Pex pipe ID-need help

[bluedog225]

I’m at Restore and I’ve come across a big roll of shark bite X three-quarter inch blue pex pipe.

I’ve gone up-and-down several times on the specification stamped on the side, but I can’t find anywhere whether it’s pex A B or C.

The shark bite website isn’t much help either there, but I’m trying to do this on my phone.

Does anybody know what I’m missing?

Is there an ASTM designation on the tubing? Pex A will be ASTM F1960. Crimp pex ASTM F1807 or ASTM F2159

The catalog shows ASTM F1807, but does not specify the cross linking method.
I will note that while PEX A is generally rated for expansion fittings, some forms of PEX B are also. All PEX that I am aware of is rated for cinch/crimp fittings.

 

[bluedog225]

Good to know about the cinch/crimp.

Here is the ASTM.

It’s pretty odd to me that a date stamped 2013 pex roll would not be designated.

I went ahead and purchased it for $10. I’ll make it work with crimp fittings or shark bite fittings. Though I was leaning towards expansion beforehand.

Also, it is stiff as heck. Thinking pex B.

Seems like there's really no way to tell

 

[bluedog225]

I‘ve got an email into shark bite customer service. Shirley there is a way to tell.

 

[bluedog225]

Apparently it’s pex b. This is from customer service.

Dear Ray,

You have an entire page on your website dedicated to Pex A vs. Pex B. This information would be very useful if it were added there.

Thanks,

I have a roll of 3/4" Pex A Sharkbite brand.

ASTM F876/F877

Edit...

Also has ASTM F1807/F1960/F2098/F2159

That mean it's expand and/or crimp?

I bought it for a good deal off Amazon previous owner plumbed the main system with 1/2" pex B so it has **** for flow.

but found everything Lowes and Home Depot has fir fittings is Pex B.
Not even sure where to get Pex A stuff. I have an M12 expander.

That's correct.

Home Depot near me carries Pex A. They have a section dedicated to Pex A pipe and fittings. I've seen it in four stores near my home and work.

Standard Specification for Cold Expansion Fittings with PEX Reinforcing Rings for Use with Cross-linked Polyethylene (PEX) and Polyethylene of Raised Temperature (PE-RT) Tubing

www.astm.org

Google will look up the other ASTM standards too.

For expansion fittings, supplyhouse.com and Menards were my choices.

My local Lowes only carries crimp fittings and tubing. Nothing for expansion.

No Menards and Supply House is very expensive for shipping. To the point I've shipped stuff to Maine and had my folks ship to me for much, much less than they wanted for shipping.

I didn't expect Pex A to be "rare" as B is kind of **** for flow in comparison.
May just sell the expander and go with B.

 

[Sumboodie]

That's correct.

Home Depot near me carries Pex A. They have a section dedicated to Pex A pipe and fittings. I've seen it in four stores near my home and work.

I'll have to check.

Was either there or Lowes I was at, shopping for something else and ended up in the Pex section.

...I didn't expect Pex A to be "rare" as B is kind of **** for flow in comparison...

Huh? The difference in flow of A vs B is hardly anything. If that small of a difference mattered in the real world, people here would be saying copper M is better than L.

Psst....

Look at the fitting ID

Psst....

Look at the fitting ID

I don't need the whisper. The losses due to the fitting ID are insignificant compared to any reasonable length of run. PEX circuits don't need large numbers of fittings, and in truth, even the thick walled plastic compression fittings are fine for just about every application (they even have some corrosion advantages in some cases).

If your system is so marginal that an expansion fitting won't work over a compression fitting, you're using undersized pipe, but expansion fittings won't make the difference.

Bass awkward comment?
