Sullivan Pro Flex Tubing

[Robert Zambelli]

Saw an ad for this in model aviation.

Anyone use it?
I'm looking for the best universal tubing that I can find, that will work with glow, gasoline or Diesel fuel.

Thanks for any help.

Then proflex is probably it. I used it for the smoke system on my 1/4 scale CAP 10, after using tygon for years. It does what it says on the packet, remains pliable for years, whereas tygon tends to go hard after a while.

I don't know how it goes with glow fuel, because I'll still use silicon tube wherever I can, but for gas, diesel and smoke oil it seems fine.

Thanks for the info, Guys.
I'll get some and see how it performs.
I fly Diesels, glow and spark.
With spark, I always use gasoline, castor and Lucas synthetic.

I like silicon for alky and neoprene for mineral, that inbetween stuff can be mealy and crack. I've never tried the Sullivan stuff though.

Neoprene will decay as well.

Proflex is pricey. But if it works. Then it's a winner.

I have a small stash of it but haven't plumbed anything with it yet.  It does seem more pliable than silicon and I fly the smaller .35-.40 ships which use the shorter 3-4oz plastic clunk tanks.

 I use it alot. All in glow fuel tanks. Its the most flex able fuel line i found to allow the clunk to reach the ends of the tank on small tanks. Its the bees knees.....Gene

FKM is popularly called Viton, which is a Dupont brand name. The chemical compatibility charts show: gasoline “A”, diesel “A”, castor oil “A”, methyl alcohol “C” fair, nitro methane “D” severe effect. Your milage may vary, just keep an I on it. https://www.calpaclab.com/viton-chemical-compatibility-chart/

This is an interesting find, as I know a lot of RC cars use viton seals on their exhaust systems (and my old 140 RX used one on the Hatori Tuned pipe coupler, and they're not scared of using nitro. Perhaps being on the exhaust side of things means that the nitro is used up?
