6mm OD Push-Fit Fitting PT1/8 Thread

These brass-and-plastic fittings accept 6 mm OD tubing for 3 mm filament and use a PT1/8 thread. They connect an extruder to a PTFE tube in a 3D printer. The pack contains two pieces.

Who they suit and who they do not

Builders who need a quick-connect joint for 6 mm OD Bowden tubing with a PT1/8 port can use these. Users whose printer requires a different thread size or a different tube diameter cannot use them.

Deciding specification

The thread is PT1/8 and the inner diameter at the brass end measures 6.8 mm. If the printer’s hot-end or extruder uses another thread standard, the fitting will not install.

Questions about this item

Will the PT1/8 thread on these fittings match the extruder port on my older 3D printer?

The fittings use a PT1/8 thread size, so they will match any extruder or hot-end with the same thread specification.

How can I confirm the push-to-fit mechanism is gripping the PTFE tube correctly after installation?

Push the 6 mm OD tube into the blue end until it seats firmly; a gentle tug should not release the tube unless the blue release collar is pressed down.

The pack lists two fittings — are any lock nuts, sealing washers or extra PTFE tube included?

The package contains only the two brass-and-plastic push-to-fit fittings; lock nuts, washers and PTFE tubing must be sourced separately.
