What the AI looks for in Garden Hose Parts & Connectors

Thread standard: In the US, garden hose fittings use GHT (3/4 inch, 11.5 TPI, also called NH). GHT does not seal with NPT pipe thread. Many other regions use BSP or click-on systems. Mixed thread standards are the most common reason a fitting leaks or will not thread on.
Hose inner diameter for menders: Match the mender or replacement coupling to the hose's inner diameter, commonly 1/2, 5/8 or 3/4 inch. A mender that is the wrong size blows off under pressure or will not insert.
Male versus female end: The spigot and hose outlet are male. The hose inlet end is female. Buying the wrong gender is a common return reason.
Material: Prefer solid brass or anodized aluminum. Be cautious with die-cast zinc and thin plastic for anything left under pressure. Zinc corrodes and cracks, and plastic threads strip.
Washers: Female couplings need a rubber washer seated inside. Replace a hardened or missing washer before buying new parts. Most hose connection leaks are a washer problem, not a fitting problem.
Quick connect compatibility: Stay within one quick-connect system, because plugs and sockets from different brands may not mate reliably. Quick connects are not universally interchangeable.

Not reliably. GHT and NPT share a similar diameter but have different thread pitch and form, so you need a GHT to NPT adapter.
