The Estes BT-80 Tube Couplers give builders a simple way to take BT-80 rocket projects farther. Use them to connect BT-80 body tubes, extend an airframe, repair a damaged section, or bring a custom rocket design to life with a clean, reliable fit.
Build Longer, More Ambitious Rockets
When your design calls for more length, these couplers make it easy to join body tubes and create a larger rocket profile. They are especially useful for rocketeers who enjoy experimenting with custom builds, payload sections, or modified Estes designs.
Strong Without Extra Bulk
Each coupler is made from spiral wound Kraft paper, giving your BT-80 body tubes a dependable internal connection while helping keep the overall build lightweight. The snug fit helps maintain alignment, so your rocket feels solid from assembly through launch day.
A Smart Addition to Your Parts Box
