0790-0033 - Victor SR250 and SR300 Regulator Rebuild Kit

Genuine Victor Maintenance for SR250 & SR300 Regulators

The Victor 0790-0033 Repair Kit is an essential maintenance item for owners of Victor SR250 and SR300 series regulators. These heavy-duty single-stage regulators are staples in the welding industry, renowned for their rugged construction and reliable performance. However, internal components such as seats and diaphragms are wear items that require periodic replacement to maintain safe operation. This comprehensive repair kit contains everything needed to perform a full overhaul, ensuring your regulator functions with the precision and safety you expect from the Victor brand.

Why Choose OEM Repair Kits?

When dealing with high-pressure compressed gases, there is no room for compromise. Genuine Victor repair kits are manufactured to the exact tolerances and material specifications of the original equipment. The seat assembly in this kit is designed to seal perfectly against the nozzle, preventing dangerous pressure creep that can damage downstream equipment or cause hose ruptures. The diaphragm is crafted from materials that maintain flexibility and sensitivity, allowing for accurate pressure adjustment even after years of use. Using non-OEM parts can compromise these safety features and void equipment warranties.

Signs Your Regulator Needs Repair

Knowing when to use the 0790-0033 kit is key to maintaining a safe shop environment. Common symptoms indicating a need for a rebuild include:

• Creep: The gauge pressure continues to rise after the torch valve is closed.
• Humming or Chattering: The regulator makes noise during operation, indicating internal vibration or instability.
• External Leaks: Gas is detected escaping from the bonnet or body connections.
• Inconsistent Pressure: The delivery pressure fluctuates during use, affecting flame quality.

This kit includes the seat assembly, diaphragm, slip ring, and necessary gaskets. It is designed for the SR250 and SR300 series, which are often found in heavy fabrication, oil and gas, and construction applications. By rebuilding your regulator with this kit, you ensure that your cutting and welding processes remain efficient and, most importantly, safe. Welders Supply Company recommends professional installation for all gas equipment repairs to ensure proper assembly and testing.
