Product Specification

-

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

Polyurethane (AU/EU) is known for long wear life in dynamic reciprocating service and exceptional abrasion resistance. It resists ozone, abrasion and wear, and impact and shock loading. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with ketones or hot water and steam.

Maintenance and OEM teams specify it across off-highway equipment, construction machinery, and mining and heavy equipment.

U70253 ships individually. Nominal inside diameter is listed as 5 3/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
