Silicon Hose Bends

[Alf]

Is it true that 90, 45 degree etc silicon bends are proned to spliting under high boost (1 bar +).

That's the first I've heard of it.

Buy a reputable brand and you shouldn't have any problems. Even the cheaper stuff like Thermal Flex and KKR Silicon tubing I have never had issues with

Only thing I would add is make sure there is no stress in the hose bends. ie dont try and get 45deg out of your 90deg bend etc etc. Also make sure there is no twist in the hose or bends. ie set up all of your pipe work with loose clamps then tighten the clamps when everything is in place.

This is all common sense but common sense is not as common as you would think. make sense.

First ive heard of it too.

I was running 24psi, no problem with Samco (i think thats the brand) bends

Try to avoid a 90deg bend straight off the compressor cover, these are prone to failing which is why the track guys weld a bend on. Mine is silicone and no problems but then again its not a track car!

DCIEVE, how long you been running with yours? I had one put on as well, and probably have 3-4000km on it, but want to change it soon - never can completely trust it after comments made by others. Reckon I'll whip the comp cover off and get a bend welded on. Peace of mind.........

Its mainly due to heat.

I killed two bends in that fashion, but it was my own fault for not spacing it far enough away with metal as you point out

buy and try

I've only done maybe 3-400km's on it so not really a good reference!

Ash, its not the surrounding heat (though it might have been your problem). The ones I was told about were a result of the hot air from the comp cover wearing through the elbow...

[R31Nismoid]

from the comp cover itself?

wow, didnt think that would cause it. Mine was fine on the inside even @ 24psi. It was the outside that had burn scores etc on it.

Mine was just radiant manifold heat melting the hose slowly (over about 5,000kms)
