Question
TYGON TUBING REPLACEMENT?

Has anyone found a better fuel tubing for our gassers? I'm not impressed with tygon. It get's brittle in cold weather and is hard to pinch off with fingers when fueling. I'm looking for something a little softer and easier to work with if that's possible.

It gets softer with exposure to gasoline, as long as you leave the gas in it. Aerotrend blue tubing is higher quality. Using a three line system, you never need to pinch off a tube.

Aerotrend stuff is/was the best! I haven't been able to find it for years. Do you have a hook up?

Since I can't seem to get the Aerotrend anymore, I've recently tried the blue stuff from Plane Addicts. It is MUCH more dense than Aerotrend (or Tygon) so forget about pinching it and it doesn't flex as well...but it seems to be holding up better than Tygon. Its been in the tank for a few months now with no discoloration, stiffening, etc. Beware that the O.D. is larger than others, so it might not slip through some fuel dots.

I have not tried Viton fuel line (yet) but I hear good things about it.

Man, I wish I could get a hold of a few 30 ft rolls of Aerotrend line.

Works great on smoke systems too. Muffler temp will not bother it either.

Go to small parts.com they have 10' packages of most sizes. Not sure what the cost but not cheap.

Around 6 bucks a foot at most places that sell it. Thing is, it's costly up front but you wont have to replace it every year or so like Tygon. The cost kinda breaks eaven in the long run.

Just ordered some today from McMasters-Carr. I think it was about $4.50 / foot.

What's the McMaster part number?
I've found that if I don't use a solder on barb with the black tubing, I don't have much luck with it
staying on the brass tubing.

How about you?

60 durometer and yes a barb is required. Viton is a true 1/8" i.d. where as Tygon is a tad smaller. PSP also has all that at a good price too.

I have been using this stuff for the last 3 years when aerotrend disappeared. When I talked to them on the phone he said it was better then tygon. I haven't changed my lines in 3 years. It doesn't get hard or swell up like tygon. But I do use viton for my clunk line
