Value Collection ZMSCQH70016 O-ring Dash 016 Nbr 100-pack

Product Description

The VALUE COLLECTION ZMSCQH70016 is a Dash 016 O-ring featuring an X-profile (quattro) cross section, manufactured from Nitrile Butadiene Rubber (NBR). It measures 5/8 inch (0.6250 inches) inside diameter, 3/4 inch (0.7500 inches) outside diameter, and 1/16 inch (0.0625 inches) thick. The X-profile cross section provides four sealing lobes rather than a single round contact point, which reduces the tendency to spiral or roll in dynamic groove applications. NBR compound offers reliable resistance to petroleum-based oils, fuels, and hydraulic fluids, making this O-ring well suited to HVAC, refrigeration, plumbing, and fluid-system maintenance work. This SKU is sold as a pack of 100 units.

This O-ring is commonly used in low-pressure hydraulic fittings, refrigerant service ports, plumbing connections, and mechanical assemblies where a compact static or light-duty dynamic seal is required. The Dash 016 sizing is a standard AS568 dimension, so it fits a wide range of OEM and aftermarket grooves specified to that dash number. Trades that typically stock this size include HVAC technicians working refrigerant circuit fittings, plumbers servicing valved assemblies, and maintenance mechanics maintaining fluid-handling equipment.

Compatibility

Designed for use in any static or light-duty dynamic sealing groove dimensioned to AS568 Dash 016 specifications across HVAC, plumbing, hydraulic, and general mechanical assemblies.

Installation Notes

Power down or depressurize the system fully before disturbing any sealed joint. Inspect the groove for burrs, scoring, or contamination and clean the seating surface before installing the new O-ring. Apply a light coat of compatible lubricant to the O-ring to ease installation and reduce the chance of nicking the sealing surface. Do not overstretch the O-ring during installation; if resistance is excessive, verify the groove dimensions match the Dash 016 specification.
