Re: Side can tap

Both those fittings look like they're for R134a hoses.

Is that what I'm seeing, or is it for both R134a and R12?

Re: Puller fans: one or dual

The 2 smaller fans may have more coverage area.

Vacuum pump capabilities vs altitude.

Say you have a single stage vacuum pump that can goto 100 microns at sea level. If you goto 18,000 ft, where the air pressure is roughly half that at sea level; can you get down to 50 microns with the same pump? The exhaust is only working against half the air pressure, so wouldn't the micron level ...

Re: A/C works after car has been sitting a few hours only

You can test the wide gap by giving the clutch face a tap with a hammer handle when the engine is running.

Gland Nut seal grease

Had to tighten up my gland nuts on my gauges yesterday to stop a leak.

HVAC R22 mineral oil

Is the mineral oil for R12 the same as for R22?

I have some 525 viscosity mineral oil for R12, can it be used with R22?

I'm having trouble finding specs on what mineral oil to use for R22



thanks
