Description
When you’re setting up pneumatic controls on your equipment or need to connect air lines in tight spaces, having the right coupling makes all the difference. This solid brass hex coupling gives you a reliable connection between 3/8 NPT threaded air fittings while letting you tighten it properly with a wrench—no more rounded fittings from trying to hand-tighten in cramped spots.
What You’re Getting
- Solid brass construction that won’t corrode or crack under pressure
- Female threads on both ends for connecting male NPT fittings
- Hex design lets you use a wrench for proper installation and removal
- 3/8 NPT threading fits standard pneumatic system components
- Compact design works well in tight installation spaces
Built for Real Farm Work
This coupling is perfect for connecting pneumatic cylinders, valves, and gauges on your tractors and implements. Whether you’re plumbing air controls on a planter, hooking up pneumatic seed meters, or connecting pressure lines for air-actuated equipment, this fitting gives you a secure connection that won’t leak when you need consistent air pressure most.
Made to Last
Brass doesn’t rust like steel fittings, and it handles the vibration and temperature changes that come with farm equipment better than plastic alternatives. The hex shape distributes wrench pressure evenly, so you can get a good seal without over-torquing and damaging threads.
Installation Notes
Use pipe thread compound or Teflon tape on the male threads going into this coupling—never on the coupling’s female threads. Don’t over-tighten; brass is softer than steel and threads can strip if you get aggressive with the wrench. A good seal should happen with just hand-tight plus about half a turn with your wrench.
