3.5MM CS X 54MM ID BLACK BUNA 70D

The H3.5X54 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 54 mm (2.126 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 61 mm (2.4 in). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. This material stands up to hydraulic fluids, petroleum-based oils, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving strong acids or automotive brake fluid call for a different compound.

Typical settings include general industrial maintenance, hydraulic and pneumatic systems, and construction equipment.
