Value Collection BDNA--9995-2 O-ring Dash 206 Nbr

Product Description

The VALUE COLLECTION BDNA--9995-2 is a Dash 206 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 0.5 inches inside diameter and 0.125 inches thick, with a durometer hardness rating of 70 Shore A. NBR compound provides reliable resistance to petroleum-based fluids, making this O-ring well suited for sealing applications in hydraulic, pneumatic, plumbing, and refrigeration systems. Licensed plumbers, HVAC technicians, and maintenance professionals install this type of O-ring as a sealing element at fittings, valves, and connectors where fluid or gas containment is required.

This Dash 206 O-ring is appropriate for residential and light commercial applications wherever a 0.5-inch ID round-cross-section seal is specified. Common install scenarios include valve stem seals, union fittings, and pump connections in water, oil, or air service lines. The 70 durometer rating indicates a medium hardness, balancing compressibility and resistance to extrusion under moderate operating pressures. This part is sold individually and must be ordered in multiples of 25 units minimum.

Key Features

• Dash 206 standard sizing: 0.5 inches ID, 0.125 inches thick
• Nitrile Butadiene Rubber (NBR) construction for resistance to petroleum-based fluids
• 70 Shore A durometer for medium hardness and reliable compression sealing
• Round cross section for consistent groove seating and even load distribution
• Inch measurement system for straightforward sizing in standard plumbing and HVAC applications

Compatibility

Designed as a standard Dash 206 replacement O-ring for use in any application requiring a 0.5-inch ID, 0.125-inch thick NBR round-cross-section seal.

Installation Notes

Installation of O-rings is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always shut off fluid or gas supply and depressurize the system before removing the old seal. Lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent tearing during installation. Do not overstretch or twist the O-ring when placing it into the groove.
