0731-0018 - Victor 0731-0018 Replacement Diaphragm for VTS Series Regulators

Restore Your Regulator's Performance

If your trusted Victor VTS regulator has started acting up—maybe the pressure is creeping up when the torch is off, or you hear a faint hissing sound from the bonnet—it might be time to replace the diaphragm. The Victor 0731-0018 Diaphragm Assembly is the genuine repair part you need to get your heavy-duty two-stage regulator back in fighting shape. We know that a good regulator is an investment, and tossing a high-quality Victor VTS unit just because of a worn-out rubber part doesn't make sense. This replacement assembly allows you to fix the heart of the regulator and get back to work with confidence.

Regulator diaphragms take a beating over years of service. They flex thousands of times as you open and close valves and adjust settings. Eventually, they can stiffen, crack, or warp, which ruins the regulator's ability to hold a steady flame or flow rate. This specific part, the 0731-0018, is designed to fit perfectly inside Victor VTS 450 and VTS 700 series regulators. Because it is a genuine Victor part, you don't have to worry about it being slightly the wrong size or made of inferior material that will fail in a month. It drops right in during your rebuild process, restoring the sensitive control you expect from a two-stage unit.

Safety is the number one priority when dealing with compressed gases. A compromised diaphragm isn't just an annoyance; it can be a safety hazard if it leads to gas leaks or uncontrolled pressure delivery. By swapping out the old assembly with this factory-fresh replacement, you ensure that your equipment is safe for you and your shop. Whether you are running an oxy-fuel cutting rig or a precision TIG setup, keeping your regulator in top condition is key to quality welds and cuts. Don't settle for 'close enough' aftermarket parts when it comes to gas control; stick with the original Victor 0731-0018 to keep your gear running like new.
