Hot Valve Blanking Cap, Best Tool For Tightening.

[farmgate]

Hello,

Just thought to ask my first question.

Which type of tool would be best to use for tightening the brass blanking cap that goes on the hot valve connection?

Reason I am fitting the cap is due to purchasing a new washing machine, and as you know they come as cold fill only, and of course it's wise not to just have the hot valve turned off, but to also have a cap fitted too.

The cap is the normal size apparently but after measuring it looks like I need at least a 29 to 30mm spanner.

I can post a picture of the brass cap if needed.

Any help much appreciated.

what i would use is two sets of adjustables, one on the body of the valve to hold it steady and the other to tighten the end cap. Probably good idea to use a bit of ptfe tape around the thread to make sure of no leaks.

Thanks for your reply.

You mean wrap it round the thread as in the picture below?

Here is the cap in question below.

You should have a rubber washer that goes inside the cap, it seals against the valve.

Yes, I have a washer in the cap I bought today which looks the same as the picture I provided, apart from that the washer isn't showing.

If I just tighten the cap with the washer inside, will that be enough do you think? or should I still need to use the tape?

No just the washer and then I just tighten with my teeth,habit I got from my pipefitting days

Oh I see, just that steveb suggested I use some ptfe tape to secure in case of leaks.

By the way the washer in the cap is like a normal washer, just that I saw a similar cap, and the washer in that one didn't have the hole in the middle.

Also what spanner size would fit that would you reckon?

24 mm combination spanner I think

get good adjustable teeth on it just like puddles

by the way, dont use an ordinary washer with the hole as it will let by.
