Square Ring Seals

Square Rings

A Square-Ring is just like an O-ring which has a circular top view. However, the difference lies in its cross-sectional view, which is square shaped. Square rings offer the sealing function in a more superior manner compared to O-rings and at lower costs compared to other sealing devices. Square rings can comfortably fit in o-ring grooves with the same diameters. In most static applications, a square ring can serve as a direct replacement for an o-ring and in fact can even perform high pressure sealing functions as well as or better than an O-ring

Product Overview

  • No tooling fee for custom size square rings and washers
  • Can be made in almost any material and color
  • Ideal in applications requiring high sealing load force
