Looking to replace old air vents in home, anything special about these?
I’m just a green HVAC tech but have been looking to improve my system at home. I’m looking to replacing all these air vents but boy they’re old…is there anything special about them I don’t know? They’re just normal manual air valves correct? This is a simple closed loop baseboard system with an expansion tank, I’ve had someone at work tell me I don’t need them at all. I figure it’s always good to ask experts before tinkering with the dead men’s work!

I would wait another month or so before attempting this task. If or when something goes wrong, you'll have time to fix it!
Have a 1/8" tap available.
Small pipe wrenchBox wrenches.

What type of expansion tank do you have? Bladder or plain steel compression?
Do not use automatic air vents with a plain steel compression tank.

You'll never get the WD to travel up into the threads…………………
Hit them all with a torch to expand them………….then you won't break anything.

Those look like they may be old fiber seat auto vents. Try cleaning them up with a small wire brush and/or penetrating lube. You may be able to open them with a wrench or pliers.
