OVERVIEW

Get Your Regulator Back in the Fight

There is nothing more frustrating than reaching for your regulator to dial in the perfect flame, only to find the adjustment knob is bent, stripped, or missing entirely. The ESAB (Victor) 21942 Pressure Adjustment Screw Assembly is the exact part you need to fix your Victor R36 Series B regulator and get back to work. We know that in a busy shop or on a rough job site, gear takes a beating. Regulators get knocked over, things fall on them, and eventually, the adjustment screw can fail. Don't try to rig it with pliers or makeshift handles—that's a safety hazard and a pain in the neck to use.

This is the genuine article, the same knob and screw assembly that came on your regulator when it was brand new. It features that classic knurled texture that makes it easy to grip, even when you've got your heavy welding gloves on. It threads in smoothly, letting you dial in your PSI exactly where you need it for cutting, heating, or welding. Keeping your pressure steady is the key to a clean cut and a good weld, and you can't do that with a wobbly or sticky adjustment knob.

Swapping this part out is a straightforward repair that saves you from having to trash a perfectly good high-flow regulator. Just make sure you check your regulator body—this one is specifically for the Series B version of the R36. If you're running Victor gas gear, keep it 100% Victor with this replacement assembly. It’s built tough, it fits right the first time, and it keeps your oxy-fuel setup running safely and efficiently.

FAQ

This assembly is designed specifically for the Victor R36 Series B regulators. Please check the series designation on your regulator body before ordering.

No, this item is typically the adjustment screw and knob assembly only. The internal spring and other bonnet components are sold separately.

Regulator parts are often series-specific due to changes in thread pitch or bonnet design. It is recommended to use this part only for Series B as specified to ensure safety.

Yes, this is a genuine OEM replacement part manufactured by ESAB (parent company of Victor Technologies).

If the stripping is on the adjustment screw itself or the knob is broken, yes. If the threads inside the regulator bonnet are stripped, you may need a new bonnet or regulator.

Unscrew the old assembly completely (counter-clockwise) until it comes out of the bonnet. Inspect the threads, then thread the new assembly in. Ensure the system is depressurized before performing maintenance.

The assembly typically features a metal screw with a durable metal or composite knurled knob, designed for industrial durability.

'Knurl AY' stands for Knurled Assembly, referring to the textured grip pattern on the knob that allows for hand adjustment.
