O-ring Types & Using Instruction

The majority of o-ring seals can be categorized into one of the three following physical arrangements.

Piston O-ring

For Piston O-ring , an o-ring is installed in a groove that is machined into the OD of the “piston.” The piston and the installed o-ring are then inserted into the bore. The o-ring seals radially.

Rod O-ring

With Rod O-ring, an o-ring is first installed into a groove that is machined into the ID of the bore. The rod is then inserted into the bore through the o-ring. The o-ring seals radially.

Face O-ring

For Face O-ring, an o-ring is installed in a groove that is machined into a flat face around a hole. A second flat face then seals against the o-ring.The o-ring seals axially.

Triangular O-ring

Other arrangements, such as triangular o-rings (see diagram upside) or variations on the above three arrangements with dovetail or half-dovetail grooves, are encountered but are much less common.
