SPIRA MANUFACTURING

Custom O-Ring Gaskets

Custom O-ring gaskets are made using a standard or custom size groove mounted Spira gasket. This includes: Spira-Shield, Enduro-Shield, Flexi-Shield and “D” Multi-Seal gaskets (in addition to any other groove mounted gasket). O-rings can be used either in circular or rectangular groove applications.

We assemble the o-rings either by winding one end of the spiral into the other and soldering (Spira-Shield and Quick-Shield) or using adhesive (Enduro-Shield, Flexi-Shield and “D” Multi-Seal).

When installing a “D” Multi-Seal o-ring into a rectangular groove, put the corners in first, then press the gasket into the straight sections of the groove. We recommend a corner radius of 1 1/2 times the diameter of the spiral or width of the “D” Multi-Seal gasket.
