Pnumatics companies

I have a project comming up, and I am looking for some "specialty" pnumatics (2 way valves and such). What companies are out there and who do you think is the best, based on product and price? Keep in mind I am looking for smaller, cocker style (1/8 npt major air fitting, rather small fittings) pnumatics. Also, anyone have a source for stainless hardline 1/4" and smaller?

I get alot of parts from Clippard. Mostly because there is a local distributor nearby. You can order online, but there is an "online penalty". Check the website if you have a local distributor.

Pneumadyne is also great. As is Bimba.

Clippard is the best. We have been ordering from them for years and nothing has gone bad with the products.

Everything else can be gotten from McMaster or MSC.

I'm sure you can find it cheaper if you try, but Palmer's carries ss hardline and fittings.

I know lots of airsmiths use "high end brake line" tubing for hardlines. Fairly cheap.

Now, BEFORE THE ADMIN WHO WILL REMAIN NAMELESS comes on to tell us that using brakeline for hardlines is unsafe......

Its probobly unsafe. Thats often true when paintball uses alot of "off the shelf" parts, its sometimes hard to tell what is really safe, and what is not (like most macroline). I suppose if the brakeline is rated well enough, I don't see a problem, though I'm told that hydraulic pressure is rated 3-times higher then pneumatic, so if the brakeline is rated for 6,000psi, then that means its only 2,000 working max for co2? Something like that.

The harder part is the fittings. The style found are autoparts stores are not sutable at all. But, as I said, Airsmiths seem to use that stuff, so maybe they know something we dont.

I thought it was the other way around. Something rater for 6000psi hydrolic would be 18,000 pnumatic. Maybe Im nuts. Time to do some research...

I'm pretty sure HP is correct. The last time I was curious about this I found a page (wich I can't find right now, of course) which said something about the reason being the compressible nature of gas vs the uncompressable nature of liquid. Once a liquid vessel has burst the pressure drops much more rapidly than gas. Something like that...

Meanwhile I'm trying to dig up some sort of source for this hearsay.
