Important part
I have WAAAAY too many 5 gal plastic fuel cans, from numerous manufacturers. Naturally, there is no standard thread pattern on the caps, there are at least two different pitches. So, I purchased this collar to adapt my Billet spout ( awesome! ) to the cans that require it. Works like a champ. My only suggestion would be that Ai13 offer both collars as a kit, along with the spout.

Coarse Thread Collar
Ordered and received a billet coarse thread collar for my Rotopax can. Fit and finish was perfect! No complaints, I’ve ordered from Ai13 before, and their products haven’t let me down.
