-122 BLACK FKM 75D O-RING

Ordered as V75122, this is an AS568-122 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 1.112 in (28.24 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.318 in (33.48 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Viton® (FKM) is valued for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. It resists aromatic hydrocarbons, engine and transmission fluids, and many acids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or low-molecular-weight organic acids will shorten service life.

Maintenance and OEM teams specify it across aerospace, semiconductor equipment, and oil and gas.

Order part number V75122, sold individually. Unit weight is approximately 0.97 g and nominal inside diameter is listed as 1 1/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
