There was a question today about putting a cap on a tube of caulk that would keep it from spilling everywhere that got me to thinking. I used to work in a print shop that used different-sized plastic caps and plugs from Stock Cap all the time. These caps were great because you never had to worry about breaking one or mistreating it — just grab another one.
Stock Cap has extensive molding capabilities that allow for a wider selection of vinyl, rubber and plastic plugs and plastic caps for general product protection. It’s the largest dip-molding company in the world, so more than likely they’re going to have what you need.
They’re nice people, and they have a great website. The only hitch is that you get a lot of caps/plugs per order — a few thousand for about $40 — so you’d better make sure you need a few, or else split the order with a buddy or two (or ten).
If you’re a pro and you burn through a lot of plugs or caps, this is defiantly the way to go as they’re going to have what you need.
