You may get Deja-vu from this video, as it's the full length (and horizontal) version of an earlier short.
Because China has a huge infrastructure, there are some very cool tools available cheaply from online sites like eBay. This is one of them.
It's a schrader valve core changer, but is designed to change the cores under pressure/vacuum in active refrigeration and air conditioning systems. Note that this tool is not intended for changing schrader inserts on car tyres/tires. I'm not sure what size of port they use. This tool accommodates 1/4" and 5/16" valves.
The extra side port is for extra functionality, including pulling vacuum or injecting refrigerant with the core removed for speed.

this valve has a valve core in it 🤔
Very cool indeed!
We have things like that over here in Germany to change heating radiator valves under pressure. So you dont need to drain the heating system. It is called "Schleuse"… sluice…
Same thing, but a bit bigger.
There is something similar for a SCUBA regulator. It is an inline adjuster for the 2nd stage orifice. You thread the tool between the 2nd stage and hose and you can adjust the orifice under pressure. You can't remove or replace the orifice though.
Also very cool how you say “cool tool”! Yeah. Oh, and I’m sold!
There is Nylog red and blue for that.
Might not be useful for car tyres but maybe bike tyres? I wonder.
Cool tool indeed
My name is HVAC Schrader!
that is cool…. now you need a cool use for it.
I have a few of these in the box, one fit's R-12, one R134a and one now for R1234YF They are different than this one because of the design of the ports but work in the same way. With the price of R12 and R1234YF you really don't want to lose any if you can avoid it.
Very handy tools but unfortunately I've yet to come across one that doesn't leak a little under a vacuum after the first few uses. Even the expensive big brand name versions are prone to leaks but they're still very useful.
I actually thought the brand was being censored and it's just a sticker on the valve lever 🥴
