degassing/infusion catch can

I know this has been covered before, but are you guys buying your vacuum can or making it? http://www.bestvaluevacs.com/ is fairly close by- 1 day shipping, but I’m a little leery about them. I figured for vacuum infusion, you’d want the input side from your sealed mold going into the can by itself- not in a T. The T looks like it could allow resin past the can and into your pump. True?

Went to the local building supply store and found 4" PVC that is rated at over 3 bar, or 100psi. I thought about getting a cap for one end, but I’m not sure how to seal the other. I see people using thick acrylic and a neoprene seal, but I’m not sure where to get that stuff.

Also see a few people using pressure cookers. Good idea? Or paint pots? How about a pickle jar? Any thoughts? I’d like to spend less than $100 ideally, so the big fancy options aren’t on my radar screen. Thanks!

I just looked at Best Vacs website. I think it’s a pretty good deal they offer on their equipment. You can make a cheap one out of pvc. I like a degassing chamber that I can see in. Also the brass plugs can be drilled out when full of resin. With DDC vac hose you don’t have much resin through the vac lines.

I went ahead and got the one I linked. I was going to make one, but for $75, I just got one already made. I guess I’m getting lazy in my old age. lol
