Description

If you’ve noticed hydraulic fittings backing off or developing leaks around the hydraulic couplers on your New Holland tractor, this ring nut might be just what you need to button things up tight. It’s a threaded retaining nut that keeps hydraulic fittings properly seated and prevents them from working loose during operation—something that happens more often than you’d like when you’re running implements hard.

What You’re Getting

Precise M45 x 1.5 metric threads that match factory specifications exactly
Heavy-duty construction designed to handle hydraulic system pressures and vibration
Proper thread engagement prevents fittings from backing off during operation
Direct replacement for worn or lost ring nuts in hydraulic coupling assemblies

Built for Real Farm Work

This ring nut fits a comprehensive range of New Holland tractors, from the smaller T5 utility machines perfect for hay and livestock work, up through the TM series powerhouses that handle heavy tillage and large implements. Whether you’re running a T5.95 with a rotary cutter or pushing a TM190 through tough field conditions, reliable hydraulic connections are what keep you working when there’s a job to finish.

Made to Last

Hydraulic fittings take constant abuse from pressure cycles, temperature changes, and the constant vibration that comes with tractor work. This ring nut is built from materials that resist thread wear and maintain proper clamping force season after season, keeping your hydraulic connections sealed and secure.

Installation Notes

Thread this nut by hand first to avoid cross-threading, then tighten with the proper wrench. If you’re replacing it, clean the threads thoroughly and check that the fitting seats properly before final tightening. Keep a spare in your tool box—these small parts have a way of disappearing when you need them most.
