Will these drip parts work together?

Start with actual tube dimensions, then check the flow and pressure each component is specified to handle.

Work through one connection or component at a time. A matching dimension or operating range is one check; it does not approve a complete irrigation system.

01 / Compare the dimensions

Read the fitting’s matching tube range.

Use the fitting manufacturer’s stated range for the tubing it accepts. Measuring a barb’s widest point or entering only “½ inch” does not establish that range.

Tubing model
Tube outside diameter
0.63 in (16.002 mm)
Tube inside diameter
0.54 in (13.716 mm)
Fitting reference
Which matching tube dimension does the fitting specify?
Units on the fitting specification

For a single explicitly accepted diameter, enter the same value twice. Changing units converts your entries. Changing tubing keeps the fitting range so you can compare another tube.

Source notes and remaining checks
  • OD and ID are separate manufacturer table values; do not derive either from listed nominal wall thickness.
  • 70 psi is tubing rating, not recommended emitter pressure.
