Value Collection ZMSCQH70110 O-ring Dash 110 Nbr 70A Pack 100

Product Description

The VALUE COLLECTION ZMSCQH70110 is a Dash 110 O-ring with a Quattro X cross section, manufactured from nitrile butadiene rubber (NBR) at 70 Shore A durometer. It measures 0.375 inches inside diameter, 0.563 inches outside diameter, and 0.0937 inches thick. The X-profile cross section provides four sealing lobes instead of the traditional round, improving seal integrity under dynamic and static load conditions. Rated for service from -30 degrees F to 250 degrees F, this O-ring suits fluid and pneumatic sealing applications across HVAC, plumbing, and hydraulic systems. Each package contains 100 pieces sold as a unit.

This O-ring is well suited for residential and light commercial applications where NBR material is appropriate — including refrigerant line fittings, water and hydraulic fluid connections, and pneumatic port sealing. The Dash 110 size is a common ANSI standard dimension used throughout HVAC, plumbing, and fluid power equipment. Licensed tradespeople and MRO professionals install these during routine seal replacement, valve service, and fitting assembly. The X cross section makes it a functional upgrade over standard round-profile O-rings in the same dash size where groove geometry permits.

Key Features

• Quattro X cross section provides four-lobe sealing geometry for improved static and dynamic seal performance
• Nitrile butadiene rubber (NBR) construction resists petroleum-based fluids, water, and hydraulic oils
• 70 Shore A durometer rated Hard — suitable for moderate-pressure sealing applications
• Operating range of -30 degrees F to 250 degrees F covers most HVAC, plumbing, and fluid power service conditions
• ANSI Dash 110 standard size for drop-in replacement of worn or damaged O-rings in matching grooves
• Package of 100 units supports bench stock, service van inventory, and production line use

Compatibility

Designed as a standard Dash 110 ANSI O-ring replacement for any application requiring a 0.375-inch ID nitrile seal with X cross section profile and a 70 Shore A durometer rating.

Installation Notes

O-ring installation is performed by licensed plumbers, HVAC technicians, and hydraulic technicians depending on the application. Always depressurize and de-energize the system before removing or replacing seals. Clean the groove of debris and inspect for groove damage before seating the new O-ring. Avoid twisting the O-ring during installation; a light application of compatible lubricant helps seat the seal without distortion.
