Fire hose fitting specification

The Legend Valve 324-101 A80 is a 1-1/2 inch NST coupling designed for fire hose connections. It serves firefighters, maintenance crews and industrial facilities that require standard National Standard Thread compatibility. The part is supplied new and carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm.

Thread standard decides fit

The single specification that determines whether this is the correct part is the 1-1/2 inch NST thread size. Only hoses and equipment matching this exact thread standard will connect securely. No other thread type or diameter is compatible with this coupling.

Suits standard NST systems

This coupling suits teams that operate exclusively with 1-1/2 inch NST fire hose systems. Buyers who need a different thread standard, a different diameter or a non-fire-hose fitting should look at other options.

Questions about this item

What does the 1-1/2 inch NST size mean when I connect this coupling to a fire hose?

The 1-1/2 inch NST thread matches standard fire hose connections, so this coupling screws directly onto compatible hose ends and hydrant outlets without adapters.

How does the NST thread standard affect which hoses or equipment I can use with this fitting?

NST (National Standard Thread) is the common fire service thread in the US; this coupling will only mate with other NST-threaded components of the same nominal size.

What physical space or mounting arrangement does the 324-101 A80 coupling need for installation?

The coupling installs by threading onto a 1-1/2 inch NST male or female end; no separate flange, bracket or special tooling is required beyond standard fire hose spanner wrenches.
