Value Collection BDNA-MP9985 O-ring Dash 210 Nitrile Nbr

Product Description

The VALUE COLLECTION BDNA-MP9985 is a Dash 210 O-ring used to create static or dynamic fluid seals in plumbing, hydraulic, pneumatic, and HVAC applications. It features a 0.75 inch inner diameter and a 0.125 inch cross-section thickness with a round cross-section profile. Manufactured from Nitrile Butadiene Rubber (NBR, also known as Buna-N), this O-ring offers solid resistance to petroleum-based oils, fuels, and water, making it a dependable choice for sealing in a wide range of trade service environments. Licensed plumbers, HVAC technicians, and hydraulic system technicians routinely stock Dash 210 O-rings as a standard replacement seal.

This O-ring is suited for residential and light commercial systems where a 0.75 inch ID seal is required. Common applications include valve stems, fittings, pump housings, refrigeration service ports, and fluid-line connectors. The Buna-N compound performs reliably in contact with water, mineral oils, and many hydraulic fluids, making it a versatile keep-on-hand seal for general trade service work. Minimum order quantity is 10 units, sold in individual package quantity of 1.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or hydraulic system technicians depending on the application. Always depressurize and de-energize the system and relieve all fluid pressure before removing the old seal. Lightly lubricate the O-ring with a compatible fluid or assembly lubricant before seating to prevent tearing during installation. Inspect the groove for nicks, burrs, or corrosion that could compromise the seal before fitting the replacement ring.
