2AN 1/8NPT Pipe Plug Clear 2/pkg

The 2AN 1/8NPT Pipe Plug Clear 2/pkg from REDHORSE PERFORMANCE delivers precision fluid system closure for high-performance automotive builds. These adapter plugs are essential for custom fuel systems, coolant circuits, and hydraulic setups where you need to cap off unused AN ports without sacrificing visual appeal or component integrity. Whether you're fabricating a custom fuel rail, modifying a turbo coolant loop, or building a bespoke brake circuit, quality pipe plugs prevent fluid leakage and contamination while maintaining system pressure integrity.

These plugs feature a 2AN connection on one end paired with a 1/8" NPT (National Pipe Thread) female port, allowing flexible configuration across multiple plumbing scenarios common in engine bay fabrication. The clear housing design lets you visually inspect for leakage and verify proper seating without disassembly—a critical advantage when diagnosing system anomalies under boost or during hot-start cycles. REDHORSE PERFORMANCE's aluminum construction ensures durability under vibration and thermal cycling while remaining lightweight, a priority in both street and competition applications. The package includes two plugs, giving you redundancy for multi-port systems or future modifications.

Mechanics and enthusiasts running LS swaps, turbo conversions, or custom coolant bypasses rely on these adapters to achieve clean, leak-free results without cobbling together mismatched fittings. Installation requires only a wrench and basic plumbing knowledge—hand-tight closure followed by a quarter turn with appropriate hex key prevents over-torque damage to the adapter interface. Compatibility spans any system using AN-series hose fittings paired with 1/8" NPT ports found on thermostats, remote filter mounts, sandwich adapters, and aftermarket manifolds. For builders prioritizing reliability and maintainability, these pipe plugs represent a proven, no-compromise solution.
