2MM CS X 43.5MM ID BLACK FKM 75D

Ordered as V2X43.5, this is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 43.5 mm (1.713 in), a cross section of 2 mm (0.079 in), and an outside diameter of 47.5 mm (1.87 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Source specification: Metric O-RING, JIS S44.

Expect good resistance to aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for very low compression set at elevated temperature and 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. Applications involving ketones and esters or amines call for a different compound.

Common environments for this compound include aerospace, automotive fuel systems, and chemical processing.

Reference part number V2X43.5 when ordering; the item is sold individually. Unit weight is approximately 0.7968 g. Check the compound against your process media, pressure and temperature before committing to a design.
