When you’re out in the field during harvest season, the last thing you need is a hydraulic coupling that leaks or won’t connect properly when you’re trying to hook up your header. This 3/8 inch hydraulic quick coupling fits with SMA 730-0004042 3/8 Header Coupling and keeps your combine running smoothly when every hour of good weather counts.
What You’re Getting
- 3/8 inch size designed specifically for combine header hydraulic systems
- Quick-connect design that lets you hook up headers without fighting stubborn threaded connections
- Pioneer quality construction that handles the constant pressure changes of combine hydraulics
- Direct replacement that connects to existing header couplings without modifications
Built for Harvest Work
This coupling is designed for the demanding world of combine operations where headers need to be connected and disconnected quickly and reliably. Whether you’re switching between different headers for corn, soybeans, or grain, or dealing with the hydraulic connections that control header functions like reel speed and cutterbar height, this coupling makes those connections fast and leak-free.
Made to Last
Combine hydraulics work hard during long harvest days, with constant pressure cycling and exposure to dust, chaff, and weather. This Pioneer coupling is built to handle those conditions with quality seals and robust construction that keeps working when you need it most.
Good to Know
This coupling works as part of a matched set with the corresponding header coupling, so both sides connect smoothly without binding or leaking. Always clean the coupling faces before connecting to keep debris out of your hydraulic system, and check connections periodically during harvest for any signs of wear or leakage.
