The GREEN LEAF B 3458 W is a female hose to barb adapter designed for connecting standard garden hose threads to barbed tubing fittings. Molded from nylon, this adapter accepts a 3/4 inch female garden hose thread (FGHT) on the inlet side and terminates in a 5/8 inch barb on the outlet side. The barb end is designed to accept flexible tubing or hose. At 0.031 pounds, the fitting is lightweight and corrosion-resistant, making it well suited for irrigation, water transfer, and general fluid-handling applications. Plumbers, irrigation technicians, and experienced DIYers typically work with this fitting type.
This adapter is appropriate for residential and light commercial applications where a garden hose threaded supply needs to transition to barbed tubing. Common install scenarios include drip irrigation assemblies, pond and fountain plumbing, portable water transfer setups, and general outdoor plumbing tasks where a threaded hose connection must mate with flexible tubing. The nylon construction holds up well against moisture and mild chemical exposure in outdoor environments.
Designed as a standard-style replacement or new-install fitting for applications using 3/4 inch female garden hose thread (FGHT) connections transitioning to 5/8 inch barbed tubing.
Installation is typically performed by plumbers, irrigation technicians, or qualified service professionals. Turn off the water supply completely before making or breaking any connections. Thread the FGHT female end onto the male hose thread fitting by hand first, then snug as needed — avoid overtightening nylon fittings as this can crack the body. Ensure the barbed end is fully seated into the tubing and secured with an appropriate clamp to prevent blowoff under pressure.
