Description
When you’re dealing with air lines on planters, sprayers, or any pneumatic system on your equipment, a broken or leaking connection can shut down your day fast. This John Guest union connector lets you join two pieces of 1/4-inch tubing together with a secure, leak-free connection that’ll handle the pressure and keep you moving through the field.
What You’re Getting
- Push-to-connect design that makes installation quick and foolproof – no threading or fumbling with fittings
- Secure grip on both sides that holds tubing tight even with vibration and movement
- Quality polypropylene construction that resists chemicals and won’t crack in temperature swings
- Sold in convenient packs of 10 so you’ve got spares when you need them
- Works with standard 1/4-inch O.D. polyethylene or nylon tubing
Built for Real Farm Work
These connectors are perfect for air seeders, pneumatic planters, and sprayer boom systems where you need reliable air flow. They’re also handy for shop air lines, hydraulic tank vents, and any other pneumatic application around the farm. The straight-through design maintains full flow without restrictions.
Made to Last
John Guest fittings are built to handle the demands of agricultural equipment. The internal gripping mechanism is designed to hold tight under pressure while the smooth bore keeps air flowing freely. They’ll stand up to dust, chemicals, and the temperature extremes you deal with from spring planting through harvest.
Installation Notes
Just push the tubing into each end until it seats completely – you’ll feel it click into place. To remove tubing later, push the release collar while pulling the tube out. Cut tubing square with a sharp knife for the best seal, and make sure there’s no debris on the tubing before connecting.
