Pipe sizes are not what they sound like — the name is a nominal size, not the actual measurement. Knowing how to measure the diameter saves a trip back to the store with the wrong fitting.
The nominal size
A half-inch pipe is not half an inch across; the name refers to the pipe's nominal size, and the actual outside diameter is larger.
The measure
Measure the outside diameter with calipers or a tape, then match it to a pipe-size chart for the material.
The thread
Threaded fittings are measured by their nominal size, and the threads must match the pipe exactly.
The tip
For a quick match, take the old part to the store rather than trusting a guess. hard water and humid conditions are common, and coastal salt air accelerates corrosion on fittings In Jacksonville, a pro always matches the exact size.
The chart
Measure the outside diameter and match it to a chart for the material, because copper, PEX, and PVC all size differently. The nominal size is not the measured size.
