Description

When you’re dealing with water transfer on the farm—whether filling tanks, moving irrigation water, or setting up temporary lines—you need couplers that connect fast and seal tight. This 3-inch D series cam lock coupling takes the hassle out of pipe connections, letting you hook up to female NPT threaded fittings in seconds with just a twist of the cam levers.

What You’re Getting

Heavy-duty polypropylene construction that won’t crack or corrode like metal fittings
200 PSI pressure rating handles high-flow applications without breaking a sweat
Smooth cam lever operation—no wrestling with pipe wrenches or struggling with stubborn threads
Secure gasket seal prevents leaks that waste water and create muddy messes
Large 3-inch diameter moves serious volumes of water when time matters

Built for Real Farm Work

This coupling is perfect for connecting portable irrigation systems, filling water tanks, or setting up temporary water lines for livestock. The female coupler side accepts any matching male cam lock fitting, while the 3-inch female NPT end screws onto standard threaded pipes, pumps, or tank outlets. Whether you’re running a big irrigation pump or just need to connect hose sections quickly, this adapter bridges different connection types without fuss.

Made to Last

Farm water systems take abuse—UV exposure, temperature swings, and the occasional bump from equipment. This polypropylene coupler handles it all while staying flexible enough to make connections easy even in cold weather. The durable construction means you won’t be replacing it every season like cheaper alternatives.

Good to Know

Make sure your NPT threads are clean and use pipe thread sealant for the best seal on the threaded connection. The cam lock side seals with its built-in gasket, so no additional sealant needed there. Keep the gasket clean—a little dirt can cause big leaks when you’re moving hundreds of gallons.
