Description
When you need to cap off a hydraulic port during maintenance or testing, a proper seal makes all the difference between a clean job and oil all over the shop floor. This 5/8 female OFS swivel cap threads on securely to seal hydraulic ports, keeping contaminants out while you work on other parts of the system. The swivel design means you don’t have to worry about perfect alignment – it rotates freely to thread on smoothly every time.
What You’re Getting
- Female 5/8 O-ring face seal threads for secure, leak-free connection
- Swivel design allows easy installation without perfect port alignment
- Heavy-duty steel construction handles hydraulic system pressures
- O-ring face seal provides positive sealing against contaminants and leaks
- AgSmart quality built for the demands of agricultural hydraulic systems
Built for Real Farm Work
This cap works on any hydraulic system using 5/8 OFS ports, which you’ll find on everything from loader valves to remote hydraulic outlets on modern tractors. Whether you’re troubleshooting a stubborn cylinder, pressure-testing a rebuilt valve, or just keeping dirt out of open ports during winter storage, this cap does the job right.
Made to Last
Steel construction stands up to the pressure and abuse of farm hydraulic systems. The O-ring face seal design creates a positive seal that won’t leak under pressure, and the swivel feature means less stress on threads during installation. Built to AgSmart’s standards for agricultural hydraulic components.
Good to Know
Make sure your threads are clean before installing – debris on hydraulic threads leads to leaks and damaged fittings. The swivel feature makes installation easier, but don’t overtighten. The O-ring does the sealing work, not thread torque. Keep a few of these caps in your toolbox for those times when you need to isolate part of a hydraulic system.
