An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Polyurethane (AU/EU) is specified for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. This material stands up to petroleum oils, abrasion and wear, and impact and shock loading. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It should not be specified for service in hot water and steam or ketones.

Maintenance and OEM teams specify it across hydraulic cylinders, mining and heavy equipment, and construction machinery.

U90366 ships individually. Nominal inside diameter is listed as 7 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
