Ordered as V2X128, this is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 128 mm (5.039 in), a cross section of 2 mm (0.079 in), and an outside diameter of 132 mm (5.2 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The material holds up against petroleum oils and fuels, engine and transmission fluids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) offers outstanding high-temperature capability, excellent resistance to compression set and permeation. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in hot water and steam or low-molecular-weight organic acids.
You will find this material specified across automotive fuel systems, high-temperature process equipment, and oil and gas.
Reference part number V2X128 when ordering; the item is sold individually. Unit weight is approximately 2.36 g.
