Description

When you’re working with hydraulic systems, keeping dirt and contamination out of open ports is just as important as the fittings themselves. This steel cap screws onto any 3/4 female OFS (1-3/16-12) port to seal it tight when hydraulic lines aren’t connected. Whether you’re doing seasonal maintenance or storing equipment, these caps keep your hydraulic system clean and ready for work.

What You’re Getting

Precision-threaded steel cap that creates a secure seal on OFS ports
Heavy-duty construction that won’t strip or crack under normal use
Perfect fit for 1-3/16-12 thread pattern commonly found on farm equipment
Swivel design makes threading on and off quick and easy

Built for Real Farm Work

This cap fits hydraulic systems on tractors, implements, and other equipment that use the OFS (O-ring Face Seal) standard. You’ll find these threads on everything from loader valves to implement quick-couplers. The steel construction handles the temperature swings and rough handling that come with farm life.

Made to Last

Steel construction means this cap won’t crack like plastic versions when it gets cold, and it won’t strip out after a few uses. The threads are machined to match OFS standards, so you get a proper seal without having to overtighten and risk damage to your equipment.

Good to Know

Keep a few of these caps in your toolbox for hydraulic maintenance and storage. They’re especially handy when you’re disconnecting hydraulic lines for repairs or seasonal storage. Thread them on finger-tight plus a quarter turn – no need to reef on them with pliers.
