im trying to fabricate a new hydaulic line for the sls on my 90 300te.this would be the larger return line from the shock to the accumulater.i was able to salvage the banjo fitting from the old line.but in wondering how best to attach to new 3/8 steel tubing.any suggestions out there?please and thanks in advance

I've attached banjo fittings to steel pipes with silver solder. It's a tricky job, since you either have to keep all traces of the silver off the faces, or you have to clean it off after.

how about brazing.ive never used it but i do have torches.

Brazing and silver soldering are pretty much the same thing, but with different materials. I used silver because it was around, and it flows well. Silver solder melts at a lower temperature than most non-silver brazing rods. You can get silver solder and flux at any place that sells to air-conditioning and heating shops.

thanks for the info.ill look into the silver solder option.i would assume i can use my aceteylene torch for this.its been too many years since i last tried silver soldering.at that time i was just a lad working in me grandpappys electric motor repair shop. we used silver solder to attach new contacts to the heavy duty switches inside industrial duty a/c motors.my recollection was that it produced a much stronger heat resistant weld

I've used silver primarily on bicycle frames. Heat resistance is not an issue there, but strength and fatigue sure are.

Yes, your O/A torch is the appropriate device, although it is often possible to do the job with air/MAPP or even air/propane if the parts are small.
