Description
When you’re working with pneumatic or fluid systems on farm equipment, getting the right connection between different sized lines can make or break your setup. This tube-to-hose stem adapter bridges that gap, letting you connect 1/2-inch rigid tubing to 3/8-inch flexible hose without leaks or pressure drops that’ll slow down your work.
What You’re Getting
- Secure connection that handles operating pressure without backing off or leaking
- John Guest quality construction built for agricultural and industrial applications
- Direct push-fit connection on the tube side—no threading or special tools needed
- Barbed stem design grips hose securely when properly clamped
- White polypropylene material resists corrosion and farm chemicals
Built for Real Farm Work
This fitting works in pneumatic systems for planters, sprayers, and air seeders where you need to connect different sized lines. It’s also handy for coolant systems, hydraulic return lines, and other fluid applications where you’re adapting between rigid tubing and flexible hose. The push-fit design makes connections quick and reliable, even in tight spaces or when you’re working with gloves on.
Made to Last
John Guest fittings are engineered to handle the vibration, temperature swings, and chemical exposure that come with farm use. The polypropylene construction won’t corrode like brass or steel can, and it maintains its grip on tubing even after years of use. These fittings are built to stay connected through harvest season, planting rushes, and everything in between.
Installation Notes
The tube side is a simple push-fit—just make sure your tubing end is cut square and clean. For the hose connection, slip the hose over the barbed stem and secure it with a proper hose clamp. A little soapy water makes sliding the hose on easier, and always double-check your clamp tightness before putting the system under pressure.
