The 3/4 in. x 3/4 in. Brass Hose Barb x Male Garden Hose 2 in. Shank Adapter is a brass garden hose (GHT) fitting. NPSM (National Pipe Straight Mechanical) shanks are the threaded inserts used inside swivel hose couplings — the shank threads into the coupling body and the barbed or serrated end grips the hose ID. Long and short shank lengths accommodate different hose wall thicknesses. 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.

|---|---|
| Material | Brass |
| Thread Standard | GHT (3/4 in. Straight, 11.5 TPI) |

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.
