OVERVIEW

Precision Replacement for Industrial Gas Control

The ESAB (Victor) 21942 Pressure Adjustment Screw Assembly is a critical maintenance component designed specifically for the Victor R36 Series B line of heavy-duty gas regulators. In the field of industrial gas regulation, the ability to finely tune delivery pressure is paramount for both safety and process quality. Over time, the threads on adjustment screws can wear, or the knurled knobs can sustain damage from impact or heavy use in harsh environments. This genuine OEM replacement assembly restores the regulator's original tactile feedback and precision control, ensuring that operators can set pressures with confidence.

Manufactured to the exact tolerances of the original equipment, this assembly guarantees a seamless fit and proper engagement with the regulator bonnet and internal spring mechanism. Using non-OEM parts in high-pressure gas equipment can compromise safety and performance; therefore, utilizing the authentic 21942 assembly is essential for maintaining the integrity of your Victor equipment. The assembly features a robustly engineered screw shaft and a durable knurled handle, designed to provide adequate leverage for adjustment while resisting the wear and tear typical of welding and cutting operations.

This component is specifically identified for the "Series B" revision of the R36 regulator family. It is vital for maintenance personnel to verify the series letter of their equipment before installation to ensure compatibility. By replacing a damaged adjustment assembly promptly, facilities can extend the service life of their premium regulators, avoiding the significant capital expenditure of full unit replacement while maintaining compliance with safety standards.

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.
