Q-119 BUNA 70 Q RING

This quad-ring is supplied in AS568-119 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 0.924 in (23.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.13 in (28.7 mm), catalogued under part number QH70119. It resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Buna-N (Nitrile) delivers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material holds up against water, propane and butane, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). The profile itself contributes lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

Maintenance and OEM teams specify it across construction equipment, agricultural equipment, and general industrial maintenance.

Reference part number QH70119 when ordering; the item is sold individually. Unit weight is approximately 0.536 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
