Items "B" and "D" are shown installed on the service gauge manifold set shown in figure "C", but are not present on the service gauge manifold set in figure "A" even though it is equipped to receive them. What are the devices "B" and "D"? See illustration GS-RA-31.

🔍 Key Concepts

• Look closely at how items "B" and "D" would connect between the manifold body and the refrigerant hoses • Think about common refrigeration service manifold accessories used to make fast, leak‑tight connections to system service ports • Compare the shapes of B and D to typical valves, reducers, and hose fittings used in HVAC/R work

💭 Think About

• Which option describes a device that lets you snap a hose on and off quickly without threading it every time? • Do B and D look like something that would actually puncture (pierce) tubing, or more like something that simply opens/closes flow when pushed onto a fitting? • If the manifold in figure "A" is "equipped to receive them," what does that suggest about the threads or connection type on the ends of the manifold and what B and D must be designed to do?

✅ Before You Answer

• Confirm which choice names a fitting used for fast connection/disconnection of hoses on refrigeration systems • Eliminate any options that would require electrical wiring or electronic components (do you see any on B or D?) • Eliminate options that are designed to change line size or puncture tubing, and focus on what B and D visually appear to do when mated with the manifold in figure "C"
