Product Description
The 100-20031 is a PTFE backup ring designed to prevent O-ring extrusion in hydraulic and pneumatic system glands. This anti-extrusion retainer supports elastomeric seals under high pressure, protecting them from nibbling or deformation at gland interfaces. Manufactured to SAE AS5781/AS5782 and MS28773 specifications, the ring provides precise dimensional control for reliable sealing performance.
Installed behind primary O-rings in actuators, valves, and fluid system components, the backup ring maintains seal integrity during pressure cycling and temperature variations. Size selection follows AS4716/AS5857 gland dimension standards to ensure proper fit and function.
