OVERVIEW

Stop Regulator Creep with the Genuine 34Y01 Seat

Is your regulator pressure climbing when you aren't cutting? That's called "creep," and it's usually a sign that your valve seat is shot. Don't risk a blowout or poor cut quality—fix it right with the ESAB 34Y01 Screw Clamping Valve Seat Assembly. This is the genuine OEM part for your trusty Oxweld or Purox regulator, designed to get your gear back to factory specs so you can focus on the job, not the gauge.

The valve seat is the most hardworking part of your regulator, constantly opening and closing against high cylinder pressure. When it wears out, you lose control of your flame. The 34Y01 is built tough to handle the rigors of daily shop use. It fits popular workhorses like the Oxweld R-72, R-76, and R-77. Swapping out the seat is a standard maintenance procedure that can save you the cost of buying a brand-new regulator.

Don't settle for sketchy aftermarket parts when it comes to gas safety. This ESAB assembly ensures a perfect seal and smooth flow control. Whether you are running oxygen, acetylene, or propane, keeping your regulator internals fresh is key to consistent welds and clean cuts. Grab a 34Y01 seat today and keep your station running safely and efficiently.

FAQ

The valve seat creates a seal against the nozzle to control the flow of gas from the high-pressure inlet to the low-pressure chamber. It is essential for maintaining the set delivery pressure.

The 34Y01 is primarily designed for Oxweld R-Series regulators, such as the R-72, R-76, and R-77, as well as select Purox models.

The most common sign is 'creep,' where the delivery pressure gauge reading slowly rises after you close the torch valve. This indicates the seat is not sealing completely.

Yes, this is a genuine ESAB OEM part. ESAB owns the Oxweld and Purox brands and manufactures their replacement components.

Regulator repair should only be performed by qualified technicians or individuals trained in gas apparatus repair due to the safety risks associated with high-pressure gas.

No, this is typically just the valve seat assembly. The nozzle is usually a separate component, though they interact directly.

Humming or vibration can sometimes be caused by a worn seat or internal resonance. Replacing the seat assembly often resolves this issue.

It typically consists of a brass body with a specialized synthetic rubber or polymer insert designed to withstand high gas pressures and resist chemical degradation.
