Fragola Performance Systems has been the American race-fitting standard since 1985 — AN fittings, braided hose, and adapters in nearly every imaginable size and finish. The choice of NHRA Pro Stock, NASCAR Cup, and championship pro-touring teams.
The Fragola Performance Systems 4 AN O-Ring Port Plug is designed for applications where space is limited and a flush fit is required. Featuring an Allen head (socket hex) design, this plug sits flush within the port, providing a clean, low-profile appearance. The integrated O-ring ensures a superior, leak-proof seal, making it ideal for high-pressure oil or fuel ports where traditional NPT plugs might fail.
This plug is perfect for closing off unused ports on fuel rails, oil filter blocks, or custom intake manifolds. Because it uses an O-ring seal, you don't need to worry about over-tightening or using excessive thread sealant, which can contaminate your fluid system. Fragola Performance Systems manufactures these plugs to the highest standards, ensuring they remain secure even under extreme heat and vibration. When you need a reliable, professional-grade solution for your engine plumbing, look no further than this high-quality port plug.
