O-Ring Groove Design For Packing Preformed, Elastomeric O-Ring Seals,
Static, Radial Squeeze, Metric
Description / Abstract:
This recommended practice provides the design criteria for
static elastomeric O-ring seal applications, radial squeeze groove
dimensions for aerospace metric O-ring seal sizes as specified in
MA2010. The conditions considered to formulate the design criteria
are also described, e.g., seal stretch, cross-section reduction,
squeeze, and swell.
The following static, radial squeeze, O-ring groove categories have been incorporated:
a. Rod mounted O-ring groove
b. Bore mounted O-ring groove
The O-ring groove design is based on 2% minimum stretch and the following nominal percentage squeeze which is based on the mean gland depth (t nom) and the mean O-ring cross-section diameter (d2nom). This criteria is similar to ARP1232.
