Ifp needle charging adapter | (Prototype) Available Soon

This adapter lets you charge the IFP or bladder chamber through the rubber plug / pellet using a standard hypodermic needle, with no proprietary needle assembly required.

The body is CNC machined stainless steel for durability, with a copper extender carrying a standard Schrader valve thread so the threads on your pump or filling tool stay protected.

The needle interface is a 3D printed press fit designed for common medical needles, so replacements are cheap and available almost anywhere in the world. A cap is included to keep the adapter clean between jobs.

Needles are not included. Shipping needles internationally is complicated.

Use standard hypodermic medical needles in 23 gauge (blue) or 22 gauge (black).

They are sold everywhere and they are cheap. Boxes of 100 typically run around $15 CAD on Amazon or from any pharmacy or farm supply store.

Because the needle is a consumable, you can swap in a fresh one whenever the tip dulls instead of replacing the whole tool.

• Press fit a fresh needle onto the printed interface
• Thread the adapter onto your shock pump or filling tool
• Insert the needle into the centre of the pellet while rotating it gently, never forcing it
• Inflate slowly to your target pressure
• Pull the needle out quickly and immediately snug the pellet
• Cycle the shaft to confirm it returns smoothly.

Never bend the needle. Rotating gently on the way in is what keeps the tip straight and the pellet undamaged.
