Value Collection BDNA-MP9991-1 O-ring Dash 216 Buna-n

Product Description

The VALUE COLLECTION BDNA-MP9991-1 is a Dash 216 O-ring used to create reliable fluid and pressure seals in plumbing, HVAC, and mechanical systems. Constructed from Nitrile Butadiene Rubber (Buna-N), it features a round cross section with an inside diameter of 1-3/16 inches and a thickness of 1/8 inches. Buna-N compound offers solid resistance to petroleum-based oils, fuels, and water, making it a widely used elastomer choice across trade applications. This O-ring is installed by plumbers, HVAC technicians, and mechanical service professionals wherever a leak-free static or dynamic seal is required at standard service conditions.

This O-ring is suited for use in residential and light commercial systems including valves, pumps, fittings, manifolds, and fluid-handling assemblies where a Dash 216 size seal is specified. Its Buna-N material is compatible with water, hydraulic oil, and many petroleum-based fluids commonly found in HVAC refrigerant-side accessories, plumbing shutoffs, and pool equipment connections. Sold individually with a minimum order quantity of 10 units per order.

Compatibility

Designed as a standard Dash 216 replacement O-ring for use in valves, pumps, fittings, and fluid-handling components that call for a 1-3/16 inches ID, 1/8 inches thick Buna-N seal.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanical service professional. Always shut off fluid supply and depressurize the system before removing or installing any O-ring. Inspect the mating groove for scoring or debris before seating the new O-ring, and apply a compatible lubricant to ease installation and prevent tearing. Do not overstretch the O-ring during installation.
