-342 BLACK FKM 75D O-RING

The V70342 is an AS568-342 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 3.6 in (91.44 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.02 in (102.11 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is specified for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. It resists aromatic hydrocarbons, petroleum oils and fuels, and aggressive chemicals. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or ketones and esters are present.

Maintenance and OEM teams specify it across oil and gas, high-temperature process equipment, and aerospace.

Reference part number V70342 when ordering; the item is sold individually. Unit weight is approximately 12.41 g and nominal inside diameter is listed as 3 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
