M16-1.5 Adapter 1/4NPT Oil Pressure Sensor

The M16-1.5 Adapter 1/4NPT Oil Pressure Sensor from ICT BILLET is a precision-engineered fitting designed for engine instrumentation and monitoring systems. This straight adapter bridges the gap between metric M16 x 1.50 male threads and standard 1/4 inch NPT female ports, making it essential for technicians and engine builders who need reliable sensor integration on custom or modified engine blocks. Whether you're installing aftermarket oil pressure gauges, data acquisition systems, or performance monitoring equipment, this adapter ensures secure, leak-free connections in demanding automotive and marine applications.

Constructed from lightweight aluminum with a natural finish, the M16-1.5 Adapter 1/4NPT Oil Pressure Sensor combines durability with corrosion resistance suitable for engine bay environments. The straight design eliminates flow restriction and simplifies installation, while the precision-machined threads on both the 16 mm x 1.50 male and 1/4 inch NPT female ports guarantee proper seating and prevent leaks under operating pressure. At just 0.06 lbs, this compact fitting (3 x 1.1 x 4.3 inches) integrates seamlessly into tight engine compartments without adding unnecessary weight or bulk to your build.

Engine builders, performance tuners, and restoration specialists rely on this adapter when converting European metric engine blocks to North American standard sensor ports. It works with any oil pressure sensor, transducer, or gauge equipped with 1/4 NPT female threads, making it a versatile solution for LS swaps, vintage engine restorations, and racing applications. Installation is straightforward—thread the M16 x 1.50 male end directly into your engine block and connect your 1/4 NPT sensor or adapter to the female port. For applications requiring sealant, PTFE tape or thread-locking compound is recommended to ensure pressure integrity.
