Installation

The Injection Fitting is designed to install directly into either 1/4″ or 1/2″ female pipe threads (NPT).

You can trim the injection point (nose) if needed.

The nose section is designed to inject the chemical away from the wall of your pipe.

We do offer another Injector Fitting for smaller pipe sizes (such as 1/2″ and 1/4″). This fitting does not have the same length at the injection point (nose).

Two Installation Options:

Install the Injection Fitting directly into a tee fitting

  • The solution must inject directly into the flow stream.
  • Use PTFE® thread sealing tape on the pipe threads of the Injection Fitting.
  • This illustration shows the Injection Fitting installed in a tee fitting using the 1/2″ threads.
