Close the circuit properly. The Gardheaven RACCFL3/8 fitting is a blind end cap designed for 3/8-inch tubing and allows you to complete a branch of the system with a compact and reliable finish.
It is used when the line ends without being closed into a loop or connected to other components. By sealing the end of the tube, it prevents fluid leakage and allows the circuit to be pressurized according to the intended configuration. Its compact size helps keep the terminal point neat, even when it is mounted on structures, fences, or inside a utility compartment.
The quick-connect fitting simplifies installation and reduces installation time. For a proper seal, the 3/8-inch tube must be cut perpendicular to the end, free of burrs, and inserted all the way. It is also important to secure the line nearby to prevent weight, tension, or vibrations from putting strain on the fitting.
RACCFL3/8 is designed for use with compatible Gardheaven systems and must be used with the piping and operating pressure specified in the design. A leak test of the end branch is always recommended before startup.
It can be used in new installations, expansions, or maintenance projects, and if the circuit is modified, it allows a section to be temporarily or permanently disconnected. A small, unobtrusive connector—yet essential for the line’s functionality and organization.
