Air Comperssor to Piping via Hardline?

[TexasStroker]

Alright, I have run my 60 gal 5HP compressor in its current set up just fine for about 3 months. 

I have about 2' of braided line that ran from the 3/4" valve off the compressor to the 3/4" copper hard line to reduce vibrations.

Sunday night, after about 5 hrs of use that day, the hose blew off the hard line side, obviously it made a mess, blew dust around, and scared the snot out of me when I arose from my dust cloud in the trunk floor to see what it was...

Subsequently I'm really considering just running hard line from the compressor to my main piping.  Does anyone else do this and is the vibration really that bad?  My compressor is pretty loud, but I've never had vibrations troubles.  I have it on the pallet, and on a high density mat that seems to be working great. 

My only other option is to try and find someone that can build a flex line (no clue what that would cost...I guess I'd have to go to a hydraulic outfit or something?).

I really liked my set-up, but am not looking forward to a repeat of Sun night.

Any advice/real world experience would be appreciated!

A local guy just might have solved my problem...Posted a link to a aTSC hydraulic hose that only cost $14 for 36"!!

Nonetheless, does anyone run their home/small shop compressor via hardline?  I hate not knowing answers to something that has sparked my curiosity

You need that flex coupling.  I found one at my local hydraulic hose repair place.  They build high pressure hydraulic hoses for construction equipment.  I went down and wandered through their stuff and found the perfect stainless flex hose.  Of course, you could get one made up out of rubber type material.  If they can make them that withstand 1000 psi hydraulic oil, then they will be able to make one capable of withstanding the pressures in a small air system.

Yeah, I really was considering just doing a rigid mount (had the parts, won't blow off) but that hyd hose should be just the ticket for me...
I blve it hanles 2250psi, just enough for my little comperssor 

Thanks for the input though...I'm pretty sure if a hyd place cut me a good deal the hose would prob come out to about the same price as the unit at TSC...
TSC is about 5-10 miles closer than the next place that could handle it, so they win out by default for me, lol!

Any good high pressure hose will do, just make certain that you install it in such a way that the hose is allowed to "flex". If you just go straight from point "A" to point "B" you have accomplished nothing. There needs to be a good curve, or even a loop in the hose to absorb any shock or vibrations when installed correctly.

I just have my compressor plumbed with high pressure rubber air line in my home garage.   
The lines are split going to both far corners with air dryers.

Got to pick up the hose, should be a nice fit...I had my braided line that blew off with plenty of slack in it, no vibration troubles so I'll do the same with the hydraulic line...

I could get by with 20" but the hose is 36" plenty of room to "flex" or "loop."

Thanks for all the feedback!

If I ever blow this hyd hose off  I'm going to just yank all the  3/4" hard line, choke down to 3/8 rubber and buy really good filters/dryers like your set up Bill!  I wish I'd have just gone out like that initially for the trunk floor and THEN gotten into my hard line system...I'd prob be done with the trunk floor install by now, lol...Nonetheless, the hardl ine is working pretty good for me, got all the right slopes, drains, valves etc...Just need to not have a surprise hose come off right before the hard line

I put a ball valve directly on the compressor tank, followed by a moisture collector and dryer, then a hydraulic hose through the wall into the garage. Always turn the valve off when done for the day.

If anyone cares or is plumbing their system in the near future the hydraulic hose works great!  Just ran the 3/4" NPT M thread x 3/4 NPT F 90deg Swivel and then ran the 36" of 3/4" line from there to the soldered on copper fitting...

No vibrations, looks good, pretty cheap (around $20 total), and most importantly the line should not blow off

Actually, I should have been more specific. I have it plumbed with 1/2" rubber line, NOT 3/8".
