Read the two ends you are joining
Almost every garden hose question is really a threading question. Look at the end in your hand: if the threads are on the outside, it is male; if the threads are inside the collar, it is female. A hose end is always female, a spigot is always male. Once you know both ends, the fitting you need is simply the one that presents the opposite of each.
Joining, closing and routing GHT connections
| Your problem | The brass part that fixes it |
|---|---|
| Two hose ends, both female | Male to male adapter — joins hose to hose, or hose to spigot via a coupler |
| Two male ends | Female to female adapter |
| An open outlet that drips | Hose cap or plug — cap for a male end, plug for a female |
| Hose kinking right under the tap | Garden hose elbow, so the hose turns instead of folding |
| Hose twisting as you thread it on | Swivel adapter, which spins the joint instead of the hose |
| Swapping nozzle and sprinkler all day | Quick-connect fittings — one click instead of screwing |
Stepping out of GHT: barb, PEX, drip, M22, pressure washer
| Other system | What the adapter does |
|---|---|
| Barbed tubing 3/8" – 3/4" | Takes a garden hose down to soft tubing for drip, misting and hose repair; the tubing pushes on and a clamp holds it |
| PEX B/C | Connects a garden hose to PEX supply tubing, indoors or out to a faucet |
| 1/4" irrigation tubing | Feeds a drip or micro line from a standard hose tap |
| M22 (pressure washer inlet) | Lets a garden hose feed a pressure washer without stripping the pump thread |
| Pressure washer outlet | Adapts the machine side back to a hose or wand |
Barbs seal on a clamp, not on threads — never leave the clamp off, because a barb alone will pull out under pressure. Threaded fittings seal on the gasket, so tighten by hand and stop.
Why brass holds up where zinc does not
Garden hose thread is coarse and shallow, and it is designed to be hand-tightened hundreds of times a season. Softer metals deform under that, and once the thread flattens it leaks no matter how hard you turn. Machined brass keeps its shape, and it will not crack on the first hard freeze the way a die-cast body will.
Frequently asked questions
How do I know if a fitting is male or female?
Threads on the outside are male, threads inside the collar are female. A hose end and a nozzle inlet are female; a spigot and a hose outlet are male.
Do I need Teflon tape on these?
No. GHT seals on the rubber washer inside the coupling. Tape is for pipe thread (NPT) — and for that, use a pipe to hose adapter instead of forcing a hose onto pipe thread.
The joint still drips after I tighten it. Why?
Nine times out of ten the washer has gone flat and hard. Replace it with a fresh one from washers & gaskets before you blame the fitting.
A hose split in the middle — connector or new hose?
If the damage is within a few inches of the coupling, a repair kit will save it. A split in the middle of a long run is usually not worth patching.
