OVERVIEW

Genuine ESAB 22357 Replacement O-Ring for R-6700 Regulators

The ESAB 22357 is a specialized replacement O-ring designed explicitly for the maintenance and repair of the Victor / ESAB R-6700 series of high-flow regulators. In industrial gas distribution systems, the integrity of every seal is paramount to ensuring both safety and performance. The R-6700 series is renowned for its capacity to handle high volumes of gas flow, making the internal sealing components subject to significant pressure differentials and environmental stress. This O-ring serves as a critical barrier, preventing gas bypass and external leaks that could compromise the welding or cutting process.

Manufactured to strict OEM specifications, this O-ring is composed of high-grade elastomeric material selected for its compatibility with common industrial gases and its resilience against compression set. Over time, rubber components in regulators can dry out, crack, or deform due to temperature fluctuations and constant pressure. Replacing these seals with genuine ESAB parts ensures that the regulator maintains its factory-specified leak tightness. The 22357 O-ring provides a precise fit that generic substitutes cannot guarantee, reducing the risk of installation errors or premature failure.

For maintenance professionals and equipment technicians, using the correct part number 22357 is essential when overhauling R-6700 units. Whether performing a scheduled service or addressing a specific leak, this component restores the sealing capability of the regulator body or internal mechanism it is designed for. It is a small but vital investment in the longevity and safety of your oxy-fuel or inert gas equipment setup.

Key Technical Considerations:

  • Material Compatibility: Formulated to resist degradation from specified gas services used with R-6700 regulators.
  • Dimensional Accuracy: Engineered tolerances ensure a perfect seat within the regulator groove, preventing extrusion under pressure.
  • Safety Compliance: Utilizing OEM parts helps maintain compliance with safety standards regarding gas control equipment maintenance.

FAQ

This O-ring is specifically designed for the Victor / ESAB R-6700 series of high-flow regulators.

OEM O-rings like the 22357 are manufactured to exact dimensional tolerances and material specifications required for safe gas containment, whereas generic O-rings may fail under pressure or degrade chemically.

O-rings should be inspected regularly and replaced whenever the regulator is overhauled, or if signs of wear, cracking, or leakage are detected.

If the R-6700 regulator is rated for oxygen service, the OEM parts designed for it are typically compatible, but always ensure all parts are free of oil and grease during installation to prevent combustion hazards.

Common symptoms include audible hissing noises, the smell of leaking gas, pressure creep on the gauges, or visible damage to the seal during inspection.

Installation requires disassembling the specific section of the regulator where the O-ring resides. It should be performed by someone trained in gas equipment repair to ensure safety.

No, the O-ring is supplied dry. If lubricant is required by the service manual, ensure it is an approved lubricant for the specific gas service (e.g., oxygen-compatible lubricant).

It is made of a durable elastomer designed to withstand the pressures and environmental conditions typical of industrial gas regulation.
