The H1X37 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 37 mm (1.457 in), a cross section of 1 mm (0.039 in), and an outside diameter of 39 mm (1.54 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Buna-N (Nitrile) is specified here for low compression set under sustained load, reliable performance in both static and dynamic service. Expect good resistance to hydraulic fluids, many alcohols, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with polar solvents or ketones.
Common environments for this compound include agricultural equipment, hydraulic and pneumatic systems, and construction equipment.
H1X37 ships individually. Unit weight is approximately 0.117 g. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
