I’m using it to do an n2 push/venturi, solvent recovery on the gas side; injecting to the CLS from the liquid side.
Somewhere from the mini ball valves to the tank I’m getting a leak cuz it won’t hold vacuum. I tried linking the tank to the manifold from all 3 ports. I switched out hoses.
The tank itself is as tight as can be. I’ve lost my temper multiple times this week and today with this Situation. The only thing left I can think of is the tank’s MJIC is leaking somehow?
Edit: I’ve also retaped, tightened, tore this manifold apart multiple times.
Ive seen them leak from the valve as well. The valve can hold a seal when closed but it will leak once opened. If you remove the blue plastic you would see this on the brass fitting by using a tool to turn it
The black handle one. If you can looking inside and see if you can see the gasket. These are known to have gasket issues too but it’s pretty easy seeing when you have a defect on one of those
Oh shit I just saw you guys are talking about the little blue ball valve from bvv. Those leak for sure if you press it with a screwdriver you can hear the hiss. I was talking about the valve on the solvent tank. Those go bad too
I’ve learned a lot on this website, like a lot a lot, but I think I’m learning right now to just pay up for the good shit. All this cheap “should do” shit always bites me in the ass. Bvv specifically.
I agree that you should replace that blue valve on the manifold regardless. You might try tightening the packing nut on that purple handle bvv valve as well. I’ve used some of the purple handle valves in the past and there’s been several times where I wouldn’t reach a full vac until I tightened the packing nut.
I’ll definitely be looking into the superlock. I was under the impression nai lock IS swagelock, but I’ll definitely be looking into getting the best valves for my entire system. I’ve taken valves for granted all these years. No longer.
