Apache garden hose adapters eliminate threaded hook-up. Adapters create a quick and easy "tool-free" connection to 3/4-inches garden hose threaded attachments. Easy to install/operate with full-flow water design. Adapters simply thread onto nozzle, garden hose, or into machinery and accessories. 3/4-inches female garden hose thread x 1/2-inches female socket (with a recessed washer for a no leak fit) and a 3/4-inches male garden hose thread x 1/2-inches male plug. Note: make sure gaskets are in place on hoses and accessories to ensure a leak-free connection.
