Wrong. Been using PTFE tape on
Compression Joints (where needed) for 30
years. Boss White is not suitable for
potable water. Must conform to BS
6920, it doesnt. see www.tool-up.co.uk/shop/diy/MISBW.html

He is right. PTFE should not be used on brass compression joints. There
are potable version of jointing paste. This should be used and only a smear
between the body of the fitting and the olive.. Do you put PTFE on the
threads of a compression joint?
