Value Collection BDNA-MP9974 O-ring Dash 009 Nitrile

Product Description

The VALUE COLLECTION BDNA-MP9974 is a Dash 009 O-ring manufactured from Nitrile Butadiene Rubber (Buna-N) for use in fluid and gas sealing applications across plumbing, HVAC, and mechanical systems. It features a 7/32 inch inside diameter and a 1/16 inch cross-section thickness with a round cross-section profile. Buna-N compound provides solid resistance to petroleum-based oils, hydraulic fluids, and water, making this O-ring a reliable choice for service valves, fittings, and port connections. Licensed tradespeople and experienced technicians handling seal replacement or component rebuilding will find this a standard consumable for routine maintenance work.

This O-ring is suited for residential and light commercial applications where a Dash 009 standard-size seal is required. Common installation points include service valve stems, refrigerant fittings, water supply connections, and hydraulic port plugs. Its compact dimensions make it appropriate wherever a small-diameter, tight-tolerance elastomeric seal is called for. This part is sold individually but carries a minimum order quantity of 20 units, making it practical for stocking in a service van or shop parts inventory.

Installation Notes

Installation should be performed by a qualified technician familiar with the system being serviced. Always depressurize and isolate the relevant fluid or refrigerant circuit before removing or installing any sealing component. Inspect the seating groove for damage or debris before installing the new O-ring, and apply a compatible lubricant to the O-ring to ease installation and prevent tearing. Do not over-stretch the O-ring during installation.
