Universal 1/8" NPT Plug Fitting

If you're chasing down leaks or buttoning up an open port on a fuel system, oil rail, or sensor block, having the right plug makes all the difference. The Fleece 1/8" NPT O-Ring Plug is a simple but smart solution designed to seal things up cleanly and reliably. Unlike basic threaded plugs that rely solely on thread engagement, this fitting features an integrated face-seal O-ring, giving you a much tighter and more secure seal, especially important when you're dealing with fuel or fluid under pressure. It’s machined from stainless steel, so it’ll hold up to corrosion, temperature swings, and repeated removal without rounding off or seizing in place. The internal Allen head keeps the outside profile clean and flush, making it ideal for tight spaces or for anyone who prefers a low-profile, professional finish.
