Vacuum Catch Pot used in the resin infusion process of composite materials.
I place a disposable fast food container inside the catch pot to hold some resin if it does get to the pot, this is easy to remove and dispose off. I use inline fuel filters on the top of the pot to catch any stray fibers from getting to my vacuum pump. The inlet to the pot I use a common garden irrigation adapter from 13mm to 19mm. I have o rings on the pot cap to fit the inside of the 19mm fitting.
I use 13mm irrigation hose from my part to the vacuum pot. The lid and the base have grooves for where the middile fits and I use 150mm ID o ring to seal.
