Product Specification

-
This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 15 mm (0.591 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 20 mm (0.79 in), catalogued under part number H2.5X15. It remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against hydraulic fluids, petroleum-based oils, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

It sees regular use in fluid power, agricultural equipment, and general industrial maintenance.

H2.5X15 ships individually. Unit weight is approximately 0.328 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
