WHAT IS A SQUARE RING?
|
|
A Square-Ring is a sealing device made in the form of a torus, with a square shaped cross-section.
It is available in a variety of elastomeric and thermoplastic materials. In most static
applications, it is a direct replacement for an O-ring and generally will perform a high pressure
gasketing function as well as or better than an O-ring.
|
 |
The major square-ring features are:
(left: cross section of square ring)
|
| - Interchangeable with O-rings size for size (Standard AS568A sizes) |
| - Uses same groove as O-ring |
| - Can be used for radial seals |
| - Material is homogenous, no joints, no laminations |
| - Edges accurately formed |
| - Extreme close tolerances held on cross-section, I.D. and O.D. |
| - Controlled surface smoothness, hardness, elasticity, toxicity, texture |
| - The modern, economical option for static applications |
| - Available in many compounds |
WHY USE A SQUARE-RING?
|
The primary reason for using a Square-ring in a sealing application is that they perform the sealing function in a
superior manner - and at cost lower than any other comparable 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.
