The 3/4 in. x 1/2 in. Brass Male Garden Hose x Female NPT Adapter (30068) is a brass garden hose (GHT) fitting. Garden hose thread (GHT) × NPT adapter connects standard garden hose to NPT-threaded pipe, valves, and equipment ports. Garden hose thread (GHT) is a straight 3/4 in., 11.5 TPI thread sealed by a rubber washer — not the tapered thread seal of NPT. GHT and NPT are not interchangeable and will cross-thread if mixed.
Technical Specifications
| Specification | Value |
|---|---|
| Material | Brass |
| Thread Standard | GHT (3/4 in. Straight, 11.5 TPI) |
| Seal Method | Rubber washer (GHT side) |
| Note | GHT and NPT are NOT interchangeable — different thread form and pitch |
Key Features
- Brass construction — outlasts plastic garden hose fittings in UV, freeze, and thermal exposure
- GHT (3/4 in., 11.5 TPI straight) — compatible with all standard U.S. garden hose couplings
- Rubber washer creates the pressure seal — replace washer if fitting leaks at hand-tight
- GHT is NOT compatible with NPT threads — verify thread type before assembly
- Male GHT mates with female hose coupler; female GHT mates with male hose bib or male garden hose fitting
Common Applications
Connecting flexible hose to garden hose bibs and irrigation equipment, converting NPT-threaded valves and equipment to accept garden hose connections, hose repair and splicing, and manifolding or branching garden hose lines.
