Product Specification

-
Part number H1.5X20.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 20.5 mm (0.807 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 23.5 mm (0.93 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to greases and lubricants, many alcohols, and petroleum-based oils. Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in polar solvents or ketones.

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

This item is sold individually under part number H1.5X20.5. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
