1407-0187 - Victor Replacement O-Ring Seal 2.989 ID x 3.125 OD Buna-N

Victor 1407-0187 Replacement O-Ring (Buna-N)

The Victor 1407-0187 is a specialized replacement O-ring designed for maintenance and repair of Victor gas equipment. Manufactured from high-quality Buna-N (Nitrile rubber), this seal offers excellent resistance to petroleum-based oils, aliphatic hydrocarbons, and water, making it a standard choice for general-purpose sealing applications within industrial environments. Proper sealing is critical in oxy-fuel and gas regulation systems to prevent leaks, ensure pressure stability, and maintain safe operation.

This O-ring features precise dimensions to ensure a correct fit within the designated groove of the equipment. With an Inner Diameter (ID) of 2.989 inches and an Outer Diameter (OD) of 3.125 inches, it is a relatively large seal typically found in larger regulator bodies, torch assemblies, or machine torch barrels. The cross-sectional width is 0.070 inches, a standard size that provides adequate compression for a tight seal without over-stressing the material.

Using genuine Victor replacement parts like the 1407-0187 ensures that the dimensional tolerances and material properties match the original engineering specifications of your equipment. Generic O-rings may vary slightly in durometer or size, leading to potential leak paths or premature failure. This Buna-N O-ring is designed to withstand the mechanical wear and environmental conditions typical of welding and cutting operations.
