Prv leaking

[XanderHarris]

I have this pressure reducing valve leaking from where the black plastic bit screws in to the brass housing. Is a new prv the best fix here? Thanks

Yes.

PTFE will be cheaper

Implying taking the head of and PTFE ing the o-ring?

Lube the O ring and apply PTFE to the threads

 

[XanderHarris]

They screw out easy enough?

 

[XanderHarris]

It won't effect the pressure reducing mechanism inside?

Nope

Will there be a spring under the plastic cap?

So I have the new valve I am going to swap it. Can I ask the gauge that screws in to show the pressure has an o-ring in the end. Bit if screw in tight it doesn't have the gauge showing vertical. (As the picture). Would I be better using loctite 55 cord so I can get the gauge vertical so is easier to read. Also with it being the same valve I should be ok just undoing the nuts PTFE-ing the olives and reconnecting the new valve? Thank you.

Ptfe is a thread sealant, not for compression fittings.

Sorry I ment put a couple of wraps in the olives to help seal.
