PEX For Shop Air Lines?

[Clare Snyder]

Another important consideration is to ANCHOR whatever you are using, particularly if it is flexible. I'll never forget the time the fitting on an air tool broke off and 50 feet of very flexible hose went flying around the shop with a hard heavy air connector on the end. By the time someone figured out what had happened and which hose it was, and got it disconnected, it had inflicted damage to several bodies and a couple of cars.

Attempting to catch it was a futile excercise at best and resulted in a large part of the "bodily injury".

I have to get around to hardlining my home garage so I can keep my airline length to a sensible and safe length. I've got the type K copper and fittings and brackets sitting waiting for me to get my ass in gear and get it done -- -

I believe that those ratings are working pressure, not burst pressure, but I haven't sprung the 50 bucks or so for F877 so I may be mistaken.

[Clare Snyder]

Also with hard line it is common practice to put a "drain leg" at each connector point. The air hose points out from the wall, and a stub leg hangs down, usually with a drain valve on it, while the air pipe runs straight through. The legs catch moisture as it settles into the pipe and tries to find a low point. The low point is then out of the air stream and can be easily drained.

I have a couple hundred feet of 1/2" tubing in the basement. No time though. I'm trying to get some sheetrock up before I gotta go back to work next Wednesday.

Really? DUH! I guess I should have said PEX is used "as","for" or "in place" of water lines_. I should know better when writing to the reading challenged. My obvious point was that water shouldn't bother a product designed as a water transport item.

I also noted to get a water separator/regulator. I should have added if you live under water, like in Texas, you might look into an automatic moisture drain valve.

OH, by "in Texas" I meant on top of the ground, not actually in Texas ground...

[Jack]

Well, that is what you asked:

"Is this something that I really need to be concerned with? If moisture is really an issue in PEX, isn't it an issue in the retractable hose also? In *any* hose in fact?"

If you weren't concerned, then you shouldn't have asked. How am I supposed to know how dumb you are?

So you think the _type_ of line will cause moisture in your tools? That's even dumber than I thought. I'll be more specific for you. Moisture is not an issue in PEX, not an issue in retractable hose, not an issue in any hose. It can be an issue with your tools, irrespective of what _type_ of line you use. Water is dealt with by using water separators and automatic moisture drains.

[Jack]

I agree, mainly because plastic becomes weak and brittle when exposed to UV light. Not a big concern inside a house, in walls with little sun light, but why fool with it. Of course, I recall my kids had plastic swing sets and toys, forget the name, but they were indestructible. Most ever happened to them was some color fading.

[J. Clarke]

You seemed to believe that PEX was some sort of additive. In any case, .

[Jack]

Contextually, that's about as remote a belief one could get from my statement.

In any case, .

Again?

Keep this up an you'll be talking to yourself...

[DerbyDad03]

You've used the words "reading challenged", so I guess I'll have to explain it to you.

If you are going to quote what I said, make sure you quote enough to keep the context.

I said "I've been reading and watching videos about using PEX as air lines in home workshops"

I also said "The only downside that I heard mentioned was moisture collecting in the PEX."

I then addressed that downside by asking "If moisture is really an issue in PEX, isn't it an issue in the retractable hose also? In *any* hose in fact?" It was a point of discussion, essentially a rhetorical question.

Here's the explanation for the reading challenged, such as you:

If a person is going to claim that moisture in PEX is a downside of using it as an air line, then they should also be claiming that the retractable hose, in fact *any* hose, has that same downside.

In simple terms, for simpletons, it ain't about anyone being concerned about the PEX getting wet (wow!) It's about the *downside* of using PEX as an air line as compared to any other type of hose. My point is that there is no difference so why would anyone bring it up as a downside of PEX.

Man, you aren't just an asshole, you're also an idiot. Is that specific enough for you?

Be gone 'cuz I'm done with your stupidity.

Lucky you, he plonked you before you wasted time arguing with him.

[DerbyDad03]

I've gotta ask you to explain that one to me.

