Bob,

I have found with my gas OS 160 conversion that standard teflon tubing type connections burn through quickly. I have have had much better luck with machined teflon couplers which are holding up very well. Other alternatives are: 1.rolling your own coupler with beer can aluminum and RTV silicone ( I made one but haven't used it yet, cause the machined teflon is holding up so well). 2. Using teflon/fiberglass/silicon imbedded tape to roll your own or reinforce an existing coupler as metnioned from McMCarr. ( I got some of this but haven't needed it yet either).

George.
