*4282-514AD MINNESOTA RUBBER QUAD RING

Ordered as VQ4282, this is an AS568-282 black Viton® (FKM) 75 Shore A quad profile Quad-Ring built to an inside diameter of 15.955 in (405.26 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 16.233 in (412.32 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

This material stands up to aggressive chemicals, petroleum oils and fuels, and many acids. That behavior comes from the compound itself: Viton® (FKM) offers outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

Common environments for this compound include oil and gas, semiconductor equipment, and chemical processing.

Stocked as VQ4282 and sold individually. Nominal inside diameter is listed as 16 inch. 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.
