Meters that are 1.5 and 2 inches in size most commonly use which type of pipe coupling?

• A. Flanged pipe couplings
• B. Compression fittings
• C. Slip-on couplings
• D. Threaded couplings

Answer: (A)

For larger-diameter meters, joints need to be strong, reliable, and easy to service. Flanged connections provide a bolted, gasketed seal that can handle higher pressures and loads, and they make it straightforward to disconnect the meter for maintenance or replacement. That combination of strength, leak-tightness, and serviceability is why flanged pipe couplings are the most common choice for 1.5- and 2-inch meters. Smaller or alternative connection types—compression, slip-on, or threaded fittings—are typically used on smaller pipes or in situations where the piping ends and requirements differ, but they don’t reliably meet the needs of larger meter connections.
