Booster line sections are equipped with which type of couplings?

• A. Bolt-type couplings
• B. Pin-type couplings
• C. Screw-on couplings
• D. Push-fit couplings

Answer: (B)

Booster line sections are built for quick, reliable connections in tight, fast-moving firefighting situations. A pin-type coupling, often called an instantaneous coupling, uses a simple pin to lock the two hose halves together. This design lets you connect or disconnect rapidly, even with gloves on, and keeps the halves aligned so the gasket seals properly. Speed and dependability matter most with booster lines, so this quick-lock system is ideal. Other coupling types require threading or additional steps that slow things down or risk cross-threading, and push-fit options don’t provide the same secure, locked connection under pressure. That’s why pin-type couplings are used for booster line sections.
