The V75MD310 is an AS568-310 blue Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 0.475 in (12.07 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 0.895 in (22.73 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.
This material stands up to many acids, engine and transmission fluids, and aggressive chemicals. Viton® (FKM) is known for very low compression set at elevated temperature, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in hot water and steam or low-molecular-weight organic acids.
The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. It sees regular use in oil and gas, automotive fuel systems, and aerospace.
