Professionals do not do that. They understand how the fitting works.
I'm a professional - I understand how the fitting works. I don't cut Hep2O with a hacksaw - I understand how that works.
PTFE is a much better lubricant.
A well lubricated joint can end up (for the same torque) being done up tighter than is necessary. Hence in industry - torque settings are specified as either dry threads or lubricated threads.
You are not!!! You are a jack-of-all trades handyman. I wouldn't trust you with a heating system.
Amateur, it is NOT!
Spot on.
For once I'm with Dribble, though for different reasons.
PTFE may have lubricant properties, but PTFE creeps under load. Therefore the initial force in a compression fitting will dissipate over time. I also, have never seen a professional plumber use PTFE on a compression fitting, and only on taper threads where any significant force is radial, and not longitudinal or axial.
Is a light rub with sandpaper the best way to clean old copper pipe when refitting it? [g]
