Product Specification

-
APG stocks the H50473, an AS568-473 black Buna-N (Nitrile) 50 Shore A O-Ring with an inside diameter of 23.94 in (608.08 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 24.49 in (622.05 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The compound resists hydraulic fluids, water, and petroleum-based oils. Buna-N (Nitrile) delivers strong abrasion and tear resistance, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ketones or ozone and direct sunlight will shorten service life.

Typical settings include hydraulic and pneumatic systems, construction equipment, and general industrial maintenance.

Reference part number H50473 when ordering; the item is sold individually. Nominal inside diameter is listed as 24 inch. 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.
