Which brands are used for 1.75-inch and 2.5-inch hoses?

• A. Gladiator and N-Dura
• B. Gladiator and Waterlog
• C. N-Dura and Hard Suction
• D. Gladiator and Hard Suction

Answer: (A)

Hose brands are often linked to specific diameters because each size has different handling needs and typical uses on the fireground. For the 1.75-inch line, Gladiator is a common choice because its light weight and good kink resistance make a small, maneuverable attack line easier to advance and control. For the 2.5-inch line, N-Dura is a durable option that handles higher flows and longer lays well, balancing strength and flexibility for a larger-diameter supply hose. Other brands mentioned either correspond to different hose categories or aren’t the standard pairing for these sizes, so the combination of Gladiator for the 1.75-inch and N-Dura for the 2.5-inch hoses best fits how these sizes are typically equipped.
