Thread: Stainless steel double flares

Tweet

I talked to the guys at Inline Tube (where I bought my hydraulic flaring tool) and they said that when you cut the line with a tubing cutter or a cutoff wheel, you work harden the end of the tube.....anneal it after you cut it. He said that a hacksaw was gentle and might not work harden the tubing.....

Robot,

Hadn't thought of that, thanks for the info.

Jack, it is still difficult to double flare annealed stuff.....I would start with a 5 ft stick, flare it, cut it off, flare it again, cut that off, flare it again.....sometimes I burned the entire piece without getting two good flares......learned new words however.

Sometimes, I got lucky and got two flares on the same tube to take....now, I'm scared to ever disconnect those lines.

Pre-flared tubing from the auto supply is much easier.....and cheaper, and better for your blood pressure.
