Dimex Quartz, Gas Lens Collet Bodies are essential when using Dimex Elite Quartz Cups, providing a tight and secure seal. They are designed to work with stubby collets and utilise specifically positioned flow points and mesh screens to promote smooth efficient, turbulence free gas coverage. Using the Dimex Quartz, Gas Lens Collet Body also allows you to fit a 9/20 Series Gas Lens Ceramic Cup on a 17/18/26 Series Torch. This allows you to reduce the size and weight of your front end allowing you to get into tight, hard to reach spaces. Dimex gives you the ability to customise your front end to suit your specific needs so you can get the most out of your TIG Torch. P/N: CW4GL116NQ CW4GL332NQ CW4GL418NQ
