Product Specification

-
H1.6X4.7 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 4.7 mm (0.185 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 7.9 mm (0.31 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists hydraulic fluids, water, and petroleum-based oils. Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or automotive brake fluid.

Common environments for this compound include general industrial maintenance, construction equipment, and fluid power.

This item is sold individually under part number H1.6X4.7. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
