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 JP4-01 pneumatic 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!
