Description
When you’re building a custom cooling system, fuel line setup, or hydraulic circuit, you need fittings that seal reliably without unnecessary bulk. The Fragola 3/8 MPT Hex Pipe Plug delivers a clean, leak-free termination point with a compact hex head design that’s easy to access and torque down. This is essential for any race-ready or high-performance engine bay where space and reliability are non-negotiable.
Fragola’s blue anodized aluminum construction resists corrosion while keeping weight minimal—a smart choice whether you’re running a street machine or hitting the track. The hex head allows you to install or remove this plug without specialized tools, making system adjustments and maintenance straightforward.
