-135 BLUE FKM 75D O-RING

V75MD135 is an AS568-135 blue Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 1.925 in (48.9 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.131 in (54.13 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to aromatic hydrocarbons, engine and transmission fluids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or amines call for a different compound.

This item meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across chemical processing, automotive fuel systems, and semiconductor equipment.

Stocked as V75MD135 and sold individually. Nominal inside diameter is listed as 1 15/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
