Can we blow off these PEX fittings? Sharkbite vs Viega vs Uponor 4
Merry Christmas Build Show Friends! I was wondering the other day how much pressure a PEX fitting might withstand before it pops off, so I had Jordan make me a test rig! In this video we are testing Sharkbite Push To Connect fittings, Viega fittings, Uponor fittings, and two types of crimped Sharkbite PEX fittings with a rig that goes up to 14,000 psi! The results sure surprised us. Enjoy this special Christmas edition of The Build Show!

I like the concept of this comparison test; but the methodology was all wrong. Since the goal of the test was to test fittings; the following should have been done.

1. The pipe length should have been no more than 6" with all pipes being the same length.

2. Each pipe/fitting sample should have been tested individually as the survivors are weakened from the previous tests.

3. Although the hydraulic power pack is capable of 10, 000 PSI or more, a separate gauge in the 1, 000 PSI rating should have been used as there is no way any of these items would get anywhere close to 1, 000 PSI, let alone 10, 000 PSI. A 1, 000 PSI gauge would probably have the failure points register in the middle 1/3 range of the gauge, which if I recall correctly is the most accurate.

4. Copper, PVC and CPVC should have also been included as the control samples for the PEX to meet or beat.

Gotta test this with 120 degree fluid in the pipes, and a gauge that’s useful.

Could be interesting but completely worthless without a pressure gauge to know at what point these fail.

the one thing you did manage to show is how to not seal threaded fittings :)

There’s a reason the hydraulic industry uses a metric straight threaded o-ring port (ISO 6149). Simple and utterly reliable.

I would like to see this done with an accurate gage and the 4 different alphabet types of copper pipe.

I’d definitely love to see a test where the pressure of failure was recorded.

Water pressure in a house is only 70psi, so why is this relevant?

Refer the “Project Farm” YouTube channel for all your properly controlled testing methods.

Also be great to compare crimped copper joints vs a solder joint.

The first connection was loose. IT BLEW AT THE BOTTOM NOT THE TOP!!!

A pressure test without a pressure gauge. Couple of geniuses here.

i'd be more concerned with the leaking at lower pressures

Let's do this scientifically, but make every thing different from each other...

Also, don't put your hand anywhere near pressurized hydrualic fluid.

I'd love to see a test of brazed and soft soldered copper joints! (I expect the allegedly "stronger" braze joints to give first...)
And fit up your testing rig according to mjncads remarks below. I think it is crucial to get valid results!

Great test concept. You could circle back around for a 2.0 test, I'll not provide methodology advice since its in other comments, only say that wouldn't take much to do it again and there was value in the first round (lessons learned).

A thought would be for the future, put a hydraulic ball valve between your manifold and your test hose or fitting. When it fails simply shut the ball valve off and continue with your test

Hand on the lines? Not bright. Only takes a few psi to penetrate skin and cause major issues

For someone who calls himself a building “scientist” he isn’t very good at science.
