0730-0065 - Victor 0730-0065 Replacement Diaphragm Assembly for SR 450/460 Regulators

Get Your Regulator Back in the Fight

There is nothing more frustrating than a regulator that won't hold pressure steady. If you are noticing your delivery pressure creeping up when you stop cutting, or if your flame is fluctuating during a long pass, your diaphragm might be the culprit. The Victor 0730-0065 Diaphragm Assembly is the genuine fix for your heavy-duty Victor regulators, specifically the SR 450, SR 460, and SR 700 models. These regulators are workhorses, built to take a beating, but the internal rubber and metal components eventually wear out after years of service.

Don't risk your weld quality or your safety with a faulty regulator. A worn diaphragm can lead to inconsistent gas flow, making it impossible to set a neutral flame or maintain a stable arc. In worse cases, it causes pressure creep, which can damage downstream hoses and torches or blow out safety relief valves. Swapping out the old, tired diaphragm with this fresh OEM assembly brings your regulator back to factory specs. It restores that crisp, responsive feel when you adjust the knob and ensures your pressure stays exactly where you set it.

This isn't a generic knock-off; it's the real deal from Victor. It is designed to handle the high-flow demands of heavy cutting and heating applications. Whether you are running oxygen, acetylene, or inert shielding gases through your SR series regulator, this diaphragm is the heart of the system. Repairing your high-quality brass regulator is often far cheaper and better than buying a new, lower-quality unit. Keep your shop running smooth and your equipment safe with the correct replacement parts. Grab a 0730-0065 and get back to burning metal with confidence.
