Need to connect a garden hose to your kitchen or bathroom sink? This solid brass adapter makes it easy. It screws onto the end of your faucet where the aerator normally goes. Here's how it works: First, you need to remove your existing aerator from the faucet spout. This adapter has 55/64\-27 female threads, which is a very common size for faucet aerators. If your faucet has the slightly less common 15/16\-27 male threads, don't worry – the kit includes a small thread adapter for that too. Once it's screwed on, the other end has standard 3/4\ Garden Hose Thread (GHT), so you can attach any garden hose. A cool feature: it has a built-in aerator, so you can still use your faucet normally for washing dishes without the hose attached – the water flow will be aerated and non-splashing. When you *do* attach a hose, for maximum flow (like for filling buckets), you can temporarily remove the aerator insert. Made from solid brass, it's durable, rust-resistant, and won't leak if installed properly. Super handy for filling mop buckets, watering cans indoors, or connecting a portable washing machine. Just check your faucet threads first!
