Converts the presta side of the dual sided head of a Park Tool Inf-2 to a Schwalbe Clik head. There are two versions currently available: 

  • V3 model uses assembled valve converter for easy use and installation, this model does not always create a perfect seal but valve converter is removable.
  • V4 model uses disassembled valve converter for better sealing capability and robustness, this model creates a perfect seal but cannot be easily removed from valve converter.

Uses a Schwalbe Clik Valve Conversion Set (NOT COMPATIBLE WITH PUMP HEAD KIT

Also requires:

  • Park Tool Inf-2 
  • 8mm hex wrench
  • PTFE Thread tape
  • 17mm Spanner (or adjustable)
  • Super glue (V4 only)

 

Installation instructions refer to park tool exploded diagram

V3 Directions:

  1. Print adapter at 100% infill, min 5 perimiters, max 0.2mm layer height out of a robust material
  2. Remove Presta Cap (13) from Inf-2 using 8mm hex
  3. Apply many layers (variable) of PTFE tape to printed adapter exterior threads
  4. Screw printed adapter into fill head (15) tightly by hand
  5. Apply ~3 layers of PTFE tape to Schwalbe pump adapter threads
  6. Screw Schwalbe pump adapter into printed adapter until snug
  7. If setup leaks in use, apply more tape

V4 Directions:

  1. Print adapter at 100% infill, min 5 perimiters, max 0.2mm layer height out of a robust material
  2. Disassemble the schwalbe converter, exposing the ~14mm threads and rubber grommet on the head. Be careful not to loose the grommet as it is essential.
  3. Loosely screw the schwalbe head into the adapter with grommet to verify the print was successful, it should sit as shown in images snug to the printed adapter body.
  4. Unscrew the schwalbe head from the adapter and apply two small dots of superglue to the threads. Then re-screw as before ensuring the rubber grommet is in place. Allow to dry.
  5. Remove Presta Cap (13) from Inf-2 using 8mm hex
  6. Apply many layers (variable) of PTFE tape to printed adapter exterior threads
  7. Screw printed adapter into fill head (15) firmly with 17mm spanner
  8. If setup leaks in use, apply more tape

Results may vary due to the nature of 3d printed components.
