Description
When you’re working on your sprayer or irrigation setup, there’s nothing more frustrating than a fitting that won’t seal properly or can’t handle the chemicals you’re running through the system. This polypropylene pipe cap gives you a reliable way to cap off lines and test connections without worrying about leaks or chemical damage that can eat up your day and your budget.
What You’re Getting
- Heavy-duty polypropylene construction that resists fertilizers, herbicides, and most agricultural chemicals
- 150 PSI pressure rating handles everything from gravity flow to high-pressure sprayer systems
- 1/2 inch FNPT threads for a secure connection to male pipe threads
- Schedule 80 wall thickness provides extra durability for farm use
- Precision molded with fiberglass reinforcement for dimensional stability
Built for Real Farm Work
This fitting works in hydraulic systems on tractors and implements, irrigation lines for crop watering, sprayer plumbing for herbicides and fertilizers, and water systems around the farm. Whether you’re capping off unused ports on your tank, sealing test points on your boom, or temporarily closing lines during maintenance, this cap handles the job.
Made to Last
Farm chemicals can be tough on equipment, but polypropylene stands up to the punishment. This cap won’t crack, corrode, or break down when exposed to fertilizers, pesticides, or UV rays from working in the sun all day. The fiberglass reinforcement keeps the threads from stripping even after repeated use.
Good to Know
The threads are standard 1/2 inch FNPT, so this cap screws right onto any matching male fitting. When you’re pressure testing your system, this cap can handle up to 150 PSI safely. Keep a few extras in your toolbox—they’re handy for isolating sections of your plumbing when troubleshooting problems.
