Part number H1.5X53 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 53 mm (2.087 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 56 mm (2.2 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
This material stands up to propane and butane, petroleum-based oils, and greases and lubricants. Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or ozone and direct sunlight will shorten service life.
Maintenance and OEM teams specify it across general industrial maintenance, construction equipment, and fluid power.
Order part number H1.5X53, sold individually. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
