1407-0032 - Victor Replacement O-Ring .101 ID x .241 OD Buna-N

Technical Overview of the Victor 1407-0032 O-Ring

The Victor 1407-0032 is a precision-engineered O-ring designed specifically for maintenance and repair within the Victor family of oxy-fuel welding and cutting equipment. This component is manufactured from Buna-N (Nitrile Butadiene Rubber), a copolymer of butadiene and acrylonitrile. Buna-N is the standard elastomer for sealing applications requiring resistance to petroleum-based oils, fuels, and hydraulic fluids. Its material properties ensure that the O-ring maintains its structural integrity and sealing capability even when exposed to the harsh environments often found in industrial welding settings.

Dimensionally, this O-ring features an Internal Diameter (ID) of 0.101 inches, an Outer Diameter (OD) of 0.241 inches, and a cross-sectional width of 0.070 inches. These precise tolerances are critical for establishing a gas-tight seal in pressurized systems. In oxy-fuel applications, even microscopic imperfections in a seal can lead to gas migration, pressure loss, or hazardous leaks. By utilizing a genuine Victor part, operators ensure that the dimensional geometry matches the gland design of the equipment perfectly, providing appropriate compression and fill without extrusion.

The 1407-0032 is typically utilized in dynamic or static sealing points within torch handles, cutting attachments, or regulator assemblies where a small-diameter seal is required. The shore hardness of the Buna-N material is optimized to provide sufficient resilience to conform to mating surfaces while resisting permanent deformation (compression set) over time. Regular inspection and replacement of these O-rings are essential protocols in any preventative maintenance schedule for gas distribution equipment.

When installing this component, it is important to ensure that the mating surfaces are clean and free of burrs that could damage the elastomer. The use of an appropriate, compatible lubricant (compatible with both the O-ring material and the gas service) is recommended to facilitate installation and prevent twisting or shearing of the ring. This specific SKU ensures compliance with Victor's original manufacturing specifications.
