568-352 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90352, an AS568-352 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 4.85 in (123.19 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.27 in (133.86 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to petroleum oils, impact and shock loading, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers outstanding extrusion resistance at elevated pressure and 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 hot water and steam or acids and bases call for a different compound.

It sees regular use in off-highway equipment, high-pressure fluid power, and construction machinery.

Stocked as U90352 and sold individually. Nominal inside diameter is listed as 4 7/8 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.
