Value Collection ZMSCU70112 O-ring Dash 112 Polyurethane 10-pack

Product Description

The VALUE COLLECTION ZMSCU70112 is a Dash 112 polyurethane O-ring with a 0.500 inch inside diameter, a 0.688 inch outside diameter, and a 0.094 inch round cross-section thickness. Rated at 70 durometer (hard hardness rating), this O-ring is designed for static and dynamic sealing applications across hydraulic, pneumatic, and fluid-handling systems. It handles a working temperature range of -65 degrees F to 200 degrees F and resists petroleum oils, hydrocarbon fuels, oxygen, ozone, and general weathering. Sold in a package of 10, this part suits plumbers, HVAC technicians, and industrial maintenance professionals working on equipment that contacts fuel or oil-based media.

The ZMSCU70112 is suited for use in residential and commercial applications involving hydraulic cylinders, pneumatic fittings, fuel line connections, and general fluid system maintenance. Its polyurethane construction provides durability in environments with petroleum-based fluids and ozone exposure. This O-ring is not recommended for use with acids, ketones, or chlorinated hydrocarbons. Some polyurethane compounds can also be sensitive to water and humidity exposure, so verify compatibility with wet or steam environments before installation.

Compatibility

Designed as an OEM-style replacement O-ring for applications requiring a Dash 112 dimension with polyurethane material compatibility in petroleum oil and hydrocarbon fuel service environments.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Always depressurize and isolate the system before replacing any O-ring seal. Lubricate the O-ring lightly with a compatible lubricant before installation to prevent tearing during assembly. Avoid overstretching during fitting, and inspect the seating groove for burrs or damage before installing the new ring.
