General terms used herein are defined as follows:
Squeeze: The dimension by which a packing is distorted from its
molded shape when installed in a packing gland.
Seal: A device to retain fluid within a hydraulic component. The
seal may consist of two or more components such as a packing in a
gland, and a packing and backup ring in a gland, etc.
Packing: The component of a seal which serves as a sealing medium by
nature of its plastic or elastic properties, or its ability to
deform into the shape of the gland.
Gland: The component of the seal which forms the cavity or inclusion
which surrounds and supports the packing and controls the squeeze.
Dynamic seal: A type of seal where there is relative motion
between some part of the gland and the packing, such as a piston or
Static seal: A type of seal where there is no relative motion
between the packing and any part of the gland, although limited
freedom may be provided to permit the packing to change its shape
within the gland when under pressure.
Backup ring: A device used to prevent pressure and friction from
extruding the O-ring packing through the clearance gap of a seal.
TFE : A tetrafluoroethylene resin.
