Part number V75MD325 is an AS568-325 blue Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 1.475 in (37.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.895 in (48.13 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. The compound resists aromatic hydrocarbons, many acids, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving amines or hot water and steam call for a different compound.
The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across oil and gas, high-temperature process equipment, and chemical processing.
This item is sold individually under part number V75MD325. Nominal inside diameter is listed as 1 1/2 inch. Review your operating media and conditions against this specification before installation.
