BT80 Tube Couplers

The Estes BT-80 Tube Couplers are a useful building accessory for educators, group leaders, and students working with larger model rocket designs. By connecting BT-80 body tubes, these couplers help learners explore how rocket length, structure, and alignment affect a finished build.

Hands-On Design Exploration

These couplers give students the flexibility to extend rocket bodies, repair damaged sections, or test custom configurations during classroom and group projects. They are a simple way to turn a standard build into a more creative engineering activity.

Reliable Parts for Learning Environments

Each coupler is made from spiral wound Kraft paper, providing a strong connection without adding unnecessary weight. The easy slide-in design helps students focus on careful measuring, assembly, and problem-solving as they build.

Great for Classrooms, Clubs, and Camps

With two BT-80 couplers included, this pack is a practical addition to any rocketry supply bin. Use them for STEM lessons, youth group builds, summer camp activities, or custom rocket projects where students can apply real engineering concepts through hands-on construction.
