Description
When you’re building or servicing your sprayer boom and need to adapt a QuickJet cap to accept a 1/4″ threaded connection, this adapter cap gets you the connection you need. Whether you’re plumbing in a pressure gauge, check valve, or other accessory that uses quarter-inch threads, this handy piece makes it simple to integrate with your QuickJet setup.
What You’re Getting
- Durable Celcon construction that resists chemicals and field conditions
- QuickJet cap connection on one end, 1/4″ female NPT on the other
- Black color for easy identification and professional appearance
- Direct fit with TeeJet QuickJet systems—no modifications needed
Built for Real Farm Work
This adapter works with any QuickJet boom system where you need to add threaded accessories or instrumentation. You’ll find it useful when adding pressure monitoring equipment, check valves, or other components that require a 1/4″ male threaded connection. It’s especially handy on custom boom setups or when retrofitting existing spray equipment.
Made to Last
TeeJet builds this cap from Celcon, a tough engineering plastic that stands up to agricultural chemicals and UV exposure. It won’t crack or degrade like cheaper plastics, and the threads stay smooth for reliable connections season after season.
Good to Know
Installation is straightforward—just thread it into your QuickJet body like any other cap, then connect your 1/4″ threaded component. Make sure to use thread sealant or tape on the NPT threads for a leak-free connection. Keep a spare on hand since these small adapters have a way of walking off when you need them most.
