Value Collection BDNA--9995-1 O-ring Dash 205 Nbr 7/16 in Id

Product Description

The VALUE COLLECTION BDNA--9995-1 is a Dash 205 O-ring with a 7/16-inch inside diameter and a 1/8-inch cross-section thickness. Molded from Nitrile Butadiene Rubber (NBR) with a 70 durometer hardness rating, it delivers reliable resistance to petroleum-based fluids, making it a standard choice for hydraulic, pneumatic, and fluid-handling assemblies. The round cross-section profile seats consistently in standard O-ring grooves machined to Dash 205 dimensions. Licensed plumbers, HVAC technicians, and industrial maintenance mechanics routinely stock this size for valve, fitting, and pump seal applications.

This O-ring is suited for residential and commercial plumbing systems, HVAC refrigerant and fluid circuits, pool and spa equipment, and general-purpose pneumatic or hydraulic assemblies where a Dash 205 NBR seal is specified. The NBR compound performs across a broad range of operating temperatures and resists degradation from oils, fuels, and water-based fluids encountered in trade service work. It is sold individually, with a minimum order quantity of 25 units.

Key Features

• Dash 205 standard sizing: 7/16-inch inside diameter, 1/8-inch cross-section thickness
• Nitrile Butadiene Rubber (NBR) compound resists petroleum-based oils, hydraulic fluids, and water
• 70 durometer hardness provides firm, consistent compression in standard O-ring grooves
• Round cross-section profile for uniform seating and reliable static or dynamic sealing
• Inch-system dimensioning compatible with standard SAE and AN O-ring groove specifications

Compatibility

Designed as an OEM-style replacement or service seal for any application requiring a Dash 205 NBR O-ring per inch-system groove standards in plumbing, HVAC, pool, or hydraulic equipment.

Installation Notes

Power down or depressurize the system completely before replacing any O-ring seal. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before installation to prevent tearing during assembly. Avoid rolling or twisting the ring into the groove; seat it evenly by hand. Verify groove dimensions match Dash 205 specifications before installation to ensure proper compression and sealing.
