Pneumatic connectors are commonly used with 3D printers to connect Bowden tubes to extruders and hot ends, providing a reliable, strong fitting with little to no movement of the tube once fitted.

This is a pack of five KJH-04-M6pneumatic connectors which accept Bowden tubes with a 4mm outer dimension (4mm OD) and 2mm inner dimension (2mm ID), such as the tubes we sell in the store.

We sell a number of other styles of pneumatic connectors – take a look in our 3D printing section for more!
