WitrynaMost o-rings are designed to operate at pressures up to 1,500 psi. At higher pressures, the material must have enough strength to resist extruding into the clearance gap. … WitrynaO-Ring Extrusion GAP CHART Read more Back-up Rings for o-rings Back-up Rings Back-up Rings are installed on the downstream side of an O-Ring to help prevent …
WitrynaBack-Up Rings Extrusion failure is one of the most common types of O-ring failure. When the pressure becomes too great, the O-ring will actually extrude into the clearance gap. This will quickly nibble the O-ring away causing a loss of material, and once sufficient material is lost, seal failure will quickly follow. WitrynaTechniques to avoid extrusion in high-pressure applications include decreasing the clearance gap, increasing the durometer, and adding a backup ring(s). Clearance …
Witryna24 lip 2015 · When enough force is applied, the o-ring will move toward the low-pressure side until it contacts the side of the groove. Additional pressure or force will deform the o-ring toward the extrusion gap. … WitrynaThe diametrical compression presents a rubbing force amongst the O Ring and the groove that keeps it in the fixed setting. O Rings are designed to deform, the elastomer element runs up to the extrusion gap, entirely sealing it from leakage, until the stress implemented is adequate enough to conquer the rubbing constraints and deform the …
WitrynaIts possible the O-ring material can be selected for greater extrusion resistance, however if the pressure is high enough, or the gap large enough, any O-ring or other seal profile will extrude. Possibly a thermoplastic or rigid seal will be needed in this event.
WitrynaExtrusion gaps and back-up rings. The size of the permissible extrusion gap (→ Gap extrusion) depends mainly on the seal material, temperature and operating pressure. Harder materials (→ Materials) provide a certain resistance to gap extrusion. When the permissible extrusion gap for the pressure and temperature in application is … direct mail mortgage brokersWitrynaMaximum extrusion gap = F max (see drawing below).

The second role is to make the sealing surface perpendicular to the oring - no more cavity.

What’s Seen: Nibbled or ruffled edges can be observed on the side of the o-ring receiving lower pressures. What Causes It: The o-ring is pushed into a clearance gap in the event of high pressures. Pressure surges can bring about the opening and closing of the clearance gap. for you to reference or for your reference
