Part number HS70250 is an AS568-250 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 4.984 in (126.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.262 in (133.65 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

HNBR (Hydrogenated Nitrile) is specified here for excellent abrasion and tear strength, strong resistance to rapid gas decompression. The material holds up against heat and oxidation, petroleum oils and fuels, and modern refrigerants. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C).

Maintenance and OEM teams specify it across commercial refrigeration, oilfield and downhole equipment, and heavy-duty powertrain.
