Blank cap for a Caleffi TRV?

[GaryMo]

I'm looking to remove a radiator for decoration and also to refix a poorly fitted bracket behind it. There's a Caleffi TRV fitted so I'll need a cap to shut the valve fully when the head has been removed so I don't need to empty the system.
Any idea where I can purchase one from? I had hoped there would be something on eBay but no, nothing that I could find.

Are you sure you need a cap? - Some heads have a 0 setting below the frost protection setting for off or maybe just 0C. Alternatively contact Caleffi.

I did notice another cap on Ebay and some fit other makes.

Thanks for your reply.

This valve does indeed have a 0 setting but assumed that a cap was needed for a true off (quick internet search).
A quick email to califfi won't go amiss I guess as I wouldn't want to be half way through removal then find out I have to put the rad back on due to 0 setting allowing a trickle through!

Simple! Negates the need for a cap and probably cheaper.
Thanks very much.

I recently put one in my toolbox for temporary cap off's . The one I got needed a 1/2" tap washer in the end for sealing or I would have to use PTFE Tape on the treads. If you get one check it first.

I use the discs below to keep ends closed off until I am ready to connect to an isolation valve for instance, just in case some one opens it the valve. But you would need a spare nut to use them. You just pop them into a compression fitting instead of a pipe and olive

I use EPDM washers sold for replacement in flexi hoses. They're exactly the right size and have to only be just over hand tight.
