-332 BLACK BUNA 70D O-RING

H70332 is an AS568-332 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 2.35 in (59.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.77 in (70.36 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to petroleum-based oils, hydraulic fluids, and water. Buna-N (Nitrile) is known for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ketones or polar solvents.

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

H70332 ships individually. Unit weight is approximately 5.5662 g. 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.
