5-Piece 3-Way Push-In Pneumatic Tee (for 4 mm tubing) Key benefits Tool-free, rapid installation and removal: Push-in design and quick-release collars let you connect or disconnect tubing in seconds. Space-saving T-branch: 3-way configuration creates a compact, reliable branch without extra fittings or tubing runs. Fast reconfiguration and maintenance: Quick-release feature simplifies system changes and troubleshooting. Reliable everyday performance: Secure push-in connection delivers a consistent seal for low to medium pressure pneumatic systems. Pack of five: Multiple tees included for small projects, spares, or staged installations. What it does and where it fits Function: 3-way union (tee) for splitting or branching air lines. Compatibility: Accepts tubes with a 4 mm outer diameter; works with standard 4 mm pneumatic tubing. Configuration: Push-in connectors with quick-release collars for fast tool-free operation. Application: Designed for air fittings in plumbing and pneumatic circuits where low to medium pressure performance is required. Practical use scenarios Split one compressed air supply to feed two small actuators in a compact automation module. Branch a shop air line to power two handheld pneumatic tools without adding bulk. Build a quick test rig or prototype pneumatic circuit that can be reconfigured repeatedly without tools. Important note Verify your system’s pressure rating and confirm tubing compatibility before installation to ensure safe, reliable operation.
