Subject: RE:Tubing bender and flaring/barb tools... Which ones to get? by Slalom4me on 2008/1/29 2:26:07 Quote: Ya think? That is a lot of hardware to get a "single-rib 'barb'" The reasons to prefer a hose barb over a single or double flare are two-fold. Firstly. The direction of the lip is reversed - a barb is directed such that it makes installation easy and removal difficult, the shape of a flare has the opposite result when used with hose. Secondly. On a flare, the intended sealing surface is the end of the tube where it becomes captured between the two opposing fittings. It doesn't matter that the outer surface upstream from the end is marred & deformed by longitudinal marks left by the anvil portion of the tool used to grip the tube while the die portion forms the flare. However, hose seals along this portion of the outside of tube - imperfections become points for seepage. But enough. CentralCoaster has his solution. If we are going to differ, let it be over something more substantial than this. Incidently, the little single and double 'ear' crimp-style hose clamps seen on euro and asian cars are known as Oetiker Clamps. With proper care, they can be reused multiple times.  . |
