Description
Whether you’re building a custom spray rig or repairing a busted irrigation line, having the right fittings makes all the difference. This 4-inch poly nipple gives you a reliable way to connect two female threaded components in your plumbing system. It’s the kind of fitting that comes in handy when you need to extend a run or bridge a gap between valves, tanks, or other equipment.
What You’re Getting
- Durable polypropylene construction that won’t corrode like metal fittings
- Male NPT threads on both ends for secure connections to female fittings
- 4-inch length gives you the reach you need for proper spacing
- Chemical resistant material handles fertilizers, herbicides, and other ag chemicals
- Lightweight design that’s easy to handle and install
Built for Real Farm Work
This fitting is right at home in sprayer systems, irrigation setups, and chemical handling applications around the farm. The 1-1/2 inch size handles good flow rates for field sprayers and larger irrigation systems. It’s also handy for custom tank builds and equipment modifications where you need to connect components that are spaced apart.
Made to Last
Farm chemicals and UV exposure can eat up cheaper fittings in no time, but this polypropylene construction holds up to the harsh conditions you’ll throw at it. It won’t rust, corrode, or crack like metal or cheaper plastic alternatives, and it maintains its seal integrity season after season.
Installation Notes
Thread this fitting hand-tight plus about a quarter turn with a wrench—don’t over-tighten poly fittings or you’ll crack them. Use thread sealant or Teflon tape on the threads for a leak-proof connection. The 4-inch length gives you some flexibility in positioning your connections just where you need them.
