Let's say I have to replace a spray body,I twist it out with the Channelocks,see that it was installed with a nipple.I coat the female threads of the new body with some Rectorseal(just the right amount),then spin it back down.No muss,no fuss.
In an open hole,I use tape.It's the "Use No Dope" thing that bothers me.
Should I watch my back?
