3MM CS X 88MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A with an inside diameter of 88 mm (3.465 in), a cross section of 3 mm (0.118 in), and an outside diameter of 94 mm (3.7 in), catalogued under part number V3X88. It creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists petroleum oils and fuels, aromatic hydrocarbons, and many acids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

You will find this material specified across oil and gas, semiconductor equipment, and chemical processing.

V3X88 ships individually. Unit weight is approximately 3.7457 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
