Craft Paper Coupler
Perhaps it's because I'm more "old school" that I am more used to the gray rice paper coupler material that Estes and Centuri introduced in the early days of model rocketry. Perhaps those older couplers worked best as staging couplers, whereas this longer craft paper version is better used as a tubing coupler, especially when gluing longer tubes together. (I found it sometimes difficult to get good tubing alignment using those older, shorter couplers.) This item fits my ST-10 tubes well; perhaps I should have ordered more.
