Default Plastic Brake lines/fittings

I am soooo tired of leaks in the plastic brake fittings between the firewall and master cyls. Tried a search but no joy so what's the best alternative to these? Is anyone making a kit with better quality components? I saw one post that mentioned SS lines but that was on the gear legs replacing alum.

If they fit the 9 they should fit the six.

You can use standard brass 1/4 inch compression fittings ala ice maker. Much better than the nylon tee that Vans keeps sending along.

I've replaced most of mine with SS braided ones from http://anplumbing.com/.

I'll probably replace the rest after I'm flying.

Call Bret at BONACO. There listed on the sides of the forums pages in company ads. Iam putting in a parking brake and i spoke with Bret and he helped me and i'll be ordering the lines from him. Like one of the guys said Bonaco has a kit for BOUT $180 IN ss for the 9 & 7. Ron in Oregon. Tell Bret I sent you!

You could consider using Nylaflow tube (not Nylo-Seal) with the appropriate brass Poly-Flow fittings ( both available from ACS).
Nylaflow (3/16") was standard for the brake lines from the Master cylinders to the brake calipers on the Vari-Eze and LongEze and generally gave very good service. Over 26 years I never had any leaks in the Nylaflow brake lines or fittings on my VariEze. Rutan's recommended procedure was to install a short length of 1/8" OD brass tube into the end of the Nylaflow where it fits into the brass fitting to give something more solid for the brass sleeve to tighten against.

Default brake lines

Braided teflon is the best solution. A friend installed some on his RV-6, with great results. Kits are great as long as the lengths are correct. The great thing about you building YOUR plane, is that your accessories and bulkhead fittings might not be exactly where the next builder put his. Test fit them first. Properly secure them, and they will last the lifetime of the plane.
