0740-0131 - Victor Regulator Seat and Stem Replacement Kit

Stop the Creep and Weld with Confidence

Is your regulator gauge climbing even when you aren't cutting or welding? That's called "creep," and it's a sure sign that your internal seat is worn out. Don't risk blowing a hose or damaging your diaphragm—fix it right with the Victor 0740-0131 Seat & Stem Assembly. This is the genuine replacement part you need to get your trusty Victor regulator back to working like the day you bought it.

We know that your Victor SR 450 or SR 460 regulator is a workhorse. It takes a beating in the shop and on the truck, but eventually, the internal seat needs a refresh. This assembly drops right in to replace the old, worn-out valve stem. It seals tight against the nozzle, stopping leaks and ensuring your pressure stays exactly where you set it. No more constantly adjusting the knob or worrying about pressure spikes ruining your flame setting.

Swapping out the seat and stem is a standard maintenance procedure that can save you the cost of buying a brand-new regulator. By using this authentic Victor part, you ensure that everything fits perfectly without any guessing games. Whether you are running oxygen, acetylene, or mixed gases, keeping your regulator internals in top shape is key to safe and efficient work. Grab this assembly, perform the swap, and get back to laying beads with steady, reliable gas flow.
