Tomkins Edelmann 258306 Fitting

Read that another brand had leaked during a brake upgrade and this was the part they replaced it with. A leak is not what anyone wants on any part of a brake system. Better flange sealing surface than the others.

Used this to adapt my 98 C1500 line to a NBS brake master cylinder. Perfect fit, brass construction and no leaks.

I ordered a steel fitting and this is not what I received. I already had a brass fitting but I wanted a steel fitting in case the brass fitting leaked. I received a brass fitting which worked just fine and came in a weatherhead bag with the correct part number. In addition, I am giving it four stars because it was brass and not steel.

Exactly what you need to install gmt800 master cylinder in gmt400

Brass would be a better choice for brake line fittings so as to not strip the threads in the master cylinder. I eventually did get this to work, but its a harder metal than the MC

Worked fine

Works great for the newer style chevy master brake cylinder. Fitting went in perfect and no leaks. Works great.
