2.5MM CS X 43MM ID BLACK FKM 75D

The V2.5X43 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 43 mm (1.693 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 48 mm (1.89 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to petroleum oils and fuels, aromatic hydrocarbons, and many acids. That behavior comes from the compound itself: Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

It sees regular use in chemical processing, aerospace, and high-temperature process equipment.

V2.5X43 ships individually. Unit weight is approximately 1.3071 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
