Gauge Adapter AN -4 Male x -4 Male x 1/8in NPT

The Gauge Adapter AN -4 Male x -4 Male x 1/8in NPT by ALLSTAR PERFORMANCE is an essential component for engine builders and performance technicians who require accurate monitoring of fuel pressure, oil pressure, or boost levels. This adapter connects AN-4 hard line plumbing to NPT-threaded gauge ports, simplifying installation and minimizing potential leak points in high-vibration environments.

Designed for reliability, this compact fitting allows for simultaneous gauge installation without disrupting fluid lines. The adapter features AN-4 male ports and a 1/8-inch NPT female port, ensuring compatibility with various monitoring systems. Its precision engineering helps maintain concentricity across all ports, reducing the risk of fitting failures under pressure.

Ideal for professional engine builders and performance shops, this adapter is suitable for use in fuel rail manifold blocks, oil cooler thermostatic sandwich plates, and transmission cooler junctions. Its design is particularly beneficial for turbocharged or supercharged applications, where accurate pressure readings are crucial for optimal engine performance.
