54N01 - 54N01 Gas Lens Insulator for WP-17, WP-18, WP-26 TIG Torches (2-Pack)

Unlock the Full Potential of Your TIG Torch

Are you looking to upgrade your TIG welding game with a gas lens kit? Don't forget the most important adapter piece: the 54N01 Gas Lens Insulator. This small but mighty component is the key to converting your standard WP-17, WP-18, or WP-26 torch into a precision welding instrument. If you are switching from a standard collet body to a gas lens to get that buttery-smooth gas coverage and colorful welds, you absolutely need this insulator to make it all fit together.

Gas lenses are famous for smoothing out the flow of argon, creating a laminar stream that protects your tungsten and weld puddle far better than standard setups. However, gas lenses are physically larger than standard collet bodies. The 54N01 insulator replaces your stock white gasket (18CG) and provides the correct spacing and seal for the gas lens. Without it, your cup won't screw on, and your gas will leak, ruining the very shielding you are trying to improve.

Our 54N01 insulators are built tough. They resist the extreme heat of TIG welding without becoming brittle or cracking prematurely. They are designed to fit universally on all 3-Series torches (17/18/26), regardless of whether you are using a Miller, Lincoln, or CK torch. Sold in convenient packs of two, you can keep a spare in your toolbox so you never have to stop welding due to a lost or damaged part. Whether you are welding stainless steel exhaust systems or aluminum intake manifolds, ensure your torch is set up for success with these essential insulators.
