LS Engine Swap M16 x 1.5 Adapter to 1/8 NPT

The ICT BILLET LS Engine Swap M16 x 1.5 Adapter to 1/8 NPT is a precision-engineered fitting designed for LS engine swap projects requiring reliable fluid and sensor line connections. This straight adapter bridges the M16 x 1.5 metric thread on LS engine blocks to standard 1/8 inch NPT (National Pipe Thread) female ports, making it essential for custom cooling, oil pressure, and auxiliary system plumbing during engine conversions.

Manufactured from aluminum in a natural finish, this adapter combines lightweight construction with corrosion-resistant properties suitable for engine bay environments. The M16 x 1.5 male thread accommodates the metric port on LS-series engines, while the 1/8 NPT female thread accepts industry-standard aftermarket fittings and sensors. The straight configuration eliminates angled flow paths, reducing turbulence and pressure loss in pressure-sensitive applications like oil monitoring systems and coolant bypass circuits.

LS engine swaps into first-generation F-body Camaros, third-generation Fbodies, C4 Corvettes, and custom chassis demand meticulous attention to port compatibility. This adapter solves the mismatch between metric LS engine ports and the predominantly NPT-threaded aftermarket ecosystem. Whether you're plumbing an oil cooler, integrating a water temperature sensor, or routing auxiliary lines, this M16 x 1.5 to 1/8 NPT fitting ensures secure, leak-free connections that withstand engine bay heat and pressure cycles.

ICT BILLET specializes in aluminum billet fittings and adapters engineered specifically for LS swaps, and this adapter reflects that focus on precision thread matching and durability. At 0.06 lbs, it adds negligible weight to your engine bay while delivering the adapter functionality required to integrate LS platforms into non-factory environments.
