Injection Fitting (check Valve) 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. See image to the right.

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). See images to the right.

 

Install the Injection Fitting directly into a tee fitting.

The solution must inject directly into the flow stream.

Use TeflonŽ 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.

Injection Fitting

You can install the Injection Fitting directly into your pipe.

Drill the correct size hole and then tap the hole for 1/4" or 1/2" NPT.

Use TeflonŽ thread sealing tape on the pipe threads of the Injection Fitting.

This illustration shows the Injection Fitting installed directly into pipe using the 1/4" threads.

Injection Fitting

Cut an appropriate length of discharge tubing (opaque tube). Push one side of the tubing onto the compression barb of the Injection Fitting. Use the tube nut to secure the tube. Hand tighten only.

The exploded view drawing above shows the "tube nut" on the far right hand side. The part to the left side of the "tube nut" is the "compression fitting" that the tube must fit onto.

Cleaning:
The Injection Fitting (check valve) will require periodic cleaning, especially when injecting fluids that calcify such as sodium hypochlorite.

Available Injection fittings with 1" nose.
