[NSRCA-discussion] fuel tubing

[rcmaster199 at aol.com]

Chances are very good that, with only a handful of raw material suppliers in Industry, the raw rubber stock came from Dow or GE. The color means nothing and the formulation is most likely general purpose which means it has a fairly high durometer (hardness) of around 50 units. GP silicone is resistant to many things we use in the hobby, including Jason's 30% fuel. Ingeneral, 50-60 duro is fairly highly cross linked which makes the stock firmer and stiffer, more chemically resistant.

There are many specialty applications/formulations but I seriously doubt we need any of that for our application except as pipe, header couplers.

I've?had access to?lower durometer thinner walled stock for a medical application I use here at work. Have used a piece of that in the tank of the Oxalis 50 as a pick up tube. Works super since it's extremely flexible. And BTW, you can get various silicone rubber stock, in stock colors of clear, red, black, yellow, blue and green?from distribution such as Mcmaster Carr or Small Parts.

I can't find Aerotrend anywhere so I bought 10 feet of Du-Bro from the LHS  to test it before buying a 50 foot roll.  It works well on the 170DZ and has a higher durometer than Aerotrend.  So far I like it better than Aerotrend and now that Prather is gone.....DB  is about the only game in town.
