Square Rubber Ring

Category

A Square Ring is a sealing device made in the form of a torus (round top view), with a square-shaped cross-section (side view).

Other names for Square Rings are Washer Rings, Lathe-Cut Rings.

The primary reason for using a Square Ring in a sealing application is that they provide more sealing surface area – and at a cost that is comparable to other sealing device. For existing applications, there is no need to change the design or procedures. Square Rings fit in o-ring grooves and are interchangeable size-for-size.

Square Rings are available in a variety of rubber and plastic materials such as NBR, Viton, EPDM, Teflon, etc. In most static applications, a Square Ring will serve as a direct replacement for an o-ring and generally will perform a high-pressure sealing function as well as or better than an o-ring.

Features of Square Rings:

Interchangeable with o-rings size for size
Uses the same groove as an o-ring
Can be used for radial seals
Material is homogenous with no joints or laminations
Edges accurately formed
Extreme close tolerances held on cross-section, ID, and OD
Controlled surface smoothness, hardness, elasticity, toxicity, texture
The modern, economical option for static applications
