10 x 17/18/26 to 9 series gas lens converter bodies.
Needed to run all of our STUBBY and MEGA cups in your 17/18/26 series torches.
Running a smaller cup on a bigger torch means less weight in your hand. The 9/20 series cups and gas lenses are more than 1/2 the weight of regular 17/18/26 consumables!
Also helps getting into tighter areas :).
