1407-0255 - Victor Buna-N O-Ring Size -005

Precision Sealing for Victor Gas Equipment

The Victor 1407-0255 O-Ring is a critical replacement component designed specifically for the maintenance and repair of Victor oxy-fuel welding and cutting apparatus. Manufactured to exact OEM specifications, this O-ring ensures the integrity of gas seals within regulators, torches, and cutting attachments. The part is constructed from Buna-N (Nitrile rubber), a material widely selected in the industrial sector for its excellent physical properties and chemical resistance.

With a 70 Durometer hardness rating, this O-ring offers the ideal balance between pliability for effective sealing and rigidity for pressure resistance. The dimensions of this seal—0.101-inch Inner Diameter (ID), 0.241-inch Outer Diameter (OD), and 0.070-inch width—correspond to the standard -005 O-ring size. This precise sizing is essential for maintaining the correct compression ratio within the gland, preventing both low-pressure leakage and high-pressure extrusion.

Buna-N is the standard material for general-purpose sealing rings due to its exceptional resistance to petroleum-based oils, fuels, water, and many other chemicals. In the context of welding equipment, this material choice ensures that the seal remains intact even when exposed to residual lubricants or environmental contaminants found in industrial workshops. Regular inspection and replacement of O-rings are vital for the safe operation of gas equipment; a compromised O-ring can lead to gas migration, pressure loss, or hazardous leaks. By choosing the genuine Victor 1407-0255, technicians ensure compatibility and safety standards are met for their Victor equipment.

This component is suitable for a variety of applications within the Victor product line. It is commonly found in internal regulator assemblies, torch valve stems, and connection points where a static or dynamic seal is required. When installing, ensure the mating surfaces are clean and free of burrs to prevent damage to the new seal.
