Summit propotional block leaks.

I have an ongoing leak problem on my Summit adjustable Propotional block.



The two ports at the top of the block is leaking. I have changed to factory flared pipes, but it still leaks. I have tried to torque it more. Still leaks.
The block is aluminum, and now I start to suspect that I might have torqued it too hard, so the flare cone in the fitting hole is pushed down on the top and don't seal properly?

I want to try banjo fittings with 3/8-24 threads, and the surface around the holes are machined. What do you think of that.

If that's not a good idea, what's my alternatives? Buying another block is 116 USD. I haven't bougth this one from Summit, so I can't claim a new one from them. And besides that, the freight cost from Norway would be high.

Shipping costs to Europe have risen recently but I still donīt consider them
unreasonable.
I would order a new part and get it shipped USPS or i-parcel.

To me in Spain;

SUM-G3910 $115.95
Shipping i-parcel Charge $37.95, Tax & Duty $24.04, Total $61.99.


Total $189.89 which comes out at 1,139.90 NOK, which is 151.336 EUR.

Do you have high import taxes in Norway ?

Import tax is 25 percent....

But are there any reason that banjo fittings won't work?

Earlier I had a leaking problem past the adapter fittings on the GM Master cylinder, too. On this forum someone adviced me to use banjo fittings. I did, and the leak stopped.

You are using a double flare, right?

I see no reason a banjo fitting couldn't work- providing the threads are matched and the block's threads are undamaged.

Another option is to drill and tap the block to accept a male NPT fitting having a female inverted flare on the end. That gives you fresh threads in the block and a new seat for the double flared tubing. These fittings are available in 90 degrees, too.

An inverted flare joint needs no sealer or teflon tape. The pipe threads do need sealer/lubricant at assembly.

The threads are undamaged. I use a 45 degree double flare and no sealer or teflon tape.

I have found that Harley Davidson bikes are using a 3/8"-24 banjo bolt with downsized head on their front brakes. I have already ordered a couple of those.
I think they will fit perfect, and the price makes it worth a try.
