This page represents the adapters that we stock.  Many other configurations, styles and threads are available on a special order basis. 

To find your adapter, first click on the picture that represents your needs.  That will take you to the correct table of adapters.

Adapters that have fire hose threads on both ends will be highlighted in yellow.

Adapters that are not highlighted in yellow will have tapered iron pipe threads on one end and fire hose threads on the other.

Please Note:  3/4" NST is also known as Garden Hose Thread (GHT)
