0730-0063 - Victor 350 Series Regulator Diaphragm and Seat Assembly

Stop the Creep and Fix Your Flow

Is your trusty Victor 350 regulator acting up? If you are noticing the delivery pressure gauge climbing when you aren't cutting or welding (a phenomenon known as "creep"), or if you hear a hiss coming from the regulator body, it is likely time for a rebuild. The Victor 0730-0063 Diaphragm Assembly is exactly what you need to get that heavy-duty workhorse back in the game. Don't risk your welds or your safety with a faulty regulator; swap out the internals with this genuine Victor part.

This isn't just a rubber disc; it's the complete diaphragm assembly featuring Victor's Unified Seat technology. This means you are replacing the two most critical wear points in your regulator at the same time. The seat is what stops the high-pressure gas from the tank, and the diaphragm is what tells the seat when to open. When either wears out, you get inconsistent flames and wasted gas. This kit makes the repair straightforward—pop the bonnet, swap the assembly, and you are ready to pressure test.

Designed for the 350 Series, this part fits the regulators found in many heavy-duty cutting outfits and shop setups. Using genuine OEM parts like this ensures that the fit is perfect and the materials can handle the pressure. Don't settle for generic knock-offs that might fail in a week. Rebuild it right with the 0730-0063 and get back to laying beads and cutting steel with the consistent flow control you expect from Victor equipment.
