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."
These tubes come in 21" lengths so you can simply cut whatever length you need. If you're tired of keeping an inventory of different lengths, this is the solution.
- 5 Pieces
- .507 ID tolerance +-.005"
- .740" OD 21" long*
- ROCK HARD
- Spiral wound
*Please note the new length gives rocket builders less waste.
