Value Collection BDNA--9987-1 O-ring Dash 119 Nbr

Product Description

The VALUE COLLECTION BDNA--9987-1 is a Dash 119 O-ring with a 15/16-inch inside diameter and a 3/32-inch cross-section thickness. Molded from Nitrile Butadiene Rubber (NBR) with a 70 durometer hardness rating, it delivers reliable sealing performance in fluid and pneumatic systems. The round cross-section profile seats evenly in standard O-ring grooves, helping prevent leaks at joints and fittings. Licensed plumbers, HVAC technicians, and fluid-system mechanics commonly specify this seal size for maintenance and repair work on pumps, valves, compressors, and related equipment.

This O-ring suits residential and commercial applications where Dash 119 sizing is specified. It is well suited for use in hydraulic lines, refrigeration fittings, water and air systems, and other assemblies calling for a standard inch-series NBR seal. NBR material provides good resistance to petroleum-based oils, fuels, and many common refrigerants, making it a practical choice across HVAC, plumbing, and industrial fluid-handling contexts. Verify fluid compatibility with the specific media in service before installation.

Key Features

• Dash 119 standard sizing: 15/16-inch inside diameter with 3/32-inch thickness
• Nitrile Butadiene Rubber (NBR) construction for resistance to petroleum-based oils and common refrigerants
• 70 durometer hardness balances flexibility with compression resistance for consistent sealing
• Round cross-section profile for reliable, uniform groove seating
• Inch-measurement system for compatibility with standard imperial-dimensioned hardware

Compatibility

Designed as a standard Dash 119 inch-series NBR O-ring for use in valves, pumps, compressors, fittings, and other assemblies requiring this cross-section and inside diameter.

Installation Notes

Licensed plumbers, HVAC technicians, and fluid-system mechanics should de-energize the system and relieve all pressure before removing or replacing O-rings. Clean the groove thoroughly and inspect for scoring or corrosion before seating the new ring. Lightly lubricating the O-ring with a compatible lubricant aids installation and reduces the risk of tearing during assembly. Do not stretch or twist the ring during placement.
