Adapter Kit - Oil Press 1/8-27 NPT to Metric

The EQUUS Adapter Kit – Oil Press 1/8-27 NPT to Metric is a precision straight-thread fitting solution designed to bridge NPT (National Pipe Thread) and metric hydraulic systems. This adapter kit converts a 1/8-inch NPT female connection to three metric male options: 10 mm × 1.00, 12 mm × 1.50, and 14 mm × 1.50 threads, plus a 1/4-inch NPT male outlet, providing maximum flexibility across multiple oil pressure monitoring applications in automotive and equipment diagnostics.

Manufactured in brass with a natural finish, this oil pressure fitting kit offers reliable corrosion resistance and durability in high-temperature engine bay environments. The straight-thread design eliminates complex angular offsets, simplifying installation while maintaining a secure seal at critical pressure points. At 0.16 lbs and compact dimensions (4.85 × 0.7 × 5.05 inches), the adapter kit integrates seamlessly into tight engine compartments without adding bulk or weight. The multiple metric thread options allow technicians and enthusiasts to match legacy American-spec and modern metric pressure sender configurations on the same vehicle or across different diagnostic equipment.

This oil pressure adapter is essential for engine builders, shop technicians, and vehicle restorers working across mixed-specification powerplants. Whether transitioning from vintage domestic platforms with NPT sensors to modern metric-threaded pressure transducers, or swapping engine management systems that require different sender interfaces, this adapter kit eliminates the need to source individual fittings. The brass construction withstands the thermal cycling and pressure fluctuations inherent in oil pressure monitoring without degradation.

Oil pressure fitting compatibility varies significantly across platforms—American vehicles typically use NPT threads, while European and Japanese systems favor metric equivalents. Having a dedicated adapter kit on hand ensures you can instrument any engine with reliable pressure monitoring regardless of the original sensor thread specification, making this a valuable addition to any serious diagnostic or build toolkit.
