Description
When your TeeJet 145H1 valve starts acting up—whether it’s dripping, not sealing properly, or just doesn’t have the pressure control it used to—this repair kit gets you back to consistent spraying without having to replace the entire valve. It’s got all the wear parts that typically go bad after a season or two of hard use.
What You’re Getting
- Complete set of EPDM seals and gaskets that handle agricultural chemicals and temperature swings
- All the internal components that wear out over time from chemical exposure and pressure cycling
- Quality parts that match the original valve specifications for proper fit and performance
- Everything you need for a complete valve rebuild in one convenient kit
Built for Real Farm Work
The 145H1 valve is a workhorse in agricultural spray systems, whether you’re running it on a boom sprayer, spot spraying equipment, or tank mixing setups. This kit keeps that valve functioning like it should, maintaining consistent pressure and flow rates when you’re applying herbicides, fertilizers, or other liquid treatments across your operation.
Made to Last
The EPDM seals in this kit are specifically chosen for their chemical resistance and flexibility. They’ll hold up to the harsh chemicals you’re spraying and won’t get brittle or crack like cheaper rubber compounds. These are the same quality seals TeeJet uses in their factory rebuilds.
Installation Notes
Take your time disassembling the valve and lay the parts out in order—it makes reassembly much easier. Clean all the valve body surfaces thoroughly before installing the new seals. A thin coat of compatible lubricant on the seals helps with installation and initial operation.
