PEX hangers

I want to start laying out my PEX for my air lines.
Is anyone aware of PEX hangers that are more secure that the black ones with the single nail?
 
I haven't done mine yet, but i 3d printed all mine from thingaverse.

I use 1/2" electrical conduit hangers, similar to the copper plated ones above, but much cheaper, a box of 50 is something like 11 bucks (been a couple of years since I last bought some)

I like that subtle detail on the smaller one. Anyone that's ever hung those working off a ladder will appreciate that little snap feature that will keep it on the tube while you fiddle with and drop a couple few screws trying to land one.....:D

I also like the idea of running inside conduit. Maybe not for the whole shop, but for the drops it would certainly add a lot of protection from cuts and glancing blows.
 
Just to be curious, what’s the problem with the one nail mounts? I hung my lines with them 15 - 16 years ago and they’re all still there.

D :cool:
 
I'd thought about the pex and it's ability to collect water in it's many bellies. I balanced out that against it's reduced ability to radiate heat which would prevent condensation, sort of.
I wanted a neat clean system, on grade for drainage to the traps, and concluded that running it inside plastic electric pipe was the best. I had 5 drops planned and wanted to have a riser off the mainline that went up and then U turn to the drop leg to prevent a surge of water. I would have to break the outer pipe run at every drop for the Tee.

I came to my senses and ran 3/4" black iron and put it on a grade of 10 inches per 40 ft. Main line run is 120 ft. I followed the plan below:

For whatever reason I've never had good luck with them. Mind you, I've only used them in plumbing situations where I'm typically at the bending radius limit so lots of stress on them.

Ok that makes sense. Anywhere I had to turn a corner I used a fitting but all my corners were 90 deg.

I’d be careful about bending around edges on things like the U clamps where they might dig in and cause a stress concentration or violate the min bend rad spec.

I replaced the nails with drywall screws in places where I had to go through drywall to get more grip length.

In my experience the one nail clamps made it easier to avoid stress concentrations. The one point of resistance meant that the clamp would naturally find the least stress position.

You do still have to position the clamps so that the PEX tube doesn't kink in between them. Mild (hairdryer) heat can help to 'set' a tube, but anything more is not recommended
 
It's called a 3D printer and with that you can make as many customized hangers as you want. In fact 42 different versions and 42 of each version.
Just don't drive on the left...
