Value Collection ZMSCU70009 O-ring Polyurethane Dash 009

Product Description

The VALUE COLLECTION ZMSCU70009 is a Dash 009 polyurethane O-ring with a round cross section, designed for static and dynamic sealing applications in fluid and gas handling systems. It measures 0.219 inches inside diameter, 0.344 inches outside diameter, and 0.0625 inches thick. Made from 70-durometer polyurethane, this O-ring delivers strong resistance to petroleum oils, hydrocarbon fuels, oxygen, ozone, and general weathering. Plumbers, HVAC technicians, and fluid-system mechanics use this O-ring as a reliable sealing element in fittings, valves, cylinders, and pumps operating across a broad temperature range.

This O-ring is suited for residential and light commercial applications where petroleum-based fluids or hydrocarbon fuels are present. It is commonly installed in hydraulic fittings, pneumatic connections, fuel system components, and valve assemblies. The Dash 009 size is a standard industry designation, making it a straightforward drop-in choice for equipment requiring that cross-section profile. It is not recommended for use with acids, ketones, or chlorinated hydrocarbons, and some polyurethane compounds may be sensitive to prolonged water or humidity exposure.

Key Features

• 70-durometer hardness rated as hard for firm, reliable sealing under pressure
• Resistant to petroleum oils, hydrocarbon fuels, oxygen, ozone, and weathering
• Round cross section conforms to standard Dash 009 groove dimensions
• Rated for service temperatures from -65 degrees F to 200 degrees F
• Not recommended for acids, ketones, or chlorinated hydrocarbon environments
• Sold in a package of 10 units

Compatibility

Designed as a standard Dash 009 O-ring replacement for fittings, valves, cylinders, and fluid-handling assemblies requiring a 0.219-inch ID, 0.344-inch OD polyurethane seal.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Always depressurize and de-energize the system fully before removing existing O-rings or installing new ones. Lubricate the O-ring with a compatible fluid prior to installation to prevent tearing during assembly. Avoid overstretching the O-ring, and confirm groove dimensions match the Dash 009 specification before installation.
