This tube-to-hose stem fitting gives you a clean, secure connection that won’t leak under pressure, so you can get back to work without worrying about fluid loss or contamination getting into your system.
What You’re Getting
- Connects 1/2 inch outside diameter tubing to standard rubber or hydraulic hose

- John Guest quality construction designed for reliable service in demanding conditions
- Sold in quantity of 10 so you’ll have spares when you need them

Where This Part Shines
These adapters work great on hydraulic systems for loaders, backhoes, and other equipment where you need to transition from metal tubing to flexible hose. They’re also handy for pneumatic systems on air seeders, spray equipment, and other machinery that uses compressed air. The 1/2 inch size fits common hydraulic and pneumatic applications on most farm and construction equipment.
Made to Last
John Guest fittings are known for holding up in tough conditions, and these tube stems are no exception. The material resists cracking from temperature changes and won’t corrode like some metal fittings can. They’re designed to handle the pressure and vibration that comes with mobile equipment use.
Installation Notes
Push the tubing into the fitting until it bottoms out, then slide your hose over the barbed stem. For high-pressure applications or where vibration is a concern, add a hose clamp over the barbed connection. Keep a few extras in your toolbox – you’ll be surprised how often these come in handy for quick repairs.
