O Ring Gland Design Guide >> O-Ring for Static Radial, Axial & Reciprocating Applications

O Ring Gland Design Guide

The O ring cross section is squeezed radially in the groove between the inside (ID) and outside (OD).

Static Radial Applications
Common Fixed Seal

The O ring cross section is squeezed axially in the groove similar to a flat gasket
Static Axial Applications
Face Seals

Reciprocating seals refer to seals used in applications that slide back and forth. This motion introduces friction, which creates design considerations different from those of static seals.

The O ring may be housed in a groove (rod seal) in the cylinder wall instead of a groove in the piston surface (piston seal) without any change in design limitations or seal performance.

Dynamic Reciprocating Applications
