Value Collection ZBD9978 O-ring Nbr Dash 110 0.38 in Id

Product Description

The VALUE COLLECTION ZBD9978 is a Dash 110 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 0.38 inches inside diameter, 0.56 inches outside diameter, and 0.094 inches thick. NBR compound delivers reliable resistance to petroleum-based fluids, oils, and fuels, making this O-ring a dependable choice for sealing applications in HVAC, plumbing, and fluid-handling systems. The durometer hardness of 70 Shore A provides firm compression without excessive deformation under load. Rated for service from -40 degrees F to 275 degrees F, this O-ring maintains a consistent seal across a wide range of operating temperatures encountered in residential and commercial trade work.

This O-ring is suited for use in hydraulic fittings, refrigerant service valves, water connections, and pneumatic assemblies where a standard Dash 110 cross-section seal is required. Licensed HVAC technicians, plumbers, and fluid-systems mechanics commonly stock Dash 110 O-rings for field repairs on valves, manifolds, and threaded fittings. The NBR material is compatible with mineral oils, water, and many common refrigerant oils, though it should not be used with ozone-rich environments or strongly oxidizing media.

Key Features

• Dash 110 standard sizing: 0.38 inches ID x 0.56 inches OD x 0.094 inches thick
• Nitrile Butadiene Rubber (NBR) construction resists petroleum fluids, oils, and water
• 70 Shore A hardness rating for firm, consistent sealing under compression
• Operating temperature range: -40 degrees F to 275 degrees F
• Round cross section for uniform groove seating and reliable static or dynamic sealing

Compatibility

Designed as a standard Dash 110 O-ring replacement for hydraulic, pneumatic, plumbing, and HVAC fluid-handling assemblies that specify an NBR seal at this cross-section size.

Installation Notes

O-ring installation should be performed by a qualified technician following system-specific depressurization and lockout procedures before disassembly. Lubricate the O-ring with a compatible grease or fluid prior to seating to prevent pinching or tearing during assembly. Inspect the groove and mating surfaces for nicks or corrosion before installing. Do not stretch the O-ring beyond what is needed to seat it, as overstretching reduces effective cross-section and can cause premature seal failure.
