3MM CS X 49MM ID BLACK FKM 75D

Part number V3X49 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 49 mm (1.929 in), a cross section of 3 mm (0.118 in), and an outside diameter of 55 mm (2.17 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to many acids, chlorinated solvents, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers 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 amines or ketones and esters call for a different compound.

You will find this material specified across chemical processing, aerospace, and high-temperature process equipment.

Reference part number V3X49 when ordering; the item is sold individually. Unit weight is approximately 2.1192 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
