0730-0082 - Victor SR 450/460 Regulator Diaphragm Replacement Assembly

Get Your Regulator Back in the Game

There is nothing more frustrating in the shop than a regulator that won't hold a steady pressure. You set it to 10 PSI, turn your back, and suddenly it's creeping up to 20, or the needle is bouncing every time you trigger the torch. These are classic signs of a worn-out diaphragm. The Victor 0730-0082 Diaphragm Assembly is the fix you need for your trusty Victor SR 450 or SR 460 regulator. These heavy-duty regulators are built like tanks and can last a lifetime, but the internal soft parts eventually wear out. Don't throw away a high-quality brass regulator just because the diaphragm is tired; rebuild it with this genuine Victor part and get it working like the day you bought it.

Replacing the diaphragm is a smart move for any welder who values consistency. A bad diaphragm can cause "starvation" at the weld puddle or an unstable cutting flame, leading to sloppy work and wasted gas. This assembly is the exact part used by the factory, meaning it fits perfectly without any guessing games. It is designed to handle the high pressures and rugged use that the SR series is known for. Whether you are running oxygen, acetylene, or inert shielding gases, ensuring your regulator's internals are in top shape is key to safe and efficient work.

Installation involves disassembling the regulator bonnet, removing the old assembly, and carefully seating the new one. It is a straightforward job for those experienced with equipment repair, and it saves you the massive cost of buying a brand-new heavy-duty regulator. Keep your gear running smooth and your arcs stable by swapping out that old, stiff diaphragm with a fresh 0730-0082. It’s cheap insurance against blown hoses and bad welds, keeping your focus where it belongs: on the metal.
