What You’re Getting

- Compatible with most DEF transfer pumps for inlet and outlet connections
Built for Real Farm Work
DEF systems are found on just about every piece of modern diesel equipment—tractors, combines, trucks, and generators. This connection kit works with the DEF transfer systems you’ll find on farms and ranches, whether you’re topping off a single machine or running a bulk transfer setup. The 3/4 inch size fits most standard DEF hoses and pump fittings.
Made to Last
DEF is corrosive stuff, so these components are built to handle the chemical exposure without breaking down. The o-ring maintains its sealing properties even with temperature changes and regular use, while the barb fitting and clip resist corrosion from the urea solution.
Good to Know
Make sure your hose is clean before installing the barb fitting—any debris can prevent a good seal. The o-ring should sit flat in its groove, and the clip should snap into place with a firm click. Keep a spare set of these components handy since they’re wear items that will need replacement over time.
