Built for Real Farm Work
This valve is designed for 3/8 inch outside diameter tubing and connects to NPTF threaded ports. It’s perfect for pneumatic systems on modern farm equipment like air seeders, grain handling systems, and implement control circuits. The push-to-connect fitting accepts standard pneumatic tubing without the need for clamps or ferrules.
Made to Last
John Guest has been making quality pneumatic fittings for decades, and this shut-off valve is built to their same high standards. The valve body and internal components are designed to handle the dust, moisture, and temperature extremes that come with farm use, keeping your pneumatic systems running when you need them most.
Good to Know
Installation is straightforward – just push the tubing into the fitting until it seats, and thread the valve into your NPTF port. To disconnect the tubing later, push in the release collar while pulling the tube out. Make sure to depressurize the system before disconnecting any fittings for safety.
