I have several underground pipe that I have to connect too. Any suggestions on what connectors to use?
anyone know which connector this is?

Much more info is needed.

What are you connecting, and why?

What size of pipes?

Threaded ends or not?

Pressurized or drainage?

Sewage or fresh water or rainwater or grounwater?

Pictures would help also.
