These tubes were manufactured specifically to match NEPT tubes when they went out of business. The ID is sized so you will still be able to use tooling made by Wolter, SLD and others.
With the sudden demise of NEPT, convolute tube users were left scrambling to find a replacement. Much to their surprise, these less expensive spiral tubes that they had been refusing to try for years performed exactly the same.
Nozzled, end burners, core burners, whistle, BP, all worked flawlessly. If you have a membership to Fireworking.com you can read the results for yourself.
"I don't really see any point in going much further, unless somebody wants to see if a rocket made with these tubes will fly after being run over by a truck.... Rockets are again within the grasp of newbie pyros with limited funds."
