AIR FITTINGS

uhm, barbed fittings? are those DOT rated?

while they arent dot approved, try somewhere in the neighborhood of 250psi x 4 possible pressures before bursting.... with use of a hoseclamp also.

i have the hydraulic line on mine i dont have 2 worry about anything because that shit is rated at 3,600psi and dosent leak a drop,my opion that is the only way 2 go but it is expensive

Dry (air) rating is less than the liquid weight psi rating. I have heard a lot of good things about using the stuff though. I think last time I looked it up it was around 3000 liquid is about 600 psi dry, something like that. I build couplings for hydraulic line, I know it has been mentioned before but I really dont remember what the full ratio was.

If we could all afford it we would be running hardline with flared fittings. But it is time consuming and expensive. I personaly use DOT plastic and PTC connectors on mine. we will see how they work when I get done. Everyone I know uses them and gives a thumbs up on that. I have had a vehicle on the standard two wall rubber line and barbs held on with hose clamps. I found that the rubber line flexes too much for me. Any who....

the problem is you're using clamps. you don't need to use the warm drive clamp on them.

on my current project I'm doing everything in hard stainless and steel braded now that the shop i work at I can do all my own compression fittings. Makes it a lot easier.

You ask if the Rubber line is Dot Approved? the 216 they use a lot for air brakes for air planes, and some industrial stuff that is, dot approved.

Parkers website says it's DOT approved as well.

As far as dry PSI and Wet PSI being different????? That's probably the dumbest thing i've ever heard.

The only difference you'll find between things rated for liquid carry and dry carry is that liquid carry will have a better resistanst to shock-pressure... where as you won't find that related to dry pressures.

you can also get them at streetbeatcustoms.com. they have all the fittings that you would need or try mic-masterimagecustoms.com
