Rated 4 out of 5Â by P3GS Used on 8mm radiator pipes
Got these so I could drain down my central heating system (combi boiler) and isolate 2 radiators while I remove a stud wall then repressurise the system so the Mrs can have a shower.
They worked well, seem well made. I am a bit of a compression fit stickler so these did the job. Hold over 2bar of water pressure no problem and no leaks.
Only down side is they are a little expensive but they like I said they are not a cheap product. Gave reliability 5 because they don't look like failing.

Been using these for years and never had a single problem with them. Mainly used when fitting gas hobs but I've also used them on microbore central heating systems.
Especially useful when the heating system is taking an age to drain down and a soldered joint isn't an option.
