DESCRIPTION
Our Square O-rings provide an economical option to traditional o-rings. For existing applications, there is no need to change the design or procedures. Square O-rings fit in O-ring grooves and are interchangeable with O-rings of the same size designation.
Our Square O-rings fit standard AS568 groove dimensions and have the same ID as AS568 o-rings. However, the cross-section dimension is slightly smaller for square o-rings.
Square O-rings can be used for radial seals, and are manufactured to extreme close cross-section, ID and OD tolerances.
Our standard Square O-rings are manufactured out of 70-durometer Nitrile, but can be ordered from many different materials and durometers.
