Value Collection BDNA--9995-5 O-ring Dash 209 Nbr

Product Description

The VALUE COLLECTION BDNA--9995-5 is a Dash 209 O-ring used to create static or dynamic fluid seals in plumbing, HVAC, and mechanical systems. It measures 11/16 inches inside diameter with a 1/8 inch cross-section thickness and a round cross-section profile. The compound is Nitrile Butadiene Rubber (NBR) with a 70 durometer hardness rating, which gives it solid resistance to petroleum-based oils, hydraulic fluids, and water. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of O-ring as a replacement seal in valves, fittings, pumps, and fluid-handling components.

This O-ring is suited for residential and light commercial applications where an inch-system Dash 209 seal is required. Common install scenarios include replacing worn or cracked seals in ball valves, service valves, pump housings, and refrigeration fittings. The NBR compound performs across a broad range of operating temperatures and is a standard choice where oil or water exposure is expected. Sold individually per package, with a minimum order quantity of 25 units.

Key Features

• Dash 209 standard sizing: 11/16 inches inside diameter, 1/8 inch thickness
• Nitrile Butadiene Rubber (NBR) compound resists petroleum oils, hydraulic fluid, and water
• 70 durometer hardness provides firm, reliable sealing under compression
• Round cross-section for consistent contact and even load distribution
• Inch-system measurement for compatibility with standard U.S. hardware

Compatibility

Designed as a standard Dash 209 inch-series O-ring replacement for valves, fittings, pumps, and fluid-handling assemblies that accept a 70-durometer NBR seal with 11/16 inch inside diameter and 1/8 inch cross-section.

Installation Notes

Licensed plumbers and HVAC technicians typically install O-rings of this type during valve rebuilds, fitting replacements, or pump seal service. Shut off all fluid supply and relieve system pressure before removing any component containing this seal. Inspect the seating surface for scoring or debris before installing the new O-ring. Avoid pinching or twisting the O-ring during installation to prevent early seal failure.
