Hydraulic fittings?

I have not seen this discussed elsewhere. What are your preferences for materials? Steel is strong but is susceptible to corrosion. Brass is weaker and is also susceptible to corrosion? Anodized and zinc plated aluminum are more corrosion resistant than natural aluminum but will corrode if scratched and are weaker than steel etc. Stainless is awesome but very pricey! So what compromises are acceptable. And why am I so concerned about corrosion? A horse trainer friend just had her brake line to the rear wheels blow out while towing. Not a good feeling. I am installing my new fuel system in the next week or so and have options on the fittings. You have to remember that for 6 months out of the year these will be subjected to a fine daily spray of MgCl2 and NaCl solution. The underside of my truck is disgusting it has so much surface rust. So what are your choices and why? (And those of you who's truck is subjected to this environment should get under their trucks and inspect those brakelines!)

Re: Hydraulic fittings?

In your environment stainless is definitely worth the cost IMO

Yeah, I definitely need to find some stainless hardlines for the brakes. But the fuel system is not under that kind of pressure.

Re: Hydraulic fittings?

Is it even possible to find SS AN hose connections?

I have seen brass, plated steel, and anodized aluminum but SS???

Possibly they are made for steel braided hose connections.

I have not seen any socketless type fittings in s.s. but you can get s.s. AN/ORB adapters, AN/metric adapters and AN/NPT adapters. Check out SSP fittings.

Swagelock, possibly Parker. Parker is cheaper, Swagelock is worth the price difference.

Re: Hydraulic fittings?

I don't use any aluminum fittings except on the drag car where every Oz counts. Steel (which will be plated) is the best way to go. Brass will fatigue crack from the vibration. All of the stuff that I work on like Class 6+ trucks, off-road equipment,etc. all use steel. In the case of corrosive fluids then stainless is the way to go, but cost is very high.

Steel JIC fittings are easily available and priced right. You can always coat them with a bit of anti-seize if you are worried about exterior corrosion.
