The GREEN LEAF B 3412 W is a female hose-to-barb adapter designed to connect a 3/4-inch female garden hose thread (FGHT) fitting to a 1/2-inch barbed hose connection. Molded from nylon, this adapter provides lightweight, corrosion-resistant performance in irrigation, water transfer, and general fluid-handling applications. The threaded end accepts standard garden hose connections while the barbed end creates a secure friction fit with compatible 1/2-inch hose. Plumbers, irrigation technicians, and facilities maintenance professionals use this adapter when transitioning from threaded garden hose fittings to barbed hose lines.
This adapter is suited for residential and light commercial irrigation systems, outdoor water supply connections, and portable equipment hookups where a garden hose thread interface meets a barbed tubing run. It is a direct-install fitting requiring no specialty tools beyond standard hose clamps on the barb end to ensure a leak-free seal. The nylon construction makes it compatible with most non-aggressive water supply applications.
Designed as an OEM-style replacement and general-use adapter for applications using 3/4-inch female garden hose thread fittings transitioning to 1/2-inch barbed hose connections.
This fitting is typically installed by plumbers, irrigation technicians, or maintenance professionals. Hand-tighten the female hose thread end onto the male threaded port, then secure the barbed end with an appropriately sized hose clamp to prevent pullout under line pressure. Shut off the water supply fully before installing or removing the adapter. Avoid over-tightening the threaded connection on nylon fittings, as excess torque can crack the fitting body.
