*Q-360 BUNA 70 Q RING

Ordered as QH70360, this is an AS568-360 black Buna-N (Nitrile) 70 Shore A Quad-Ring measuring an inside diameter of 5.85 in (148.59 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.27 in (159.26 mm). The quad-ring provides a dual sealing band on each contact face for improved reliability.

As a material, Buna-N (Nitrile) is specified for strong abrasion and tear resistance, low compression set under sustained load. The compound resists many alcohols, water, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or strong acids. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

Maintenance and OEM teams specify it across fluid power, automotive, and agricultural equipment.
