Stucchi Coupler Part Numbers: A-Series, FIRG & IRB Size Guide
Most Stucchi couplers are flat face (common on skid steers). The size is the number in the name. Example: A13 or FIRG13 = 1/2". Find the part number stamped on the metal body of your coupler and type it in the box below, or use the chart. No number? Measure it instead.

- ✓Use the number stamped on the metal body of the coupler, not the hose. Hose printing (SAE 100R2, PSI, W.P.) won't match.
- ✓No part number? Measure across the male end (the plug, not the female socket) and type it, like 24.5 mm or 0.96 in. See how to measure →
- ✓Dashes, spaces and capitals don't matter (M-A13 = ma13).
- ✓Can't read the whole number? Type the first few characters you can see.
