Value Collection ZMSCQH70012 O-ring Dash 012 Nbr 70A Pack 100

Product Description

The VALUE COLLECTION ZMSCQH70012 is a Dash 012 nitrile butadiene rubber (NBR) O-ring with an X-profile cross section, sized at 0.375 inches inside diameter, 0.500 inches outside diameter, and 0.0625 inches thick. The X-shaped cross section provides four-point sealing contact, improving resistance to spiral twist and blowout compared to a standard round cross section. With a 70 Shore A durometer rating, this O-ring offers firm resistance to compression set and extrusion under moderate pressure. It is suited for static and dynamic sealing applications in fluid and pneumatic systems and is installed by plumbers, HVAC technicians, and mechanical service technicians. Sold in packs of 100.

NBR O-rings in this size range are commonly used in residential and light commercial plumbing fittings, HVAC refrigerant-side connections, hydraulic couplings, pneumatic valves, and general-purpose fluid sealing assemblies. The Dash 012 designation is a standard sizing reference recognized across trade and industrial applications. The temperature range of -30 degrees F to 250 degrees F makes this O-ring appropriate for most heated-water, chilled-water, and compressed-air service environments encountered in trade work.

Key Features

• X-profile cross section provides four-point contact sealing, reducing spiral twist failure in dynamic applications
• 70 Shore A durometer rating delivers firm compression resistance suitable for moderate-pressure service
• Nitrile butadiene rubber (NBR) compound offers good resistance to oils, fuels, and water-based fluids
• Operating temperature range of -30 degrees F to 250 degrees F covers most HVAC, plumbing, and pneumatic service conditions
• Dash 012 standard sizing for straightforward cross-referencing and replacement
• Pack quantity of 100 supports stocking for recurring maintenance and repair work

Compatibility

Designed as a standard Dash 012 O-ring replacement for static and dynamic sealing applications in plumbing, HVAC, pneumatic, and hydraulic assemblies where a 0.375-inch ID, 0.500-inch OD NBR seal is specified.

Installation Notes

Shut off fluid or air supply and relieve system pressure before removing any fitting or valve containing an O-ring. Inspect the groove and mating surfaces for burrs or corrosion before installing a new seal. Lightly lubricate the O-ring with a compatible grease or fluid before seating to prevent tearing during assembly. Verify the replacement Dash number matches the original seal specification before installation.
