Provided as part of a seal assembly to prevent seal-extrusion. Back-up rings are generally used with system pressures of approximately 1,150 PSI (8 MPa) to 10,000 PSI (69 MPa).
Elastomer seal for static applications. Q-Rings have O-Rings that have increased resistance to rolling in the gland compared to O-Rings.
PolyMod® low friction O-Rings, recommended for applications requiring low stiction and/or friction, are available in all materials except silicone and fluorosilicone.
Elastomeric square ring for direct contact static seals and cap energizers. These seals have high sealing efficiency and shape stability.
Single acting sealing element comprising a PolyFluor™ U-shaped ring and a metal spring energizer. It has highly specific surface pressure which provides for very good sealing action.
