Description
The ST70 socket tongue is a cast iron line fitting with a socket at one end and a tongue connection at the other. The listed stock SKU is DULST70. This M16 option has a catalogue minimum failing load of 70 kN.

Connection and clip selection
The Dulmison catalogue specifies a W clip for the standard ST70 fitting. It lists an R suffix when an R clip is required. Therefore, contact our team if your drawing calls for a different clip arrangement.
This product is the straight socket tongue model. If your assembly needs a twisted tongue, provide the drawing or full part code so we can check the required orientation.
- Match the socket size to the ball connection.
- Check the tongue hole and mating bolt size.
- Confirm the required clip arrangement.
- Use the full DULST70 stock code when ordering.
The 70 kN value is a minimum failing load, not a working load limit. Use the approved assembly design to confirm suitability for the required duty.
