High-Purity Gas Solenoid Upgrade Kit for Miller® Diversion™ 165, 180 & Hobart® EZ-TIG 165i TIG Machines.

The JW Signature Series High-Purity Gas Supply Kit™ is an end-to-end gas supply upgrade kit from the regulator to the front panel of your machine.

We engineered it with high-quality stainless steel compression fittings, high density, non-permeable gas tubing and precision stainless steel gas solenoid.

The kit includes everything needed for the installation, and can be installed in minutes. 

What Problem Does it Solve?The Gas Solenoid located under your TIG machines cover is "out of sight & out of mind".

The fact is, those solenoids are proven to leak shield gas and draw moisture and atmosphere contamination into your TIG torch! And because it's located "under the hood", you can't easily leak test the gas delivery path to verify the integrity of the system.

Why Does it Matter?Factory installed permeable rubber hoses, low-cost plastic gas solenoids and spring type hose clamps all lead to gas leaks, moisture and atmosphere contamination.

Kit Includes:

  • High-purity gas solenoid with whip lead & blade connectors
  • Stainless steel fittings and hose connectors
  • High density, non-permeable gas supply hose
  • Stainless Steel male 1/8” NPT to ¼” Compression
  • Brass Male 1/8” NPT to 5/8” x 18 right hand female coupler

All components are made in U.S.A.
