OVERVIEW

Get Your Victor Regulator Back in Action

When your trusty Victor regulator starts acting up—maybe the pressure is creeping up when the torch is off, or the flow feels inconsistent—it's often the diaphragm that needs attention. The Victor 0730-0033 Diaphragm Assembly is the genuine repair part you need to fix your SR 450 or SR 460 series regulator and get back to work safely.

We know that in the shop or out in the field, you rely on your gear to work right every time. A failing regulator isn't just annoying; it's a safety hazard and a quality killer. Instead of tossing a high-quality heavy-duty regulator in the scrap bin, you can rebuild it with this authentic Victor assembly. It’s the exact same part that came inside the regulator when it was new, so you know it’s going to fit perfectly and hold up to the demands of daily use.

Swapping out the diaphragm is a standard maintenance procedure for professional gas apparatus repair. By choosing genuine Victor parts, you ensure that the tension, flexibility, and sealing properties are exactly what the engineers intended. Don't risk your welds or your safety with generic knock-offs; stick with the brand that built the regulator in the first place.

Why Choose Genuine Victor Parts?

  • Safety First: Ensure your gas equipment holds pressure correctly and doesn't leak.
  • Cost Effective: Repairing a high-end regulator is much cheaper than buying a new one.
  • Reliability: Trust in the durability of Victor's manufacturing for long-lasting repairs.

FAQ

This diaphragm assembly is designed for Victor SR 450, SR 460, and SR 700 series regulators.

Common signs include 'creep' (outlet pressure rising when the torch is closed), erratic pressure delivery, or audible leaks from the regulator body.

Yes, this is a genuine OEM Victor Technologies part, ensuring exact fit and performance specifications.

No, it is specifically engineered for the internal geometry of Victor SR series regulators and is not universal.

Typically, the diaphragm assembly includes the diaphragm plate and material. The main adjustment spring is usually a separate component.

It requires disassembly of the regulator bonnet. While straightforward for trained technicians, gas equipment repair should always be performed by qualified personnel due to safety risks.

The material is specified by Victor for the SR 450/460 series to handle high-pressure applications, often involving stainless steel or specialized elastomers depending on the specific sub-model revision.

If the leak is coming from the diaphragm seal or if the diaphragm is ruptured, yes. However, leaks can also occur at the seat assembly or o-rings, so a full inspection is recommended.
