Good Quality but Tight

The build quality is solid, but the tube insertion was a bit tight initially. Once seated, it holds air pressure very well.

Excellent Value for Money

Durable brass construction at a great price. I bought these as spares and ended up using them on both of my printers.

Works but Instructions Unclear

The product works fine, but I wasn't sure if I needed Teflon tape on the threads. Ended up working without it, but some guidance would help.

Solved My Airflow Problems

Much better than the plastic connectors that came with my printer. No leaks and handles the heat near the hotend without deforming.

Perfect Fit for Remote Cooling

These fittings solved my heat creep issues by allowing me to move the fan further away. The brass quality is excellent and the connection is secure.

5 FAQ

Q: Will this melt near the heater block?

A: The brass material is heat resistant up to 200°C, but we recommend maintaining some distance from the heater block.

Q: Do I need any tools to install the tube?

A: No tools are required for the tube connection; it is a push-to-fit design. You may need a wrench for the threaded inlet.

Q: What is the thread pitch on the inlet?

A: The inlet features a standard M6 x 1.0mm thread pitch commonly used on hotends.

Q: Is this compatible with 3mm pneumatic tubes?

A: No, this fitting is specifically designed for 4mm Outer Diameter pneumatic tubes.

Q: Can this handle high pressure air assist?

A: Yes, it is rated for standard air assist pressures, though we recommend staying under 80 PSI for optimal safety.
