Water spurts out from there. Try taping but water comes from the inside rather than around the seal. Pipe looks fine, rubber seal insides also looks fines.
What else should I try before just buying a new pipe?
Thanks.
There's an o-ring that prevents water leaking from where you've indicated in the photo. If there's a leak it is either because it has not been tightened properly or the o-ring is missing.
Unscrew both hoses and compare it against each other to see if any part is missing?
