I’m a 16mm mlcp kinda guy and am tooled up to press this and copper. 
 

Any benefit of using an mlcp radiator tail (pre bent, single joint under the floor) instead of a bent length of 15mm and a straight coupler under the floor?

 

The only benefit I can see is there’s one less press joint. But the 16mm rad tails are close to £10 each, vs £2.50 for an M to U female/female press adapter.

 

The benefit of using a straight adapter is I can make the 15mm hockey stick long enough to do TBOE to bring the TRV up to a more accessible height. Can’t do that with a pre-bent 16mm tail.

I went for adapters in the end, much cheaper…
