o-rings

Parker
Sealing Devices is Proud to Offer Parker Seal O-rings.
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.


O-Ring Sizes


(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.
