0740-0102 - Victor SR400 Series LP Regulator Seat and Stem Kit

Restore Precision to Your LP Gas Regulation

The Victor 0740-0102 LP Seat & Stem Assembly is a critical replacement component designed to maintain the safety and efficiency of your Victor heavy-duty regulators. When dealing with fuel gases like Liquid Propane (LP) or Natural Gas, the integrity of your pressure regulation equipment is paramount. Over time, the internal seat of a regulator can wear down due to friction, debris, or general aging, leading to performance issues such as pressure creep or leaking. This genuine Victor part allows you to overhaul your equipment and return it to factory-standard performance.

Specifically engineered for the SR 400, SR 450, and SR 700 series regulators, this assembly is constructed to withstand the specific chemical properties of LP gas. Using incorrect parts or generic substitutes in gas apparatus can lead to seal degradation and safety hazards. Victor Equipment is renowned for its high-quality brass construction and precision machining, ensuring that this stem fits perfectly within the regulator body to provide a tight, reliable seal.

Regular maintenance of your gas equipment is essential for any industrial or welding workshop. If you notice your regulator gauge rising when the torch valves are closed (a phenomenon known as creeping), it is often a sign that the seat assembly needs replacement. By installing the 0740-0102, you ensure consistent flow rates and safe operation for heating, cutting, and brazing applications. Trust Josef Gas to provide authentic Victor components that keep your operations running smoothly and safely.
