This is an excellent deal on a set of 12 quick-connect hose fittings. The set includes two female and two male hose end adapters plus eight tool connectors* – more than enough to completely outfit at least two hoses (with adapters used at both ends) plus all of your most-used watering accessories.
These are designed with a twist-lock mechanism for a secure, leak-proof link – the fittings won’t accidentally pop loose once connected. Additionally, the female hose end adapters have an internal valve that instantly stops flow when the fittings are disconnected, so you never have to kink the hose or shut off the faucet before changing watering equipment. For use on standard hose and tap fittings, all are tough polypropylene; the adapters have a textured coating on the release collars for grip.
* Six male-threaded and two female-threaded connectors, since you typically need more male fittings.
