Description
When you’re putting together hydraulic lines for your tractor or implement, you need connections that seal tight and stay that way. This Parker Ferulok fitting connects a 3/8-inch hydraulic hose to a 3/4-inch female thread, giving you a leak-free connection that swivels to make installation easier—no fighting with rigid connections when space is tight.
What You’re Getting
- Swivel design lets the hose rotate freely, reducing stress and making connections in cramped spaces much easier
- Flareless Ferulok technology grips the hose from the inside, creating a stronger seal than traditional flare fittings
- Female thread end connects to male ports on valves, cylinders, and other hydraulic components
- Straight configuration keeps the hose path clean and simple
- Professional crimping required—no field assembly, but creates the strongest possible connection
Built for Real Farm Work
This fitting works on any equipment where you need to connect 3/8-inch hydraulic hose to a 3/4-inch threaded port. You’ll find these sizes on loader valves, remote cylinders, and auxiliary hydraulic circuits on mid-size tractors. The swivel feature is especially handy when you’re working in tight spots or need the hose to move with implement operation.
Made to Last
Parker’s Ferulok system has been the gold standard for hydraulic connections for decades. The fitting body handles the high pressures and temperature swings that come with hydraulic work, while the crimped connection stays secure through thousands of pressure cycles and machine vibration.
Good to Know
This is a crimp-on fitting that requires the proper Parker crimping dies and equipment for installation. The crimping process permanently attaches the fitting to your hose, creating a connection that’s actually stronger than the hose itself. If you don’t have crimping equipment, most hydraulic shops can assemble these for you.
