Morning All,

I seem to be having a problem with my goodridge fittings in the fact that i am not getting a good seal on some of the connections resulting in very small, but noticable (& smellable) fuel leaks.

does anyone know of any sealing compounds i could use on the threads before connecting them together to make a permanent seal. i bought a haylomer sealent (IT DOES SAY ITS FUEL RESISTANT ON THE TUBE) but its useless and the leaks are still appearing

All the best

Alex

What type of fitting are you trying to seal? NPT, JIC,BSP?
What are they made of steel, stainless,aluminium?

Don't use Hylomar or Hermatite or similar on fuel fittings, instead use a tiny amount of Loctite 243 "Lock N Seal" apply and allow it to start to cure for a few minutes before assembly. This product is especially good for banjo fittings on DCOE carbs and the float chamber banjo on very old SU carbs.

If you have copper washers on fittings you can anneal by heating them to a bit over 200c then allow to cool or coll by quenching.

can i just use any thread lock?

Yes but the Lock N Seal grades have some filler material in the mix,

very strange.

banjo fitting seal by sng copper washer, which is softish metal that sequeezes down when fttings are tightened.

other type use a hollow cones whcih again will deform to seal when tightened.

there should not be need to use any sealant.

bet that hasn't helped - are you mixing fittings from different manufacturer's parhaps?

If you're talking about the -6 type AN/JIC fittings, where there is a male-female cone join, then they should self seal. Obviously.

Check the male cones for burrs, and the males and females for scratches on the cones.

Under no circumstance should any type of sealant be used on these joints, anywhere!!!

Sometimes, people get the hose joint onto the fitting not quite right, and these can cause a leak that appears to come from the metal joint.

Just don't put sealant in there, it won't fix the problem! And it could end up very dangerous.

If it's banjos, use fibre washers instead of copper. Buy lots that fit, and replace every time the joints are undone.

I've used hundreds of these, and problems are only caused by what I put above.

Cheers,
Nev.

They are JIC-8 fittings

Why Not?

I plan to take all apart tomorrow so i will double check

How & Why?

I have used Locktite 'Lock & Seal' to good effect - just use a tiny amount though

As Neville said - surely surely surely no fuel fittings should rely on thread sealant??!! If the proper seals, be them cones, o-rings or metallic/fibre washers, are not sealing, replace the fittings.

if they aren't sealing the either the cones are dirty/damaged or you need to do them up tighter.

if all else fails loctite 542 on the thread will seal. It's properly fuel proof too which I don't think the generic lock n seal is.

When the poster does not understand what he is using, asks for help and clarification, and it is given with a good degree of experience and knowledge, then I think I have a certain amount of right to mock/make light of the many bodges offerred.

The parts in question are not meant to have any type of sealant whatsover anywhere near them. To suggest sealant shows a complete lack of knowledge and understanding of how the parts operate.

If the parts are faulty, they need sending back to the manufacturer. This may be a 'batch' problem, and the mfr would certainly want to know about it. I work with Goodrige fittings and know some of the staff, and can say quite confidently, that they would want to know of problems.

They are also helpful on the phone directly.

This problem should have been put to Goodridge first, and not on here, for the reasons put above.

I fully realise that this forum is mostly amateur car enthusiasts, and for someone who has worked with the type of parts in question for over 30 years, those bodges suggested need to be discounted in every way possible.

Quite simply, fix the problem, not the symptom.

Cheers,
Nev.

I just noticed from the original post, these are not Goodridge fittings, but Speedflow. Cheese and chalk. The problem should be referred back to Speedflow.

Goodridge WILL have the logo stamped on them.
