Hi,

I have the 26 (1.60 Petrol) and the header and pipe - I have burned through two couplers in perhaps 25 runs... How long should they last?

Thank you, Dan

Are you really using teflon or are you using silcone??
Teflon is almost bullet proof is why I ask

I've burned through silicone ones, at just about the timeframe you are talking about. Once switched over to true teflon, no problems. Glad someone else noticed too, I hadn't seen or heard of the problem until it happened to me.

the header and the pipe should be aprox 1/16"-1/18" apart and straight in line - see picture - done this way I have never been able to burn out Teflon or Silicone -I use silicone almost exclusively now -just make sure all is aligned and supported

Thanks guys - I burned through the coupler that came with the MVVS26 pipe and header from MVVS so I assumed it was teflon (it was off-white), then I burned through a silicone one (grey color)...

Dick has it right - my pipe is not on a straight line with the header pipe - about 15 or 20 degree angle - so I hope this is the issue - I have some "real" teflon coming from DA, but Dick says Silicone will put up with the heat from the 26 if all is in-line and minimal gaps exist - I will realign and try again.

Thank you
