Water leaking from black thread any ideas?

[Paddyo1966]

Hi, new to pressure washing bought a pressure washer second hand and put a new hose on it. Attached the same parts from the old hose. But when using it now I get a leak from the black twist on thread. This drops the pressure to the gun and you have to wiggle the hose to get it to stop. Do I need to strip it down again or replace all the parts with new ones. Thank for any advice

Hi, did you use any PTFE plumer tape on the thread when putting it back together.Try this first you can get it at any diy place. Hope this helps.

Try PTFE tape or thicker gas tape on the threads. You may find the leak is actually from a missing o ring in that QC fitting. Worth checking.

Yeah I did about eight turns

It looks like there is something missing. i.e. the brass connector seems to be in too far on the black plastic bit so the bottom of the brass is not seating in the plastic.
Are you sure there wasn't a washer or o ring on the old one?

Not that I noticed, could the brass fittings be the wrong type for the black fitting?

That looks like strange....looks like a QR type fitting with a M22 twisty black bit on?
