Swan neck for HTP America® 15 Series MIG welding guns. Standard rigid necks and flexible swan necks available. The thread on this is M10 x 1.0 this works with the HTP 15 series replacement guns.
The rigid and flex necks do come with a diffuser as pictured. The diffuser on the flex neck is not removable.
Very easy to install, very self explanatory. Works great like it should to get in those hard to reach areas. Was a little longer than my factory stuff neck as well.
