The Threeworlds 22mm Fusion Removable End Cap is an aluminum insert designed to reinforce the ends of compatible dragon staff tubing when using clamp-style dragon staff hubs. It fits inside 7/8 inch OD x 3/4 inch ID (22 mm OD x 19 mm ID) tubing, adding structural support where the hub clamps around the outside of the staff.
This reinforcement is particularly useful with carbon fiber staff cores, where concentrated clamping pressure near an unsupported tube end can increase the risk of cracking or damage. The end cap supports the tubing from the inside while still allowing compatible clamp-style hubs to be installed around the outside.
Designed for Clamp-Style Dragon Staff Hubs
These removable end caps are designed for dragon staff hubs that clamp around the outside of 7/8 inch OD (22 mm OD) staff tubing. Compatible setups include:
- Threeworlds Fusion V3 Dragon Hub
- Bonobo Flow Dragon Hub
- Gora clamp-style dragon staff hubs
- Flowbonacci Plug Hubs
The insert reinforces the section of tubing underneath the hub, helping the staff core better withstand the pressure created when the hub is tightened.
Extra Protection for Carbon Fiber Staffs
Internal reinforcement is especially useful with carbon fiber tubing because clamp pressure near the end of an unsupported tube can contribute to cracking or other damage. Adding an aluminum insert provides additional support from inside the staff where the hub applies pressure.
For stronger aluminum staff cores, such as 7075 aluminum, this reinforcement is generally less critical because the tubing itself is more resistant to clamping pressure. The end caps can still be used for additional reinforcement and peace of mind.
If you’re comparing staff core materials, our Aluminum vs. Carbon Fiber in Flow Props guide covers some of the practical differences between the two.
Not for Pressure-Fit Ultra or F3 Hubs
These end caps occupy the inside of the staff tubing, so they are not compatible with dragon staff hubs that need to insert a pressure-fit connector into that same space. They should not be used with Fusion Ultra or F3 Hubs.
If you’re using a Fusion Ultra Dragon Hub, the hub’s pressure-fit connector inserts directly into the 3/4 inch ID (19 mm ID) staff tubing and does not use this end cap.
Please note: This listing is for one removable end cap. End caps are sold individually.
