NPT Hose Barb Fittings

These adapters are all designed to connect a rubber hose to an NPT port. They are recommended for low-pressure (50 psi max) applications such as carbureted fuel systems and cooling systems.

Find NPT to AN adapters on our NPT Plumbing Adapters page.

Note: NPT nomenclature can be confusing because the nominal size refers to the inside diameter of the pipe, not the outside diameter of the threads. For more information, check out our Guide to Using NPT Fittings.
