1. This tutorial shows how to make a useful adaptor to boost the airflow into a tyre. Out in the cuds, you need to be resourceful and to be able to effect self-rescue. “Never ride alone” is a bikers watchword. If your buddy also has a compressor, you can double the air volume into the tyre by combining two compressors. Read on….

2. The Gemini air delivery system

3. ‘Gemini’ is the term used for ‘twinning ‘ two tools to make one powerful tool. On ships, to lift heavy cargo, the stevedore Gemini's two cranes together in tandem. To be able to Gemini two compressors, you need to have this handy adaptor

4. From your local hardware, purchase a 6mm gas branch – either a “T” or a “Y” branch, and 4 jubilee clamps

5. From you local tyre or motorbike vendor purchase the 90º valve extender and a new tubeless tyre valve. Buy a short length of 6mm rubber pipe which you will need for the second valve

6. Using a bench grinder or a carpet knife, pare off the rubber moulding from the new tubeless tyre valve until it is naked. Take care not to injure yourself or damage the brass valve

7. Cut the 90º valve extender tube at roughly the half length mark. Soak the rubber tube ends in hot water. Lubricate the brass and join all the tubes to the “Y” piece.

8. You will have used the extra length of 6mm rubber tube and the pared naked valve to connect to the “Y” piece.

9. This gadget allows you now to connect a second compressor to the air delivery and boost the volume delivered to the tyre.

10. The additional boost of increased air volume is very useful to get the tyre back onto the bead. It will avoid a lot of frustration, save time, and fits easily into your puncture kit

11. Always carry a valve key handy because you need to remove the valves to facilitate better airflow. Leaving the valves in place defeats the object as the valve restricts airflow. However, when not using two compressors, the un-used tube needs to have the valve in place to avoid air loss

12. Always keep this handy airflow booster fitting in your puncture kit – you never know when you may need it. This simple DIY tool will give you a lot of satisfaction and is easy to make. It is also just as handy for 4X4 vechcles.
