(a) Rubber compound needed 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.

O-rings and seals from Parker and Chomerics are available in standard sizes and compounds including Viton FKM fluorocarbon O-rings, silicone O-rings, Kalrez O-rings, perfluoroelastomer FFKM O-rings, buna nitrile O-rings, Aflas O-rings, urethane O-rings, fluorosilicone O-rings, metric Viton O-rings, neoprene/chloroprene metric O-rings and encapsulated O-rings. Parker Viton O-rings are available in both standard and metric sizes, often available from inventory. 

Viton O-rings (FKM/fluorocarbon) - Viton O-rings offer strong chemical compatibility with good high temperature performance and good compression set resistance.

Fluorosilicone O-rings - Good resistance to fuel, oil and solvent resistance for ozone, aromatic hydrocarbons, sunlight and chlorinated materials.

Buna O-rings (NBR, nitrile) - excellent oil, fuel and petroleum resistance. Good for greases, hydraulic fluids, water.

Ethylene Propylene O-rings (EPDM) - Good for resistance to steam/hot water, alkalies, alcohol, automotive fluids.

Silicone O-rings - Long life against sunlight and ozone in dry heat applications.

Neoprene O-rings - Cost effective solution for good ozone resistance, and fair resistance to petroleum oils.
