Description
When you’re running a sprayer with diaphragm check valves, this little brass end cap might seem like a small part—but it’s what keeps everything sealed tight and working properly. If your Chemsaver check valve is leaking or not holding pressure like it should, there’s a good chance this end cap assembly needs replacing. It’s one of those wear items that takes a beating from chemicals and pressure cycles.
What You’re Getting
- Precision-machined brass construction that handles farm chemicals without corroding
- Perfect fit for 4664 series Chemsaver diaphragm check valve nozzle bodies
- Complete assembly ready to install—no hunting for additional pieces
- Maintains proper seal and pressure regulation in your check valve system
Built for Chemical Resistance
This end cap is specifically designed for Chemsaver diaphragm check valves, which are the workhorses of boom sprayer systems. These check valves prevent drip and ensure consistent spray patterns by maintaining proper pressure at each nozzle. You’ll find them on field sprayers, vineyard rigs, and other precision application equipment where chemical accuracy matters.
Made to Last
Brass is the right material for this job because it stands up to the harsh chemicals and constant pressure changes that would eat up other materials. The machined threads stay tight, and the brass won’t pit or corrode like cheaper alternatives might. This is genuine TeeJet quality—the same standard that comes on your sprayer from the factory.
Installation Notes
Make sure your system is depressurized before removing the old end cap. Clean the threads on the valve body to remove any chemical residue or debris. Thread the new cap on hand-tight, then snug it with a wrench—don’t overtighten or you might crack the valve body.
