Air bleeds

I thought a screwdriver driven air bleed was top notch. Now is tooless pushbutton.
Wow

I thought I lived under a rock 😁

Push bleeders are wonderful, until you knock one off, then you wish you'd kept the flush screwdriver bleeds in. That's pretty dang rare, though.

I should have mentioned flush mount air bleeds.
