Description
When you’re setting up a spray system or irrigation line and need to connect different sized pipes, this little poly coupling does the job without fuss. It steps down from a 1/2 inch line to a 1/4 inch outlet, making it perfect for those spots where you need to branch off a smaller line or connect to different sized equipment. No hunting around for adapters or stacking multiple fittings—this one piece handles the size change cleanly.
What You’re Getting
- Direct size reduction from 1/2 inch male threads to 1/4 inch female threads in one fitting
- Lightweight poly construction that won’t rust or corrode like metal fittings
- Standard NPT threads that mate up with most agricultural and irrigation equipment
- Chemical resistant material that handles fertilizers and spray solutions without breaking down
Built for Real Farm Work
This coupling works great in spray tank setups, irrigation systems, and anywhere you need to step down pipe sizes on chemical-resistant lines. Whether you’re plumbing a boom sprayer, setting up a small irrigation system, or connecting spray equipment with different thread sizes, it handles the transition smoothly. The poly material makes it ideal for agricultural chemicals that would eat up brass or steel fittings over time.
Made to Last
AgSmart builds their poly fittings to handle farm conditions without the weight and corrosion problems of metal. The material stays flexible in cold weather and won’t crack from chemical exposure or UV rays. It’s the same tough poly construction used throughout the agricultural spray industry.
Good to Know
Thread the 1/2 inch male end into your larger line first, then connect your 1/4 inch equipment to the female end. Use quality thread sealant or tape for leak-free connections. The poly material threads easier than metal, so don’t over-tighten—snug plus a quarter turn usually does it.
