Description
When you’re plumbing hydraulic lines or adding fittings to your tractor’s hydraulic system, sometimes the threads just don’t match up. This straight adapter fitting solves that problem by connecting 3/8-18 male NPTF threads to 1/2-14 female NPTF threads, giving you the flexibility to make hydraulic connections work right the first time.
What You’re Getting
- Rated for 5000 PSI operating pressure—handles the high-pressure demands of modern hydraulic systems
- 1-1/8″ hex allows for easy installation and removal with standard wrenches
- Straight design keeps connections compact and reduces stress on hydraulic lines
- NPTF tapered threads create a reliable seal without needing additional thread sealant
Built for Real Farm Work
This adapter is perfect for hydraulic systems on tractors, loaders, and other farm equipment where you need to connect different sized hydraulic fittings. Whether you’re adding auxiliary hydraulics, repairing a damaged fitting, or adapting aftermarket implements to your tractor’s system, this fitting gives you the connection you need.
Made to Last
Built from quality steel with AgSmart engineering, this adapter is designed to handle the vibration, pressure, and temperature swings that come with hydraulic work on the farm. The NPTF threads seal tight and stay sealed, even when things get bumpy in the field.
Good to Know
NPTF threads are designed to seal on the threads themselves, so you typically don’t need pipe dope or thread sealant. Just hand-tighten until snug, then use a wrench to tighten an additional 1-2 turns. Don’t overtighten—you’ll strip the threads or crack the fitting.
