🔍 Key Concepts

• fire hose coupling components (male outlet, female coupling, gasket) • importance of a watertight seal when connecting firefighting equipment • what conditions can cause leaks or loss of pressure in a fire hose line

💭 Think About

• Before water is turned on, what must be in place inside the female coupling to prevent water from spraying or leaking at the connection? • Which option is absolutely necessary at the hydrant connection itself, and which options could be done earlier or later without stopping the connection from working? • Think about which choice, if missing, would immediately cause loss of pressure or dangerous leakage at this specific joint.

✅ Before You Answer

• Identify the part inside the female coupling that actually makes the seal against the male outlet. • Ask yourself which answer choice deals with sealing the connection, not just convenience or hose handling. • Consider standard hose couplings: they are designed to work without extra lubrication and with or without the nozzle already attached.
