Description

When you need to seal off a hydraulic line temporarily or permanently, this female cap with swivel does the job right. Whether you’re testing a system, removing an implement, or protecting an unused port from dirt and contamination, you need a fitting that seals tight and stays put. This steel cap handles farm conditions while giving you the flexibility of a swivel connection that won’t bind up.

What You’re Getting

Female 9/16-18 thread matches standard O-Ring Face Seal (OFS) ports
Steel construction that won’t crack or fail under pressure
Swivel design prevents binding and makes installation easier in tight spots
Precision threads ensure proper sealing without over-tightening
Compact design won’t interfere with nearby components or hoses

Built for Real Farm Work

This cap fits any hydraulic system using 9/16-18 OFS threads, which you’ll find on tractors, loaders, combines, and implements across many brands. Whether you’re capping off unused remotes, sealing test ports during maintenance, or protecting hydraulic connections during equipment storage, this fitting keeps your system clean and leak-free.

Made to Last

Steel construction stands up to impact, weather, and the vibration that comes with farm equipment. The swivel feature means you won’t cross-thread or damage ports when installing, and the precise machining ensures a reliable seal every time you use it.

Good to Know

Thread the cap on hand-tight first, then snug with a wrench—don’t over-tighten as this can damage the O-ring seal. Keep a few of these handy in your toolbox for quick hydraulic system isolation during troubleshooting or seasonal equipment storage.
