PEX tubing looks like the perfect tubing to run a hot water loop to a
distant bathroom. I see some very expensive tool to crimp the tubing,
using a crimp collar, to the barb. Is there any other way to do this?
That is, without buying $100+ is special tools. Will clamps work? Are
there any compression fitting that can be used on PEX. Thanks.
PEX can be joined with the PEX barbed fittings AND metal rings SS or
copper) & a crimper OR wiith PEX doubler rings & an expander tool.
The expander takes advantage of the shape memory of PEX, the ring &
crimper you're just squeezing the PEX down over the fitting.
I getting ready to do a repipe, I just bought an expander on Ebay. I
haven't got my who repipe system thought out but I guessing that the
cimp & expnader methods use different diameter fittings.
The expander & crimpers can be had on Ebay.
I installed under floor heating with PEX tubing. It's great for loop however
it does have temperature limits. I believe it's somewhere around 160-180
deg. www.Radiantfloor.com has lots of info. Yes you can use compression
fittings. That's how I connected loops to manifold.
I only need 2 fittings, that's it. I will only be running a 30 - 40
foot run from the farthest bath back to the basement where the water
heater lives. I will us a small pump to recirculate. I plan on
controlling the pump with an IR sensor in each upstairs bath. Are these
compression fittings standard PEX things or something you found to fit?
I'm not PEX expert but I've done a lot of reading about it. I getting
close to doing a repipe in my own house. Several guys I know really
like it & have suggested that I give up on my "old school" love of
this site has the crimp tools & fittings
this site has both type of tools
Wirsbo is the leading mfr of this type of tubing, they also make a
screw together type of fitting (appears to have some sort of internal
If you're only doing a few connections that's probably the way to go.
The simplest solution is to get your plumbing runs
cut and already to put together and then rent a
tool for half a day. HD and any plumbing shop
have the crimp rings, something like $6.00 a box
of 15. The tool will rent for about $15.00. Ask
me how I know? Well, my kid asked me to help seal
up the bottom of a trailer after a leak and the
first thing I did was put a staple into a pex
tubing, so I had to repair it.
