0730-0001 - Victor Stainless Steel Diaphragm Assembly for SR 450/460/700 Regulators

Restore Your Regulator to Factory Performance

Is your trusty Victor regulator acting up? If you are noticing the delivery pressure gauge creeping up when your torch is off, or if the flow feels inconsistent during a cut, your diaphragm might be the culprit. The Victor 0730-0001 Diaphragm Assembly is the genuine OEM solution to get your heavy-duty gear back in the fight. Built for the legendary SR 450, SR 460, and SR 700 series regulators, this isn't a cheap knock-off; it's the same stainless steel heart that came with your regulator when it was brand new.

Why stainless steel? Because in heavy industrial work, durability is everything. Stainless steel diaphragms offer a crisp, responsive feel when adjusting pressure and handle the stress of high-flow applications far better than rubber alternatives. This assembly is designed to withstand the rigors of daily shop use, whether you are running a heavy scrap cutting operation or precision welding with inert gases. Replacing a worn diaphragm is often all it takes to save a regulator that would cost hundreds of dollars to replace entirely.

This kit includes the complete diaphragm assembly, meaning the metal diaphragm is already securely mounted with the center hardware, ready to drop into the regulator body. While regulator repair requires care and cleanliness—especially for oxygen service—having the right part makes the job significantly easier. Don't compromise your weld quality or shop safety with worn-out equipment. Invest in the Victor 0730-0001 Diaphragm Assembly and ensure your gas delivery system is as reliable as your welding skills. Keep your flame steady and your pressure accurate with genuine Victor parts.
