MW18-CG - 18CG TIG Torch Insulator Gasket

Essential Maintenance for TIG Torches

Keep your TIG torch operating at peak performance with the MW18-CG Cup Gasket. Often overlooked, this small white insulator plays a massive role in the quality of your welds. It is the interface between your torch's collet body and the alumina nozzle, responsible for sealing the shielding gas path. A compromised gasket can lead to turbulence in the gas flow, resulting in poor coverage, oxidation, and unstable arcs. This replacement part is built to industry-standard specifications (referencing part number 18CG) and is a direct fit for WP-17, WP-18, and WP-26 model torches.

The MW18-CG is specifically engineered for setups utilizing standard collet bodies. It is not intended for gas lens setups (which typically require a different insulator), making it the go-to choice for general-purpose TIG welding applications. The high-quality polymer construction offers excellent dielectric strength and heat resistance, protecting your torch head from excessive heat buildup and electrical shorts.

Every welder's toolbox should contain spare cup gaskets. Because they are subjected to constant heating and cooling, they are consumable items that degrade over time. A fresh gasket ensures that your ceramic cup screws on securely and seals perfectly. Whether you are welding in a shop environment or out in the field, having a reliable MW18-CG gasket on hand means you can fix a leak instantly and get back to laying beads. Compatible with Weldcraft, Miller, Lincoln, and other major TIG torch brands using the 17/18/26 form factor.
