APG stocks the U70169, an AS568-169 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 7.487 in (190.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.693 in (195.4 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Polyurethane (AU/EU) is known for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. The compound resists impact and shock loading, petroleum oils, and ozone. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or acids and bases will shorten service life.
You will find this material specified across high-pressure fluid power, off-highway equipment, and hydraulic cylinders.
Reference part number U70169 when ordering; the item is sold individually. Nominal inside diameter is listed as 7 1/2 inch. 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.
