The Rotojec body is the grout flushing housing of the Roto-Jec injection system: the shank turns inside it while grout enters through the stationary 1 in. female NPT connection and flows into the string. Three sizes cover the system 3 in. ID / 4-3/4 in. OD standard, 4 in. ID / 5-3/4 in. OD heavy duty and 5 in. ID / 6-3/4 in. OD super duty each including four double lip seals.
Built to hold injection pressure so grout reaches the crack, void or anchor hole instead of leaking at the joint, the body is made from durable, corrosion-resistant materials for moist or chemically aggressive underground conditions. Match it to the standard duty or heavy duty Rotojec shank, and keep replacement seals in the toolbox they are the wear item in the assembly.

Rotojec Body FAQ
Which body size do I need?
Match the body to the shank running through it: the 3 in. ID / 4-3/4 in. OD standard body pairs with the standard duty shank, the 4 in. ID / 5-3/4 in. OD heavy duty body with the heavy duty shank, and the 5 in. ID / 6-3/4 in. OD super duty body covers the largest string.
How does grout get into the string?
The shank rotates inside the body while grout enters through the stationary 1 in. female NPT connection, so the line stays put while the string turns the housing holds injection pressure so grout reaches the crack, void or anchor hole instead of leaking at the joint.
What is the wear item, and what ships with the body?
Each body includes four double lip seals, and the seals are what wear in service keep a set of replacement Rotojec seals on hand to stay pumping.
