Tail extension leaking

[Andrew74]

Hi, ive got imperial taps that im replacing with metric ones. Ive got two extensions to screw onto the new taps. After taking the old ones out and fitting new there is a leak coming from the extension. The olive is fine. Ive tried ptfe tape and tightened everything up but there is still a leak. Has anyone got any suggestions? Thanks Andrew

I’m not aware of any metric taps, they are still 3/4” and 1/2”.

Better off using a tap connector with fibre washers.

I take it your using extentions because old taps had 2 1/2 in tails?
You need a 1/2 flat washer in extention before you screw it on to tap.

Thanks, yes the tails are 2 1/2. Are fibre washers the same as flat washers? Should i use ptfe tape to?
