I'm replacing the boiler in my old stove, when I removed the pipe unions there was the remnants of some PTFE tape around the pipe shoulder... Is this common practice? I thought it would be around the male thread on the boiler? Though unlike an olive with a tapered shoulder, this junction is flat/ butted.
Some pics to give a gist of what I'm trying to achieve as I wait on the new boiler... I've stuck a cork in the pipe to stop the drip, drip, drip. ... Any excuse to crack open a bottle vino collapso
