When you’re connecting 3-inch hydraulic lines on your big equipment, you need a coupling that won’t let you down during harvest or planting season. Whether you’re running a large combine, high-capacity manure spreader, or heavy-duty tillage equipment, this galvanized coupling creates a solid, leak-free connection between pipes or hoses that handle the high-pressure demands of modern farming.

What You’re Getting

  • Female NPT threads on both ends for easy connection to standard 3-inch pipe and fittings
  • Hot-dip galvanized finish that resists rust and corrosion even in wet field conditions
  • Heavy-duty construction designed to handle the pressure and vibration of agricultural hydraulics
  • Standard NPT threading that works with existing pipe systems and fittings

Built for Real Farm Work

This coupling is sized for the big hydraulic systems found on combines, large tractors with high-capacity loaders, and stationary equipment like grain handling systems. When you’re moving thousands of gallons per hour through irrigation systems or handling the hydraulic demands of a 12-row planter, you need connections that keep up with the flow without creating pressure drops or weak points.

Made to Last

The galvanized coating isn’t just for looks—it’s your protection against the rust and corrosion that comes from exposure to fertilizers, chemicals, and constant moisture. This coupling is built to the same standards as the fittings that come on your equipment from the factory, so you know it’ll hold up to years of hard use.

Installation Notes

Thread both connections hand-tight first, then use pipe wrenches to snug them down—don’t overtighten and risk cracking the threads. A little pipe dope or thread sealant on the male threads ensures a leak-free connection that you can count on. Make sure to support the weight of connected pipes so the coupling doesn’t carry the load.
