It compresses into its gland to block fluid or gas migration across a joint.
As a material, Polyurethane (AU/EU) is widely chosen for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. This material stands up to ozone, extrusion under high pressure, and abrasion and wear. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). It should not be specified for service in hot water and steam or ketones.
It sees regular use in mining and heavy equipment, high-pressure fluid power, and press and forming equipment.
Reference part number U90152 when ordering; the item is sold individually. Nominal inside diameter is listed as 3 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
