This o-ring is supplied in black Viton® (FKM) 75 Shore A with an inside diameter of 38 mm (1.496 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 43 mm (1.69 in), catalogued under part number V2.5X38. It remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Viton® (FKM) is specified for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. Expect good resistance to many acids, chlorinated solvents, and aggressive chemicals. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or hot water and steam are present.
It sees regular use in aerospace, automotive fuel systems, and semiconductor equipment.
V2.5X38 ships individually. Unit weight is approximately 1.1359 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
