This fitting converts a 50mm PVC pressure pipe into a hand dredge or yabbie pump, perfect for gold prospecting.

  • Materials: Use ABS or ASA compatible with PVC adhesive.
  • Handle Strength: Consider using TPU to enhance durability.
  • Instructions: Print 2 small spigots and glue them to both ends of a 20mm pipe for the inner part of the pump. Adjust the collar to set the piston height.
  • Glue one large spigot to one end of the 50mm pipe and let it cure for 24 hours.
  • Insert the piston into the inner pipe, then slide it into the outer pipe, and attach the handle and flange.

Follow the printing instructions for optimal results.
