Polyethylene pipe fitting

[bluedog225]

My neighbor is an old marine, retired from Johnson controls as a construction manager. Point is, he’s been in construction for decades and decades on civilian and military jobs.

He swears there is a polyethylene pipe fitting that allows the line to slide in. Like a shark bite. He strongly recommends this instead of a normal barbed tee or a Ford/pack joint.

I can’t find this fitting. It’s possible he’s misunderstanding the water line project. But I don’t think so.

He says these fittings are 100% reliable and don’t restrict the line in the way a barbed tee would.

Does anyone have any idea what this fitting might be called?

Thanks

Are you sure he isn't referring to PEX, which is also a type of polyethylene?

 

[bluedog225]

He’s up in years but still very much present. He was talking about the virtues of black water pipe.

I don’t think he’s ever seen a shark bite.

I was an engineering with a company that did a lot of poly, Teflon, etc. tubing and the like back in the day. Many manufacturers make tubing fittings that secure to the OD of tubing.

Pipe is controlled / specified differently that tubing, could that be what his reference is to?

I vaguely think I saw something like that a few years ago, and yes, for black poly pipe, but I have nothing beyond that little tidbit. Since I have to replace my supply line, I'd like to find those. Failing that, I noticed that HD now carries some blue plastic fittings that appear to sort of screw in. I'll probably look into those and see what reviews say.

The Lasco Blue Twister are for irrigation line. I would be wary of using them on street pressure.

 

[bluedog225]

He was definitely describing some sort of push to connect fitting. He said he had all types of fittings-straight, angled, threaded end, etc.

It may well have been some industry thing that we don’t have access to. Or maybe not polyethylene pipe. Though it sure sounded like it.

John Guest has a ton of stuff that is popular that sounds like that (especially in Europe).

Ah. I hadn't looked at them beyond noticing that HD showed them on the poly pipe page. We have a well with about 45 psi, so they *might* be OK, but I won't take the chance. Thanks for letting me know.

I can find them rated for Gas line, geo-thermal and conduit but not many for potable water. I have found a few that look like they are for water lines but the smallest pipe they showed was 4 inch.

I much prefer brass or stainless insert fittings. For their short length, there won’t be much friction loss. I have repaired many plastic fittings underground that have broken or cracked.

Parker push to connect fittings and Legris fittings are specifically designed for polyethylene tubing. They have a SS grab ring and an o-ring for sealing. You depress the sleeve on the tub end to release the tubing. Millions and millions have been sold.

Also, tubing is measured on the o.d. and pipe on the i.d. I am not aware of any polyethylene pipe but there may be some.

[bluedog225]

Some interesting finds. But not seeing anything for 1.25”. Lots of options for smaller.

 

[Rockable]

I'm sorry but I don't know your application. If you're looking for 1 1/4", I am not aware of any polyethylene fittings that size. What is your application? It it's water, I think you should be looking at Pex.

 

[bluedog225]

It’s 1000’ polyethylene (HDPE) 250 psi water service line. I heard a rumor of push fittings but not finding anything.

 

[Rockable]

Don't think you will find any at that size. Sorry.

I used to sell plastic pipe, tubing and fittings, are you sure he was talking about pressure or maybe he was thinking a DWV application?

JACO is the industry standard but it doesn't go that large for a pressure fitting. I don't remember ever seeing a pressure fitting for your size.

https://www.jacomfg.com/fittings/

Parker Hannifin is also an option but they also don't go that large

https://ph.parker.com/us/en/series/plastic-push-to-connect-fittings?

Maybe he's thinking about socket welding where a heated paddle with male and female sides is used to melt the fitting and tubing, then it's slid together, melting, creating a nice bond.

Found another but don't know where to buy them. These specify they are NSF rated so should be good with potable water.

Found a place that sells them. They are proud of them. Are you using IPS or CPS size pipe?

Maybe I'm way off base here, but isn't potable poly actually sold by ID?

1 1/4" poly then would be 1 3/8" OD.... all tube size sharkbites should work with it then:

A little google fu shows that I am somewhat correct....

pex press connection or SharkBite connection on black pex type hoses

Personally unless the run is substantially long, I would use a coil of pex A. Much easier to get fittings for.

 

[bluedog225]

I stopped getting notifications there were new posts in this thread.

I believe HDPE is sold and CPS and IPS sizes.

Turns the brother of the guy doing the trench works for the water company. I was able to get some municipal 250 psi pipe. And they specified these couplings, which seem to be exactly what I was looking for. Thanks all.
