Description

Whether you need to isolate a section for maintenance or control air flow to pneumatic cylinders and actuators, this John Guest shut-off valve gives you the dependable operation you need when you’re in the middle of planting or spraying season.
What You’re Getting
- Quarter-turn operation for quick on/off control when time matters
- Durable construction that stands up to farm dust, moisture, and temperature swings
- 3/8 inch tube connection for common agricultural pneumatic lines
- 1/4 inch NPTF threaded port for secure connections to manifolds and gauges

Built for Real Farm Work
This valve is perfect for controlling air flow in pneumatic seed meters, row shut-offs, and other precision ag systems where you need to start and stop air flow quickly. It’s also handy for isolating sections of your pneumatic system when you need to service a meter or replace a line without shutting down the whole operation.
Made to Last
John Guest valves are built for industrial and agricultural use, not hobby applications. The materials and seals are designed to handle the pressure cycles and environmental conditions you’ll find on working farms, from spring planting through fall harvest.
Installation Notes
The 3/8 tube connection works with standard pneumatic tubing used in most ag applications. Just push the tube in until it seats—no tools needed. The 1/4 NPTF thread gives you a secure, leak-free connection to your manifold or gauge. A little thread sealant on the NPTF connection ensures it stays tight through vibration and temperature changes.
