Value Collection ZBDMP9978 O-ring 0.38 in Id Nbr Dash 110

Product Description

The VALUE COLLECTION ZBDMP9978 is a Dash 110 O-ring made from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 0.38 inches inside diameter, 0.56 inches outside diameter, and 0.0937 inches thick. NBR compound provides resistance to petroleum-based fluids, oils, and fuels, making this O-ring a standard choice for sealing applications in HVAC, plumbing, and fluid-handling systems. The material carries a hardness rating of 70 Shore A, classified as hard, and is rated for continuous service from -40 degrees F to 275 degrees F. Licensed trades and maintenance technicians use this O-ring as a static or dynamic seal in a wide range of service and repair work.

This O-ring is suited for residential and light commercial applications wherever a Dash 110 NBR seal is specified. Typical uses include valve bodies, fittings, refrigerant-side components, hydraulic couplings, and water service connections. The NBR compound performs reliably in contact with mineral oils, hydraulic fluids, fuels, and water, but is not recommended for use with chlorinated solvents, ketones, or ozone-exposure environments. Plumbers, HVAC technicians, and fluid-system mechanics reach for this size when servicing standard 3/8-inch-bore fittings and port faces.

Key Features

• Wide service temperature range: -40 degrees F to 275 degrees F
• Round cross section for consistent compression and sealing contact
• Minimum order quantity of 10 units for service-stock replenishment

Compatibility

Designed as a standard Dash 110 replacement O-ring for any application specifying a 0.38-inch ID NBR O-ring with a round cross section in hydraulic, plumbing, HVAC, or fluid-handling assemblies.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize and isolate the system before removing the old O-ring. Clean the gland and mating surfaces thoroughly, and apply a compatible lubricant to the O-ring before seating to prevent tearing during assembly. Do not stretch the O-ring beyond its natural elasticity when installing over threads or into a groove.
