Frequently Asked Questions
Q: What tube diameter is compatible with this Bowden Y Connector?
A: This PC4-10 pneumatic fitting is designed for PTFE tubes with a 4mm outer diameter (OD), which is the standard size used by Bambu Lab printers and most desktop FDM 3D printers. Always verify your tube's OD before purchasing.
Q: Is the Bambu Lab Y Connector Bowden Coupler easy to install?
A: Yes! This is a push-fit pneumatic connector — no tools or assembly are required. Simply push your 4mm OD PTFE tube firmly into the fitting until it locks in place. To release, press down on the collet ring and pull the tube out.
Q: Can I use this connector with printers other than Bambu Lab?
A: Absolutely. While optimized for Bambu Lab setups, this PC4-10 Y connector is compatible with any Bowden-style 3D printer that uses standard 4mm OD PTFE tubing, including Creality Ender, Prusa, and similar machines.
Q: How many connectors are included in one order?
A: You can choose from a 1-piece, 2-piece, or full set option at checkout, so you can stock up on spares or grab exactly what you need for your upgrade project.
