The NH fire hose couplingis based on the NST thread standard and uses male and female ends in combination. It connects fire hoses to firefighting equipment such as water nozzles, fire pumps, and fire trucks through threaded connections.
When connecting the NH fire hose coupling to a hose, the hose is typically placed inside the tailpipe, and a copper ring is expanded outward to ensure a secure and stable connection.
