Built for Real Diagnostic Work
This coupling is designed for tractors, combines, and other agricultural equipment where hydraulic troubleshooting is part of regular maintenance. Whether you’re checking system pressure, diagnosing flow problems, or setting up hydraulic circuits, this port gives you a professional connection point that works with standard diagnostic gauges and test equipment.
Made to Last
Farm hydraulic systems aren’t gentle on components, and diagnostic equipment gets moved around a lot. This coupling uses quality materials and tight tolerances to maintain its seal under pressure and keep working reliably through countless test connections. The 6,000 PSI rating means it’ll handle whatever your hydraulic system can throw at it.
Installation Notes
Installation is straightforward—just thread it into your test port using proper hydraulic thread sealant. The push-to-connect feature means your gauges and test equipment hook up with a simple push and pull apart just as easily. Keep a dust cap on the coupling when not in use to prevent contamination from getting into your hydraulic system.
