A Little Pricey But High Quality And Worth It IMO
By B M 
Northern, Colorado
Purchased 06/24/2019 | 
Review Posted 07/19/2019 
JMF seems to be one of the only manufactures who makes mini split linesets over 65'. I was impressed by the quality of the insulation I also ordered a different brand of lineset and comparably the JMF stuff is noticeably better - it's the same stuff that Mitsubishi is using on the pipe in the back of their indoor units if that's any indication. The rest of my project will likely be JMF lineset since I want this project done properly all the way through.

Love the EZ Pull Insulation This 5/8 Tubing Is Very Difficult to
By Millis P. 
Hendersonville, North Carolina
Purchased 01/29/2019 | 
Review Posted 03/17/2019 
I have used JMF Line Sets in smaller diameters and have been very satisfied. The EZ Pull insulation is the best. This 5/8" tubing, unfortunately, was very difficult to bend -- even with a generous radius -- without kinking. Kinked it on the first try. Cut it off and very carefully tried again. Kinked it again. At this point it was too short to try a third time so I salvaged the insulation and bought a roll of 5/8" USA made Wieland Refrigeration Tubing. The Wieland tubing was noticeably softer and easier to bend. If I ever have to do an installation with a 5/8" JMF line set again, I will cut off a flare, remove the insulation, bend the tubing with a ratchet bender, then put the insulation back on. Note that a spray can of dry lubricant makes putting the insulation back on easier.

With this line set already having the insulation installed, it made it as breeze to install. Insulation is good quality.

Great stuff
By Carl E. 
Hamilton Square, New Jersey
Purchased 11/22/2017 | 
Review Posted 01/06/2018 
The white insulated line sets are much better to work with than the old foam stuff. The black foam starts getting funky in use in only a few years, this stuff holds up, stays good, and doesn't grab when pulling through wall, during installation, good stuff.
