What it does and why you need it Tee Union for pneumatic systems that lets you branch one air line into two quickly and reliably. Ideal when you need to add a feed, split supply to multiple devices, or reconfigure tubing without cutting or complex fittings. Key benefits Fast installation: pushtoconnect design secures tubing without tools, reducing installation time and downtime. Versatile sizing: available in 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, and 16mm OD to match common pneumatic tubing and simplify inventory. Easy maintenance and changes: remove and reconnect tubing quickly for system changes or troubleshooting. Secure connections: engineered for a tight, repeatable fit with compatible OD tubing used in pneumatic applications. Function and compatibility Function: threeway Tee Union for splitting or joining pneumatic air lines. Compatibility: made for standard pneumatic tubing with outside diameters of 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, and 16mm OD. Use the matching OD size for proper sealing and retention. Installation: pushtoconnect fittings — insert tubing until it seats; pull to release when needed. Practical use scenarios 1. Production line: split a main air supply to operate two air cylinders from a single feed without adding complex manifolds. 2. Workstation setup: add a dedicated branch for an air tool or blowoff nozzle at a specific station while keeping the main line intact. 3. Maintenance and prototyping: rapidly reconfigure pneumatic layouts or a worn fitting onsite with no special tools. Performance notes Designed for quick, repeatable connections in pneumatic systems where speed and flexibility matter. Select the correct OD size to ensure proper fit and reliable operation. Use this Tee Union wherever you need a simple, fast, and sizematched way to branch pneumatic tubing in industrial, workshop, or automation applications.
