Note
- 2 inch NH / NST is very rare and is often mistaken in place of 1.5 inch NH / NST. When measuring, always try to measure the male coupling! The majority of customers who order 2" NH / NST need 1.5" NH / NST. If you have a fire department connection, hose, or an adapter, check the female coupling for numbers or letters. Most 2.0 inch hoses use 2.0 inch NPSH couplings.
The outside diameter of a 1.5 inch NH / NST male hose coupling or fire hydrant is 1.99 inches. The outside diameter of a 2.0 inch NH / NST male hose coupling or fire hydrant is 2.515 inches. The outside diameter of a 1.5 inch NPT or NPSH male hose coupling is 1.878 inches. The outside diameter of a 2.0 inch NPT or NPSH male hose coupling is 2.352 inches.
