Product Specification

-
APG stocks the H2X16.5, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 16.5 mm (0.65 in), a cross section of 2 mm (0.079 in), and an outside diameter of 20.5 mm (0.81 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against propane and butane, water, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and low compression set under sustained load. 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.

You will find this material specified across general industrial maintenance, automotive, and fluid power.

This item is sold individually under part number H2X16.5. Unit weight is approximately 0.2307 g. Check the compound against your process media, pressure and temperature before committing to a design.
