O-rings are used for sealing liquids or
gases against leakage and loss. Most O-rings are elastomers, although
rings are also available in hollow and solid metals, plastics and
PTFE. When properly designed into an appropriate 'gland', an O-ring
can seal against a wide range of pressures and temperatures, cost-effectively
and with minimal maintenance.
It is critical when designing an O-ring into an application to consider
the gland size/fit, chemical compatibility of the fluid or gas on
the seal, compression forces, temperature variations, pressure requirements,
and any other outstanding issues that might adversely effect the seal.

(a) Rubber compound must be added when ordering by the 2-size number
(i.e., 2-007 N0674-70).
(b) This chart provides dimensions for standard (AN) shrinkage materials
ONLY, corresponding to AS568A dimensions. Compounds with different
shrinkage rates (non-AN) will produce slightly different dimensions
and tolerances.
(c) Call for more information when ordering to a Military, AMS or
NAS material Specification.
