Value Collection ZMSCQH70113 O-ring Dash 113 Nbr X Section

Product Description

The VALUE COLLECTION ZMSCQH70113 is a Dash 113 O-ring with an X-profile (quattro) cross section, manufactured from nitrile butadiene rubber (NBR). NBR provides reliable resistance to petroleum-based fluids, hydraulic oils, and common refrigerants, making this O-ring a go-to sealing solution across HVAC, plumbing, and fluid-handling applications. It measures 9/16 inches (0.5630 inches) inside diameter, 3/4 inches (0.7500 inches) outside diameter, and 3/32 inches (0.0937 inches) thick. The X-profile cross section offers four sealing lips instead of the single sealing surface of a standard round O-ring, improving stability in dynamic and static groove applications. Licensed trades and maintenance techs use this part for sealing fittings, valves, and fluid circuits during service or assembly work.

This O-ring is suited for static and low-speed dynamic sealing applications in residential and light commercial systems. Typical installations include refrigeration service valves, hydraulic fittings, plumbing shutoff valves, and fluid-system connections where an NBR compound is chemically compatible with the working fluid. The Dash 113 sizing is a standard AS568 dimension, so it fits standard Dash 113 O-ring grooves across a wide range of OEM and aftermarket hardware. Parts are packaged in a quantity of 100 per order unit, making this a practical stock item for service shops and MRO supply.

Compatibility

Designed as a standard AS568 Dash 113 replacement O-ring for any valve, fitting, or fluid-system component specifying a Dash 113 groove with an NBR-compatible sealing material.

Installation Notes

O-ring replacement is typically performed by licensed HVAC technicians, plumbers, or hydraulic system mechanics. Always depressurize and isolate the fluid circuit before removing the old O-ring, and inspect the groove for nicks or debris that could damage the new seal. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent tearing during assembly. Verify chemical compatibility between the NBR compound and the working fluid before installation.
