Back-Up Ring is the pressure seal

Product Advantages:

Easy to install: Designed to precise requirements and manufactured to tight tolerances, they will not come off after fitting

Cost reduction: Within a certain limit of clearance, the O-ring will make an effective seal. The use of retaining rings expands the clearance limit and allows loose assembly of moving parts.

There is a shape to obtain better performance: the design of the profile (regardless of the form of installation) ensures improved performance.

Low price: compared to other types of retaining rings, our retaining rings are less expensive
Extends the working life of O-Rings
Improved lubrication
High pressure resistance

Product Introduction

TECHNICAL DRAWING

The retaining ring is a supplement to the pressure seal (O-ring), which is not a seal itself. The main reason for using the retaining ring is to reduce the gap on the low pressure side of the O-ring and similar seals. The structure of the O-ring and retaining ring is under much greater pressure than the use of the O-ring alone. The retaining ring is moulded into an uninterrupted ring with high hardness rubber material, which is easy to assemble by stretching. Because the retaining ring is neither cut nor spiral, it will not cause local damage to the O-ring. Other types of retaining rings do not have this feature.

The experimental results show that the retainer ring has longer service life and higher reliability than the retainer ring of the modified type, and the working pressure range of the O-ring is expanded.
