Zatkoff 2-373 V1475-75 FKM O-Ring, 75 Durometer, Black, 8.975" ID x 0.210" Cross Section (Pack of 2)

This is a black FKM (fluorocarbon, Viton type) O-ring in standard AS568 size 2-373, made in the V1475-75 compound and packaged by Zatkoff Seals and Packings, a Michigan seal distributor that lists this part in its Parker O-ring line. The 2-373 dash number defines a nominal 9 inch ID by 3/16 inch width ring, with an actual size of 8.975 inch ID and 0.210 inch cross section.

V1475-75 is Parker's general purpose 75 Shore A fluorocarbon compound. It is rated from -15 F to 400 F and resists petroleum oils, mineral and vegetable oils, and aromatic and chlorinated hydrocarbons, which makes it a common choice for hydraulic, fuel, lubrication and chemical process equipment running hotter than nitrile can handle.

Large diameter 2-3xx series O-rings seal flanges, tank and filter housing covers, large cylinder bores and pump and valve bodies. Because the AS568 size is a published standard, this ring interchanges with any 2-373 O-ring of equivalent compound.

Available from King Surplus inventory in Del Rio, Texas.
