Product Specification

-
H1.5X56 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 56 mm (2.205 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 59 mm (2.32 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. It resists water, propane and butane, and many alcohols. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where ozone and direct sunlight or ketones are present.

Maintenance and OEM teams specify it across agricultural equipment, general industrial maintenance, and automotive.
