This kit includes an American made gas lens, 3/32" (2.4mm) wedge style collet and insulator needed to mount on your torch. The gas lens included with this kit has been specially modified by Furick Cup to have a smooth groove for the mounting o-ring to sit in. Please note that some torches will require you keep your stock insulator.
