About the hose and pipe adapter maker

Connect two hoses or pipes of different sizes, for shop vacuums, dust collection, pond pumps and more. Enter the two diameters and lengths.

  • Measure with calipers and print a short test ring first.
  • For vacuum hoses a slight interference fit holds without clamps.
  • A longer middle section gives a gentler, stronger transition.
