I'm really happy with this pot.
There are loads of videos on YouTube showing how to convert it for resin casting. I pressurise mine to 60 psi and it holds perfectly. Bear on mind you'll always lose a couple of psi as the air cools back down.
To convert this in the same way I have, you'll need...
3/8x1/4 bsp male x male fitting
1/4 bsp Tee (all female)
1/4 female to male ball valve
1/4 male to whatever your compressor or pump uses
1/4 pressure gauge (the pot comes with one but I chose to get a sturdier one)
Ptfe tape
The pot also comes with a pressure release valve
There are two holes in the lid, one is 1/4 and one us 3/8. I screwed the pressure release valve straight into the 1/4.
I assembled the other as in the photo but switched the gauge and inlet around. use 3 wraps of ptfe on each thread.
This is how I put it all together, do lots of research and make sure you're confident :)
