🔍 Key Concepts

• Fire hose couplings and how male vs. female ends are arranged • The specific purpose of a spanner wrench in tightening/loosening hose connections • How a hydrant outlet and a hose coupling normally mate together on a fire main system

💭 Think About

• Think about which parts of the hose connection are actually designed to be turned with a spanner wrench—are they the same on male and female ends? • Consider how hoses are normally joined together in series. Which combination of ends would need a tool to get a tight, leak‑free seal? • Picture the shape of a fire main hydrant outlet versus hose couplings—would you normally put a spanner on the hydrant body itself or on the hose ends?

✅ Before You Answer

• Identify which hose ends (male or female) have lugs or projections for a spanner to grip. • Verify which components are normally fixed (don’t turn) versus which are meant to be tightened and loosened with tools. • Make sure the option you choose involves parts that realistically can be rotated against each other to tighten the connection with a spanner.
