Description
When you’re dealing with pneumatic systems on your equipment, having a reliable way to shut off air flow at a moment’s notice can save you time and keep you safe. This John Guest shut-off valve gives you that control right where you need it, whether you’re working on air-powered tools or pneumatic controls on your tractor.
Key Features
- Quarter-turn operation lets you shut off air flow quickly when you need to make repairs
- 1/4 inch NPTF threading on both ends makes installation straightforward with standard fittings
- Compact design fits in tight spaces where larger valves won’t work
- John Guest quality means it’ll hold up to the dirt and vibration that comes with farm work
Built for Real Farm Work
This valve handles the air systems you’ll find on tractors and implements across all brands. Whether it’s controlling pneumatic seeders, air-powered cleaners, or cab air systems, this little valve does the job without taking up much room. The quarter-inch size is perfect for smaller air lines that need positive shut-off control.
Made to Last
John Guest has been making pneumatic fittings for decades, and they know what works in tough environments. This valve uses materials that resist corrosion and seals that stay flexible through temperature changes. You won’t be replacing it every season like some cheaper alternatives.
Good to Know
The NPTF threads create a tight seal without needing thread tape, though a little pipe dope never hurts. Make sure to shut off your air compressor before installation, and test the valve with low pressure first to make sure everything’s sealed properly. The quarter-turn handle gives you a clear visual of whether the valve is open or closed.
