Capping buried radiator pipes

[JWO]

Hi, I have removed am old radiator and need to permanently cap the pipes. It's on the ground floor and the pipes are buried in concrete. I have dug out to find a straight bit pipe, intending to fit a stop end cap, but came across an old compression elbow, so wondered if I could simply use a blanking disk. Would a blanking disc be a reliable, permanent solution, considering that it is going to be re-buried, hopefully forever? Or would a stop end cap be better?

many thank

Take the compression out and put a soldered cap end if you can

Hi Jwo
The blanking disc's can be a little problematic so why not expose a bit more & remove elbow leaving the nut & olive on the pipe then fit a stop end with a bit of tape or paste around the olive.
Cover the copper & brass over with some PVC tape or similar so the cement does not touch it, should last a life time.

Thanks for the quick responses. Can't really solder as can't easily empty the pipes, so will do as Chris suggests. Cheers.
