Value Collection ZMSCU70010 O-ring Polyurethane 70A Pack 10

Product Description

The VALUE COLLECTION ZMSCU70010 is a polyurethane O-ring with a round cross section, sold in a pack of 10. It measures 0.25 inches inside diameter, 0.375 inches outside diameter, and 0.0625 inches thick, conforming to Dash 010 sizing. Rated at 70 Shore A hardness, this O-ring is suited for static and dynamic sealing applications where resistance to petroleum oils, hydrocarbon fuels, oxygen, ozone, and weathering is required. HVAC technicians, plumbers, and mechanical contractors use polyurethane O-rings in fluid system connections, valve bodies, and fittings across a range of service environments.

This O-ring is used in residential and commercial applications involving petroleum-based fluids and hydrocarbon fuel systems. Typical install scenarios include pump seals, valve stems, and threaded fitting connections where a durable elastomeric seal is needed. Note that this material is not recommended for use with acids, ketones, or chlorinated hydrocarbons. Some urethane compounds are also sensitive to water and humidity, so verify compatibility with the service fluid before installation.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical professional. Depressurize and isolate the system before removing or installing any O-ring seal. Inspect the mating groove for nicks, scoring, or debris before seating the O-ring. Do not stretch the O-ring beyond its natural diameter during installation, and confirm chemical compatibility with the service fluid prior to use.
