Value Collection ZMSCQH70115 O-ring Dash 115 Nbr 100 Pack

Product Description

The VALUE COLLECTION ZMSCQH70115 is a Dash 115 O-ring with an X-profile (quattro) cross section, manufactured from nitrile butadiene rubber (NBR). It measures 0.688 inches inside diameter, 0.875 inches outside diameter, and 0.0937 inches thick. The X-profile cross section provides four sealing lips rather than a single round contact surface, which reduces friction and minimizes spiral twist during dynamic applications. NBR compound offers solid resistance to petroleum-based oils, hydraulic fluids, and fuels, making this O-ring a standard choice for sealing applications across HVAC, plumbing, and fluid-handling assemblies. Licensed plumbers, HVAC technicians, and millwrights regularly stock this size for preventive maintenance and field repair work. Sold in a 100-piece package.

This O-ring is suited for static and low-speed dynamic sealing applications in residential and light commercial equipment. Common use cases include refrigerant line fittings, hydraulic manifold ports, pump housings, and valve assemblies where a Dash 115 groove has been machined or specified by the OEM. The X-profile geometry is particularly useful in grooves where a standard round-section O-ring would roll or displace under reciprocating motion. Techs handling refrigeration or plumbing service will find this size on standard connection hardware across a wide range of system types.

Key Features

• X-profile (quattro) cross section provides four sealing lips for reduced friction and improved twist resistance
• Nitrile butadiene rubber (NBR) compound compatible with petroleum-based oils, hydraulic fluids, and fuels
• Dash 115 standard sizing for drop-in fitment in correctly dimensioned O-ring grooves
• 0.688 inches ID and 0.875 inches OD for precise groove engagement
• 100-piece package supports stocking for repeat-service and fleet maintenance use
• UNSPSC Code 31401500 for procurement and catalog cross-reference

Compatibility

Designed as a standard replacement for any Dash 115 O-ring groove application specifying an X-profile cross section in nitrile butadiene rubber.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or hydraulic system technicians depending on the host equipment. Always depressurize and de-energize the system before removing any fitting or valve containing an O-ring. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating it in the groove to prevent tearing during assembly. Do not use petroleum-based lubricants with O-ring compounds that are not petroleum-compatible, and verify that NBR is the correct elastomer for the fluid being sealed.
