I need a test point coupling for some hydraulic work, and I keep seeing different part numbers for this Stauff Test 20. What's the deal with all the alternate numbers listed?

Answer by: Customer Support on Feb 16, 2026, 6:26 AM

Those alternate part numbers simply reflect different ways the coupling might be designated, sometimes due to packaging or slight variations in how distributors label them. They all refer to the same Stauff Test 20 Coupling with a G1/4 thread and Viton seal.