This isn't the PC compressor I'm talking about, but the location of the drain is the same, i.e. up the side a few inches.

How would adding a tube from the drain valve to the bottom of tank help?

It's not like there's any suction at the valve to draw the water up the tube. The unit has to be tilted to drain it. Once the unit is tilted to drain, all the water will move to the then lowest point and the tube would actually

*block* the drain.

Am I missing something with your suggested tube placement.

[Clare Snyder]

You ARE missing something. If a line from the inner side of the drain valve reaches to the bottom of the tank, when you open the drain air pressure acting on the water will force it out the drain valve.

Mark the position of the drain valve. Temove it and solder a tube into the valve, bent so it will reach the bottom of the tank at the center of the tank, Feed the line into the hole then tighten the valve to it's original position to put the end of the tube at the bottom of the tank. VOILA!!! a drain that actually WORKS - for a few cents worth of materials and about half an hour's work (if you are slow)

[DerbyDad03]

Ok, thanks.

[Jack]

The truth is I quoted your ENTIRE message. Not my fault if you are reading and writing impaired.

I know what you said, I quoted your entire message.

I believe that is just another one of your rhetorical questions, so I won't be wasting time answering.

I won't be going soon so you'll need to figure out how take on that responsibility yourself.

[DerbyDad03]

And here we have another instance of bending the truth is instead of admitting your error.

Sure, you quoted my entire message, but then you quoted a single paragraph and responded as if those were the only words I wrote. That is the essence of removing all context.

"Quoting out of context (sometimes referred to as contextomy or quote mining) is an informal fallacy and a type of false attribution in which a passage is removed from its surrounding matter in such a way as to distort its intended meaning."

See "quote mining" above.

These are not rhetorical questions:

Don't you find it telling that you are the only one that got the impression that I was concerned about PEX getting wet? (Wow!) What does that say about your level of reading comprehension?

[Jack]

I made no error, bent no truth. I quoted your whole entire message, exactly enough to keep the context.

Yes, that was the part of your message to which I was responding. It's how it is done in usenet.

You are the one that distorted your intended meaning, IE: writing impaired.

See full statement I quoted above.

Your words fool. Let me quote your exact statement:

"I then addressed that downside by asking "If moisture is really an issue in PEX, isn't it an issue in the retractable hose also? In *any* hose in fact?" It was a point of discussion, essentially a _rhetorical question_."

Note where YOU stated it was essentially "a rhetorical" question. That was your first "rhetorical question" by your own statement.

Calling me an asshole and then asking me "is that specific enough for you" was your 2nd rhetorical question. You really are out of touch with your own statements. No wonder you are so confused.

I'll also point out that when you "quoted" yourself, you didn't quote your exact words, but changed them to suit your lame, after the fact points.

Don't know what others think, don't particularly give a damn, and its irrelevant to the facts of the matter.

Guess not! I've heard there is no such thing as a stupid question, but apparently they haven't met you.

Water lines is right - and that is 70psi max. The Plex has to be somewhat stronger than 70 to allow for temp changes. Shops can get very hot if closed. If you open up and start using - you might have hoses being blown.

Mart> >> My son bought me a 50' retractable air hose for Christmas. I plan to >> hang it

[DerbyDad03]

Water lines often have pressures that are higher than 70 psi. *Fixtures* might not like sustained pressure that are higher than 70, but both copper and PEX can handle much, much higher than that.

I have copper and PEX lines in my house that are at street pressure, which is usually around 90-95 psi. They are for the front and back hose bibs. The copper to the front hose bib has been there for 60+ years. I tee'd in the PEX for the back hose bib about 30 years ago.

SWMBO was very happy to have street pressure for both her front and back gardens.

"Somewhat" strong? Look up the specs for PEX. Heck, at 200°F, it's sti ll rated higher than 70 psi.

Not my shop. If my shop ever gets hot enough for PEX not to handle

90 psi air, please call 911 'cuz the place must be on fire.
