Angle screw-in unions with Whitworth thread

M1BW25G D

Elbow DILO tube unions can be used for 90° angles. Angle unions are available with weld-on ends for applications where highest vibration resistance is required. They are also available with weld-on end and Whitworth screw-in thread.
Throttle-free swivel unions allow positioning of the weld-on end as per your requirements. Thus, any tubing can be established, no matter how complex they are.
Temperature resistance of all unions from -270 °C up to +500 °C, depending on the material used.

Advantages & functions

  • With weld-on end and screw-in thread
  • 90° angle
  • 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 (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.)
  • Available for pressures up to 1.000 bar on request
  • Also available in other DIN EN materials
  • Three-part union consisting of weld-on stub, clamping nut und screw-in angle
