Value Collection BDNA-9994 O-ring Dash 325 Nbr 1-1/2 in Id

Product Description

The VALUE COLLECTION BDNA-9994 is a Dash 325 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a 1.5-inch inside diameter and a 3/16-inch cross-section thickness. It features a round cross-section profile and is dimensioned to the inch measurement system. NBR compound provides solid resistance to petroleum-based fluids, making this O-ring a practical sealing solution for hydraulic, pneumatic, and fluid-handling assemblies. Licensed plumbers, HVAC technicians, and mechanical contractors commonly use Dash 325 O-rings when servicing valves, fittings, pumps, and manifold connections where a reliable static or low-dynamic seal is required.

This O-ring is suited for residential and light commercial plumbing, HVAC refrigerant-circuit components, pool and spa equipment fittings, and general industrial fluid systems. Typical applications include valve stem seals, union connections, pump housings, and filter-housing caps where a 1.5-inch ID seat groove is machined to standard Dash 325 dimensions. NBR material performs across a broad temperature range and handles water, oils, and many common refrigerants without excessive swelling or degradation.

Key Features

• Standard Dash 325 sizing for drop-in replacement in any groove machined to that specification
• 1.5-inch inside diameter with a 3/16-inch round cross-section thickness
• Nitrile Butadiene Rubber construction resists petroleum oils, hydraulic fluids, and water
• Round cross-section profile ensures consistent groove contact and even compression
• Inch measurement system dimensioning for straightforward specification matching

Compatibility

Designed as a standard Dash 325 O-ring replacement for any valve, fitting, pump, or housing that uses a Dash 325 groove dimensioned to 1.5-inch inside diameter and 3/16-inch cross-section in the inch measurement system.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanical technician. Depressurize and drain the system, or recover refrigerant per EPA Section 608 requirements, before removing any fitting or component containing the O-ring. Lubricate the O-ring lightly with a compatible fluid or O-ring lubricant before seating to prevent twisting or tearing during assembly. Do not use petroleum-based grease on systems where compatibility has not been verified.
