34074 - Replacement Valve Stem for 26FV TIG Torch

Restore Precision Gas Control to Your TIG Torch

The VALVE STEM HW-26FV (Part #34074) is an essential replacement component designed to maintain the functionality of your air-cooled TIG welding torch. For welders who rely on the flexibility and manual control of "V" (Valve) or "FV" (Flex Valve) style torches, the integrity of the gas valve is paramount. Over time, the internal seals of a valve stem can degrade, or the threads can wear, leading to gas leaks or difficulty in turning the knob. This high-quality replacement assembly allows you to restore your torch to factory performance without the expense of purchasing a completely new torch body.

Engineered specifically for the HW-26FV and compatible WP-26FV series torches, this valve stem features a precision-machined brass body that seats perfectly within the torch handle. The assembly comes pre-fitted with durable rubber O-rings that provide a positive, airtight seal, preventing costly shielding gas wastage and ensuring that your weld pool remains protected from atmospheric contamination. The control knob is designed with a knurled texture, making it easy to grip and adjust even while wearing heavy welding gloves. Whether you are working in a shop environment or out in the field where a gas solenoid is not available, this valve stem ensures you have reliable, on-demand control over your argon flow.

Installation is straightforward and requires no special tools. Simply unscrew the old, worn-out stem, check the torch body for debris, and thread in the new 34074 unit. It is compatible with a wide range of 17-series and 26-series torches that utilize the standard manual gas valve design. By keeping a spare valve stem in your maintenance kit, you ensure that a minor component failure never stops your production or project.
