Factory Directly Supply static sealing AS568 rubber o rings and Backup rings

PTFE backup rings are used for static and dynamic applications. It's better used for static sealing applications with corresponding O-ring.

The use of PTFE backup ring will help control O-ring extrusion in high pressure applictions. PTFE backup rings are compatible with all hydraulic fluids,since they are virtually chemically inert,and also can be used in applications involving elevated operating temperature conditions.In addition,PTFE backup rings can greatly improve O-ring performance and extend service life, even if extrusion does not present a problem.

(PTFE) Backup Rings (VIRGIN PTFE 55 SHORE D) also available.

We also offer a large selection of PTFE Backup Rings including; Solid (uncut), Single Turn (scarf cut), and Spiral (multiturn) PTFE Backup Rings.

Material range:

100%virgin PTFE for light and medium load requirements.

PTFE with filler( Glass/Graphite/Carbon/Bronze)for greater load requirements.

Virgin PTFE 100% PTFE
Inorganic filler PTFE Glass fiber, Graphite, Bronze, Carbon fiber, MoS2
Organic filler PTFE Polyimide, Aromatic Polyester, Polypheylene Sulfide

In a sealing application, backup rings provide added extrusion resistance and prevent damage to o-rings and seals when subjected to high pressures, larger extrusion gaps, and/or high temperatures.

Extrusion failure is one of the most common types of o-ring failure. When the internal pressure of an application becomes too great, the o-ring will actually extrude into the clearance gap. This extrudate will quickly be nibbled away causing a loss of material, and once sufficient material is lost, seal failure will quickly follow.

There are three options to prevent this, the first of which is to reduce the clearances to lower the extrusion gap. This is obviously an expensive option, so a cheaper solution is to raise the durometer of the o-ring. Even though a higher durometer o-ring offers superior extrusion resistance, this is often not a feasible solution due to material availability, and to the fact that harder durometer materials have limited low-pressure sealing ability. The last and best option is the addition of a backup ring. A backup ring is a ring of hard, extrusion resistant material such as high-durometer Nitrile, ® (FKM), or PTFE.

A backup ring is designed to fit between the o-ring and the extrusion gap and prevent the extrusion of the o-ring. Depending upon the direction of pressure in the sealing application, you can either use one backup ring or two backup rings. If unsure, it is always best to use two backup rings per one o-ring.

Commenly all back up rings in in Nitrile 90 Durometer and FKM 90 Durometer.

We can also provide contoured backup rings in other materials by request.
