Metric & Imperial Hose Plugs

These tapered hose plugs are designed for easy insertion and removal when you want to stop leakage from a disconnected device. They are hose/tube plugs for the most common metric and imperial sizes. The plugs are not tapered along their entire length: the last few millimeters near the handle are straight with 3 rings to keep it in place and watertight. I also set the seam placement to random to avoid a continuous rib that could cause leaks. For easy removal, simply turn the plug anti-clockwise and pull (see GIF). They work best with flexible hoses. I used PLA because it is sufficient for my project (see picture of the dehumidifier), but if you need more strength or better fluid resistance, you could use PETG, ABS, etc. I printed all metric sizes on one build plate without using a brim (see picture), but if you experience bed adhesion issues, use the print profile with an added brim. All plugs (metric and imperial) have their size number printed on the handle (see picture). I tested these plugs on all types of hose sizes I had at home and left them installed for several days to check for leakage. They proved to be watertight (see picture). 

Note: Not designed for pressurized systems. You may test it on a pressurized system using a hose clamp, at your own risk. If you are not sure what your inner hose diameter is, print a few that come close to it and use the one that fits the tightest.

All sizes refer to the hose inner diameter (ID).

Metric sizes are:  2.5mm - 3mm - 3.5mm - 4mm - 4.5mm - 5mm - 5.5mm - 6mm - 6.5mm - 7mm - 7.5mm - 8mm - 8.5mm - 9mm - 9.5mm - 10mm - 11mm - 12mm - 13mm - 14mm - 15mm - 16mm - 17mm - 18mm - 19mm - 20mm

Imperial sizes are:  1/8 - 3/16 - 1/4 - 5/16 - 3/8 - 1/2  - 5/8 - 3/4  - 1" - 1"1/4  - 1"3/8 - 1"1/2  - 1"3/4  - 2"

The printprofiles i added are:

• Metric all sizes one plate (No Brim)
• Metric all sizes one plate (With Brim)
• Metric each size own plate (No Brim)
• Metric each size own plate (With Brim)
• Imperial all sizes one plate (No Brim)
• Imperial all sizes one plate (With Brim)
• Imperial each size own plate (NO Brim)
• Imperial each size own plate (With Brim)

Filaments used:

• Generic PLA

Printer details:

• Created on a Bambu Lab A1
• Printed with a 0.4 mm Stainless steel nozzle
• Build plate: Textured PEI Plate
• Make sure the build plate surface is clean before printing to ensure the best adhesion or use the printprofile with the added brim
