When flaring 37 deg ends on steel tubing one uses steel nuts and sleeves.
When flaring 37 deg ends on copper tubing one uses steel nuts and sleeves.
When flaring 37 deg ends on aluminum tubing can one use steel nuts and sleeves vs the overpriced speedshop aluminum nuts and sleeves?

It sounds like the flare is the same, but I wonder if corrosion from dissimilar metals would be a problem. Also, the softer aluminum may deform too much when tightened by the steel nut (?).

Steel brake lines work real well also and I think they are much
cheeper than alum..

Thanks for the input. I'm thinking fuel here and female vs inverted flare. I bought a 20' stick of hydraulic steel tube from my favorite supply house and in just under a few weeks siting outside(protected too) it has rusted both inside and out. I paid $1.13' and the local speed shop has 25' rolls of 3/8" alum for $28. so costs are close. I have all the POR15 tank products but derusting and coating 3/8" pieces of tubing do not sound fun or practical. Supply house does not sell Aluminum tubing and they can't advise. Aluminum nuts and sleeves thru Russell or Aeroquip are astronomical and for weight reasons I think.
