Value Collection BDNA-MP9975 O-ring Dash 010 Buna-n

Product Description

The VALUE COLLECTION BDNA-MP9975 is a Dash 010 O-ring sealing element manufactured from Nitrile Butadiene Rubber, also known as Buna-N. It features a 0.25 inch inside diameter and a 0.0625 inch cross-section thickness with a round cross-section profile. Buna-N is a synthetic rubber compound widely chosen in fluid-handling applications for its resistance to petroleum-based oils, hydraulic fluids, and fuels. Plumbers, HVAC technicians, and mechanical contractors regularly use O-rings of this type when servicing fittings, valves, and hydraulic assemblies where a reliable, low-profile seal is required.

This O-ring is suited for use in residential and light commercial plumbing systems, HVAC refrigerant and hydraulic circuits, pneumatic fittings, and general industrial fluid connections. The Dash 010 designation is a standard sizing reference used across a broad range of OEM and aftermarket fittings and valve bodies, making it a common stock item for service vehicles and shop inventories. Its small form factor fits tight-clearance grooves where larger O-rings cannot seat properly.

Key Features

• Buna-N (Nitrile Butadiene Rubber) material offers strong resistance to petroleum-based oils and hydraulic fluids
• Round cross-section profile seats evenly in standard O-ring grooves
• Dash 010 sizing for compatibility with widely used OEM and aftermarket fittings
• 0.25 inch inside diameter and 0.0625 inch thickness for tight-clearance installations
• Lightweight construction at 0.01 pounds per unit

Compatibility

Designed as an OEM-style replacement O-ring for Dash 010 groove applications in plumbing, HVAC, pneumatic, and general industrial fluid-handling assemblies.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or mechanical contractors. Always depressurize and drain the relevant system before replacing O-rings, and ensure the seating groove is clean and free of debris or old material. A light application of a compatible lubricant, such as a silicone-based or system-compatible grease, aids proper seating and reduces the risk of tearing during assembly. Do not overstretch the O-ring during installation, as this can compromise the seal.
