Need Help Identifying Vaccum Valve

[vacpump2019]

Hi all,

I am looking for the receiving end valves of a vacuum pump hose to install on a box that I want to evacuate out of air. The vacuum pump I am using is a Franklin Electric SD-90 Varian, Model 1091045401. I know that such vacuum valves exist, and I attach pictures of what we have that came with some of our equipment when we bought these items. I am looking for the types of valves in the attached photos, but I cannot find anyone who sells just the valves all by themselves. I've tried a number of search terminology "vacuum pump valve hose 'chicago faucet'" and combinations of these words, but I cannot locate anyone who specializes in vacuum pump valves. What is the technical terms for the types of vacuum valves I am searching for? That would help also.

Those really just look like regular gas valves, usually called gas cocks.
You aren't looking to pull a serious vacuum so a simple brass one should be fine.

Perhaps those valves are being used for vacuum, but they are not vacuum valves. Two are stopcocks with spigot-type tube fittings. The push button one is probably a globe-type valve with an and integral push-lock tube fitting (one brand is Legris). Look for laboratory supplies, and tube fittings and valves.

Would the "Chicago Faucet" work for the "vacuum" I am working with? The nice thing about a "Chicago Faucet" is that its nozzle matches the hose I would stick on the valve I get during vacuum.

These are commonly used on lab benches for air, pure gases, and modest vacuum.
You might want to take it apart and relube it with silicone grease.
This will work fine for a rough vacuum.

If you're looking for 'proper' vacuum valves then take a look at Edwards High Vacuum. A lot of years building vacuum plant.
