Genuine Ckworldwide gas lens (9,20 torch)

Is an American made gas lens needed to fit every Furickcup except the ally 5 to a 9 or 20 torch. It is for a 3/32-2.4mm size tungsten but will a accommodate a 1/16-1.6 mm tungsten if the user installs a 1/16-1.6mm collet.

If you already have this gas lens then purchasing this is not a necessity but it is recommended you have an American made gas lens. I have found over the years that imports give less then desirable results
