APG stocks the U70223, an AS568-223 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 1.609 in (40.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.887 in (47.93 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
This material stands up to extrusion under high pressure, petroleum oils, and abrasion and wear. Polyurethane (AU/EU) delivers very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Applications involving acids and bases or ketones call for a different compound.
Typical settings include high-pressure fluid power, hydraulic cylinders, and off-highway equipment.
U70223 ships individually. Nominal inside diameter is listed as 1 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
