34Z50 - Arcair K4000 Valve and Lever Screw Replacement

Genuine Arcair 34Z50 Screw for K4000 Valve & Lever Assembly

Maintain the reliability and performance of your carbon arc gouging equipment with the Arcair 34Z50 Screw. This specific fastener is a critical replacement component designed exclusively for the K4000 (K-4000) Angle-Arc Gouging Torch. As a genuine OEM part manufactured by Arcair (an ESAB brand), it guarantees the precise thread pitch, length, and material strength required to securely hold the valve and lever mechanism in place.

In the demanding environment of heavy industrial gouging, torches are subjected to extreme heat, vibration, and mechanical stress. The valve and lever assembly is the control center for the high-pressure air stream that clears away molten metal. If the securing screw becomes loose, stripped, or lost during maintenance, the lever may fail to engage the air valve correctly, leading to inefficient gouging or safety hazards. The 34Z50 screw restores the structural integrity of this assembly, ensuring the lever pivots smoothly and the valve actuates with precision.

Professional welders and fabricators understand that using non-standard hardware in high-amperage torches can lead to premature failure. This screw is built to withstand the rigors of daily shop use. Whether you are performing a complete rebuild of your K4000 torch or simply replacing a lost fastener, this part ensures your equipment returns to factory specifications. It is an essential item to keep in your preventative maintenance kit to minimize downtime.
