Thread:
Whitworth-Pipe thread according to DIN / ISO 228-G
Type of thread:
Inner- and outer cylindrical thread
Application:
not for in thread sealing connections
This thread is mainly used for the mechanical connection of fittings and valves.
The connection is sealed by pressing two sealing surfaces against each other outside of the thread and by
inserting a suitable seal between them.
