Product Specification

-
Part number H5X205 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 205 mm (8.071 in), a cross section of 5 mm (0.197 in), and an outside diameter of 215 mm (8.46 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to propane and butane, hydraulic fluids, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for 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. Verify compatibility before use with automotive brake fluid or ketones.

You will find this material specified across agricultural equipment, fluid power, and automotive.

Reference part number H5X205 when ordering; the item is sold individually. Unit weight is approximately 15.743 g. Application requirements vary, so validate compatibility with your process conditions prior to 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.
