-335 BLUE FKM 75D O-RING

Ordered as V75MD335, this is an AS568-335 blue Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 2.725 in (69.22 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.145 in (79.88 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to aggressive chemicals, chlorinated solvents, and many acids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where amines or ketones and esters are present.

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 automotive fuel systems, high-temperature process equipment, and oil and gas.

Reference part number V75MD335 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
