Frequently Asked Questions

Q: What thread standards do these fire hydrant hose adapters use?

A: Each adapter features a 2-1/2" NST (National Standard Thread) / NH female inlet for connecting to a standard fire hydrant outlet, and a 3/4" GHT (Garden Hose Thread) male outlet for attaching a regular garden hose. This combination covers the most common hydrant and residential hose sizes in North America.

Q: Are these adapters suitable for garden irrigation and car washing as well as firefighting?

A: Yes. The adapters are designed for versatile high-flow water applications including garden and orchard watering, vehicle washing, and firefighting support. They are rated for pressures under 850 kPa, making them capable of handling high-demand outdoor water tasks.

Q: What is the advantage of the pin-type lug design over a swivel adapter?

A: Pin-type lugs stay fixed in place even when the connected hose is repositioned or under load. This prevents the adapter from unintentionally loosening or rotating during use, providing a more secure and reliable connection compared to standard swivel-style adapters.
