Uxcell 18mm Compressor Oil Fill Plug – Male Thread, 2-Pack

Got a compressor that's leaking oil or missing a fill cap?

These little guys might be what you need.

It's a 2-pack of 18mm oil fill plugs from Uxcell.

They're male thread, wire-type plugs—basically the kind you screw into the compressor crankcase to keep the oil where it belongs.

They're brand new, generic spare parts, but they get the job done.

Just a heads-up for California folks: there's a Prop 65 warning for cancer and reproductive harm, so wash your hands after handling.

But yeah, if you've lost a plug or yours is stripped, this 2-pack gives you a spare.

Simple, cheap, and effective.
