Coupler part # at McMaster-Carr

[Lance Van Nostrand]

Ron,
If I were running the hotter 4 strokes I would definitely use PTFE.  But on 2 strokers I don't prefer it.

A Webra is not a 4 stroke and I like the softer give of silicone.  I use the clear 5/8" high purity tubing because it's good to 500 degrees, which is 150 more than regular silicone.  number 51845k38 is what I order.


  Well, I guess that's why they make Fords and Chevrolets. I prefer the Teflon tubing. I used one piece of 1/2" ID PTFE tubing on the YS 1.40L-powered Advantage that I flew for 2 1/2 years. I never used any clamps on either end.

      Hello,
       
      I was wondering what type of material people are using for couplers for their two stroke engines. I am going to place an order at McMaster-Carr (unless some else has a better place to get it) for the Teflon coupler material. What part # are you using? This will be for a Webra (Mac's header) and Aeroslave carbon pipe. Both are between 3/4" to 7/8" in diameter.
       
      Thanks,
      Emory Schroeter.
