (MBRU) sizes, this seal is available in U2150, U2151, and U4150 Urethane compounds. This seal offers extremely low compression set and excellent extrusion resistance. Working together with the primary rod seal, the rod buffer enhances performance in extreme applications. *The addition of an M1001 Anti-Extrusion Ring will significantly increase the seal’s extrusion resistance and pressure rating.
