BRT Bearing Gaskets Back-up rings
BRT back-up rings，Can be made of PTFE or nylon material.
Back-up rings are used to prevent the O-ring from entering the clearance gap.
When high pressures are exerted on the O-ring，the hard back-up ring material will keep the O-ring material from flowing into the gap, which will prevent premature failure.

Description
Structural Design:
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.
PTFE gaskets have great resistance to most mineral and organic chemicals such as acids, bases, and solvents, and can be used up to approximately 240°C.
PTFE gaskets have good ozone resistance and gas impermeability.
BRT helps to prevent extrusion, a common form of O-ring failure in high-pressure environments, and reduces the risk of leakage. Especially in applications with fluctuating pressure, back-up rings are essential. Their shape and positioning provide critical support to the O-ring, contributing to a stable and reliable sealing system.
Summary of Advantages:
- Has excellent chemical resistance
- Can maintain its shape and function even under extreme conditions
- Low friction coefficient
- High pressure creep resistance
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
