Description
When you’re working on hydraulic systems, nothing’s more frustrating than a fitting that won’t seal properly. Whether you’re temporarily capping off a line during maintenance or need to block an unused port, this OFS hydraulic plug gives you a clean, leak-free seal that handles the high pressures your equipment demands. It’s one of those simple parts that saves you time and keeps hydraulic fluid where it belongs – in the system, not on the shop floor.
What You’re Getting
- 1-1/2 inch male OFS (O-Ring Face Seal) design for reliable, leak-free connections
- Heavy-duty steel construction that handles high hydraulic pressures without cracking
- Precision threads that engage smoothly and seal tight every time
- O-ring face seal design eliminates the guesswork of proper tightening
- Direct replacement for factory OFS fittings – no adapters needed
Built for Real Farm Work
This plug works in hydraulic systems across all types of farm equipment – from tractors and combines to balers and sprayers. The OFS design is commonly found on newer hydraulic systems where reliable sealing is critical. Whether you’re servicing a loader valve block, capping off unused remotes, or doing winter maintenance on hydraulic cylinders, this plug handles the job.
Made to Last
Steel construction means this plug won’t crack under pressure like cheaper alternatives. The O-ring face seal design creates a positive seal that doesn’t rely on thread compound or excessive tightening. Once properly installed, it stays sealed through pressure cycles and temperature changes that would cause other fittings to weep.
Good to Know
The O-ring face seal design means you tighten until the O-ring contacts the mating surface, then turn just enough to compress the O-ring – no more guessing about proper torque. Always inspect the O-ring before installation and replace if it’s nicked or hardened. Keep a few extra O-rings on hand since they’re the wear item in this type of fitting.
