Part number V4X33.5 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 33.5 mm (1.319 in), a cross section of 4 mm (0.157 in), and an outside diameter of 41.5 mm (1.63 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.
The material holds up against aromatic hydrocarbons, engine and transmission fluids, and many acids. That behavior comes from the compound itself: Viton® (FKM) offers long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with ketones and esters or low-molecular-weight organic acids.
Common environments for this compound include aerospace, semiconductor equipment, and chemical processing.
Reference part number V4X33.5 when ordering; the item is sold individually. Unit weight is approximately 2.7099 g. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
