Hi
I ge that when i am using speed fit 15mm i need to use the STS when going up plastic to plastic.
I need to join this to a couple of radiators which have a compression olive fitting on the trv end and the shield end, should i be using the plain one (TSM) so i can use the olive on the fitting?
Or are the STS ones able to be used in both instances? ie don't use the olive
Confused
