One of my favorite tubes. Put the stripper tool in a cordless drill, it's faster and leaves a cleaner end.

In some cases the straight 20 footers work better for mechanic room piping, etc, especially in the larger diameters.

Short cut off make nice wind chimes

@Paul S - new boiler too? The one I just finished, I installed manifolds with flow meters and valves so I could dial in the gpm for each radiator.

@Stephen Minnich boiler is new...installed by another company....im repiping it....contractor installed radiators in a series loop with 1/2 pex....all 3 floors....im installing homeruns from each radiator to manifolds...manifolds are 1in CU by 1/2 pex with valves....no flow meters....each rad doesnt need more than .8 gpm in my calculations....i get good results on resi systems like this....i guess im going to start to use manifolds with flow meters what manifolds do you use?
