4MM CS X 71MM ID BLACK FKM 75D

Part number V4X71 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 71 mm (2.795 in), a cross section of 4 mm (0.157 in), and an outside diameter of 79 mm (3.11 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against aromatic hydrocarbons, many acids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is specified for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

You will find this material specified across aerospace, semiconductor equipment, and automotive fuel systems.

V4X71 ships individually. Unit weight is approximately 5.4834 g. Review your operating media and conditions against this specification before installation.
