Brass Fittings used in hydraulics?

GWMiller · Apr 28, 2011

I have a 460 that I am putting a loader on. The hydraulic couplers in front (that the culitvator use to plug into) are shot.... like rusted solid and all the ball bearing are gone shot. I figured I could just put new couplers on but I then realized that it was 5/8 threading. So I went to my hydraulic hose guy buy he couldn"t find any reducers in stock. I did however find the right reducer from 5/8 down to 1/2 in brass at the local hardware store. It has a much thicker wall than those damn steel lines that run under the seat to run the fast hitch. Will those brass fittings handle the pressure?

Thanks

Not recomended, but we have some.

Brass can work harden and crack. I would replace them as soon as I ordered the correct fittings. Use Hydraulic rated fittings, not plain sch40 pipe! Jim

SERIOUSLY, something doesn't add up here...

NO such thing (at least common stuff you'd find at the hardware store) as 5/8" pipe thread.

It's either 3/4" pipe (which would be EASY to find a steel bushing to adapt to) or an "ORB" fitting that uses an "O" ring (which the hydraulic shop would have had).

Brass adapters made from CA360 Brass with rolled threads and one-piece design are rated up to 2000 PSI.......great for air/water -low pressure apps. They typically are available in SAE 45 degree, JIC 37 degree, Hose Barb, compression, poly-flow, pipe, inverted flare, and poly-push fittings. This means you will be able to find brass that will fit your hydraulic app.....but will it work?
Steel adapters both forged and straight one piece design rate to 10,000 PSI. nuff said.

The fittings from the local hardware store sure as HE** aren't rated for 2000PSI!

I'm with Bob.

The couplers should have the "O-ring" style fitting and thread on them.

THIS is what you need:
