Pietenpol-List: Leaks

Post by matronics »

Subject: Pietenpol-List: LeaksPieters,If anyone has a solution to seal hydralic fittings from leaking please sound off. I go from alum cyls to brass fittings, to plastic tubing to brass again then to alum caps and alum tubing. I need a good mastic of some kind. The worst leaks are at the cyl to the first fitting. I even tried J B Weld to no avail.Corky in leakie La________________________________________________________________________________

I bought my spar stock from them. They have rough stock only. Greatquality but mostly in 1x6 to 1x10 up to 20' long. They are very good aboutletting you sort thru things.Also, I bought my fittings from Replicraft. I am very happy with thequality.Dick----- Original Message -----

La Leakie;I'm not sure if you're using a combo of standard AN aircraft hardware, brassfittings and auto hardware, but be aware that the flares on aircraft tubingand automotive tubing are different. I can't remember exact numbers, but ANis something like 45 degrees and auto is 37 degrees or something like that.Also, you might try coating the threads with a product called "Fuel Lube".This is a good fuel/oil resistant, thick, lubricant that will seal leakythreads and/or fittings. If all else fails, 'tighten it 'till it smokes andback off a half a turn'.See ya in the Caymans.......Chris HouseSmilin' cause we be buildin' Piet ribs in tomorrow and I ran my Waco todayafter a total rewire....(without a meltdown)----- Original Message -----

Corky,In my experience as an auto mechanic I have never heard of any sealant being successful to stop leaks in an hydrolic brake system. All fittings are a mechanical seal relying on the perfect mateing of the joints to prevent leakage under pressure.You mention using plastic hose. Plastic is sometimes used in hydrolic clutch systems as they operate under a much lower pressure than braking systems. I have not come across plastic tubing being used in brakes before. Make sure all your fittings are compatible with the master and slave cylinders.(thread and cone angles)Cheers,Rod W. still playing with wood in West Aussie.>From: Isablcorky(at)aol.com>Reply-To: pietenpol-list(at)matronics.com>To: pietenpol-list-digest(at)matronics.com>Subject: Pietenpol-List: Leaks>Date: Sat, 2 Jun 2001 18:36:20 EDT>>>Pieters,>If anyone has a solution to seal hydralic fittings from leaking please >sound>off.
