Product Specification

-
The H1.5X43 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 43 mm (1.693 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 46 mm (1.81 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists many alcohols, water, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in polar solvents or strong acids.

You will find this material specified across general industrial maintenance, automotive, and fluid power.

Stocked as H1.5X43 and sold individually. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
