Part number H50134 is an AS568-134 black Buna-N (Nitrile) 50 Shore A O-Ring with an inside diameter of 1.862 in (47.29 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.068 in (52.53 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Expect good resistance to many alcohols, water, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ketones or automotive brake fluid will shorten service life.
Maintenance and OEM teams specify it across agricultural equipment, construction equipment, and hydraulic and pneumatic systems.
Order part number H50134, sold individually. Nominal inside diameter is listed as 1 7/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
