Add to cart Download data sheet Legacy online catalogue

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 weld-on end (adjustable)
Available for tube diameters from DN 3 up to DN 40
Temperature-resistant from -270 °C up to +500 °C dependant on the material used (At operating temperatures below -197°C, additional tests must be carried out on the raw material in accordance with the specifications of EN 13445 / AD200 to ensure material integrity and suitability.)
Also available in other DIN EN materials
Six-part union consisting of 2 weld-on stubs, 2 clamping nuts, 1 screw-in stub and 1 Tee swivel piece
