Teflon tape

I have to ask you guys, in what direction do you wind on the tape. clock wise or counter

The yellow tape has more tensile strength, doesn't shread as easily as the white and it seals smaller imperfections in pipe threads than the white. I could use white tape on a joint and have it not leak at 300psi with water, but the same joint might leak with only 50psi of air/gas.

Looked it up.

White- single density, should only be used on NPT threads up to 3/8 inch in diameter.
•Yellow – double density, often labeled as “gas tape”
•Red of Pink – triple density, required on all joints 1/2? or larger.
•Green – oil Free PTFE tape, required for use on all lines carrying oxygen (i.e. – medical oxygen or welding oxygen lines).

The yellow tape is thicker.
