(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 Seal 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-N/Nitrile O-rings, Aflas O-rings, Urethane O-rings, Fluorosilicone O-rings, Metric Viton O-rings, Neoprene / Chloroprene Metric O-rings, 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-N O-rings (NBR, Nitrile) - excellent oils, fuels 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.
