Retractable Injectors/Diffusers

Retractable Injection Quill – 100 psi rated

These injectors are for water mains where pressures do not exceed 100 psi.*

With caution, operators can safely remove and insert the PVC or CPVC solution tubes for inspection or replacement purposes, while the main remains in service. No shutdown is required.

A single stainless steel hook and chain locks the solution tube securely to the main connection.

A stainless steel limit chain will stop the solution tube from extending past the main connection during withdrawal.

The solution tube adapter and packing nut thread together, compressing the 300 series o-ring. This forms a tight seal around the outer diameter of the solution tube.

* We do not recommend or warranty PVC or CPVC solution tubes when velocities in the water main exceed 6 fps.
