The rubber tip the important part. Just something to fit over the stem of the can after taking the spray tip off. You don't want to force a ton of air in there so you don't need a perfect seal.humm, don;t have that kind.
1) long tip, a foot
2) a 'plastic' cone
3) tire chuck.
I guess those have a 'pin tip' under the rubber. I'll check it out.
Thnx
(wont purchase - just like 'rags', 'hand cleaner', more - I don't buy nuttin)
Just about any rubber-tipped blow gun will work.
