APG stocks the U90236, an AS568-236 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 3.234 in (82.14 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.512 in (89.2 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Polyurethane (AU/EU) offers long wear life in dynamic reciprocating service, very high tensile strength and load capacity. The compound resists petroleum oils, impact and shock loading, and extrusion under high pressure. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Exposure to hot water and steam or acids and bases will shorten service life.
Common environments for this compound include construction machinery, hydraulic cylinders, and high-pressure fluid power.
Order part number U90236, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
