Part number H1X42 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 42 mm (1.654 in), a cross section of 1 mm (0.039 in), and an outside diameter of 44 mm (1.73 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.
It resists petroleum-based oils, propane and butane, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) offers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.
Typical settings include construction equipment, agricultural equipment, and hydraulic and pneumatic systems.
H1X42 ships individually. Unit weight is approximately 0.1345 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
