When you’re doing hydraulic work on your tractor or implement, you need to cap off unused ports to keep contamination out and system pressure intact. This 3/4 inch OFS (O-ring Face Seal) plug does exactly that—seals things up tight so you can keep working without worrying about dirt, moisture, or hydraulic fluid leaking where it shouldn’t be.
What You’re Getting
- Steel construction that stands up to high pressure and temperature swings on the farm
- O-ring face seal design provides a reliable seal without thread sealant or tape
- 1-3/16-12 thread pattern that matches common hydraulic system specifications
- Prevents contamination from entering unused hydraulic ports during service or seasonal storage
Built for Real Farm Work
This plug fits hydraulic systems across a wide range of agricultural equipment—from loader valves and remote hydraulic outlets to implement connections on planters, mowers, and balers. If you’ve got hydraulic ports that aren’t being used or need temporary sealing during maintenance, this is the part that gets the job done.
Made to Last
Steel construction means this plug won’t crack or fail like plastic alternatives might. The O-ring face seal design creates a metal-to-rubber seal that stays tight even when hydraulic pressures spike or temperatures swing from summer heat to winter cold.
Good to Know
Installation is straightforward—just thread it in finger-tight, then use a wrench to snug it down. Don’t overtighten, as the O-ring does the sealing work. Keep a few of these plugs in your toolbox for field repairs or when you’re temporarily removing hydraulic lines for maintenance.
