The actual product may differ slightly from the image.
Tee or L-shaped DILO tube unions allow flexibility in tubing construction. Both versions are available with weld-on end for applications where highest vibration resistance is required or combined with a Whitworth screw-in thread which enables more variability in use.
Temperature resistance from -270 °C up to +500 °C, depending on the material used.
Advantages & functions
- With two weld-on ends and one screw-in thread
- Available for tube diameters from DN 3 up to DN 50
- Temperature-resistant from -270 °C up to +500 °C (dependant on the material used)
- Also available in other DIN EN materials
- Five-part union consisting of 2 weld-on stubs, 2 clamping nuts and 1 screw-in Tee piece
