Used for mud rotary drilling, the hollow stem wash tee has a pipe thread coupling located on the side of the tube (2″ NPT on the smaller sizes and 3″ NPT on the larger sizes). Wash Tees have tool joints that are the same as the auger string. We can supply special tool joints to meet your specific needs or lengths as required. Standard length is 18″ (457 mm) shoulder to shoulder and the Wash Tee coupling is located 6″ below the top tool joint connection.
