Description
When you’re plumbing hydraulics and need to connect different thread types, this adapter fitting gets the job done without fuss. It bridges the gap between a 3/4-16 Male ORB connection and a 3/8-18 Female NPSM swivel, letting you hook up components that wouldn’t normally mate together. Perfect for those times when you’re retrofitting equipment or need to adapt between different manufacturers’ fittings.
What You’re Getting
- Straight-through design keeps things simple and minimizes pressure drop
- Swivel feature on the NPSM side makes installation easier and reduces stress on connected lines
- Rated for 3500 PSI operating pressure—more than enough for most hydraulic systems
- 7/8 inch hex body gives you a good grip when tightening connections
- Steel construction handles the vibration and pressure cycles of farm equipment
Built for Real Farm Work
This fitting works great in hydraulic systems on tractors, combines, balers, and other farm machinery where you need to connect ORB (O-Ring Boss) ports to NPSM (National Pipe Straight Mechanical) threads. The swivel feature is especially handy when you’re working in tight spaces or need to route hoses at specific angles.
Made to Last
Farm hydraulics take a beating with constant pressure changes, dirt, and temperature swings. This steel adapter is built to handle those conditions without leaking or failing when you need it most.
Installation Notes
The ORB side uses an O-ring seal, so make sure it’s clean and properly seated before tightening. The NPSM side relies on thread seal, so use appropriate thread sealant or tape. Don’t over-tighten—snug plus a quarter turn is usually plenty once the O-ring seats properly.
