Product Specification

-
APG stocks the H2.4X11.3, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 11.3 mm (0.445 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 16.1 mm (0.63 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to hydraulic fluids, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in automotive brake fluid or ozone and direct sunlight.

Common environments for this compound include construction equipment, agricultural equipment, and general industrial maintenance.

This item is sold individually under part number H2.4X11.3. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
