Value Collection BDNA--9994-2 O-ring Dash 327 Nbr

Product Description

The VALUE COLLECTION BDNA--9994-2 is a Dash 327 O-ring used to create reliable fluid and pressure seals in a wide range of plumbing, HVAC, and mechanical service applications. Manufactured from Nitrile Butadiene Rubber (NBR) with a 70 durometer hardness rating, this O-ring offers solid resistance to oils, fuels, and common hydraulic fluids. It measures 1-3/4 inches inside diameter with a 3/16 inch cross-section thickness and features a round cross-section profile. Licensed plumbers, HVAC technicians, and mechanical contractors use NBR O-rings when servicing valves, fittings, pumps, and fluid handling assemblies where petroleum-based fluid contact is expected.

This O-ring is suited for residential and light commercial service work where inch-standard sealing components are required. The Dash 327 designation follows standard AS568 sizing, making it straightforward to identify and specify as a replacement seal in pumps, valves, compressors, and manifold connections. It is packaged individually but carries a minimum order quantity of 25 units, making it practical for stocking in a service van or shop inventory for recurring seal replacement jobs.

Key Features

• Nitrile Butadiene Rubber (NBR) construction resists petroleum-based oils, hydraulic fluids, and common refrigerants
• 70 durometer hardness provides a firm yet compressible seal suitable for most standard-pressure applications
• 1-3/4 inch inside diameter with 3/16 inch thickness per Dash 327 inch-standard sizing
• Round cross-section profile for consistent compression and reliable sealing in standard O-ring grooves
• Inch-system dimensions for straightforward replacement in domestic equipment and fittings

Compatibility

Designed as an OEM-style replacement seal for inch-standard Dash 327 O-ring applications in plumbing, HVAC, pump, and fluid handling assemblies.

Installation Notes

O-ring replacement should be performed by a qualified plumber, HVAC technician, or mechanical contractor. Always depressurize and isolate the system before removing the existing seal, and inspect the groove and mating surfaces for damage or scoring before installing the new ring. Apply a compatible O-ring lubricant to ease installation and reduce the risk of tearing the ring during assembly. Do not stretch or twist the O-ring during installation.
