These new stainless steel injection barbs allow you to create your own EZ-FLO installation coupler. They can also be used to replace the barbs on pre-built installation couplers.
When installing the EZ-FLO steel injection barbs, whether replacing the stock ones on an EZ-FLO pre-built coupler or creating your own, make sure that the tapered ends of the barb inlet face outward, as indicated in the image below. This allows water to flow into and out of the injection barbs with ease. There is a circle imprinted on the molding on the beveled side of the barb for easy identification. Failure to install properly will cause the EZ-FLO fertilizer injector to not function properly.
To install the EZ-FLO steel injection barbs into a PVC fitting or pipe, drill a hole using a 5/16" bit and tap the hole with 1/8 NPT threads.
Note: Use a drill bit designed for plastic, standard wood bits will shatter PVC.
