1/8in Npt to M10x1 Adapter

The AutoMeter 1/8in NPT to M10x1 adapter is a precision brass fitting designed to connect oil pressure gauges and other instruments using different thread standards. This straight adapter bridges the gap between 1/8-inch NPT (National Pipe Thread) female ports and 10mm x 1.0 male metric threads, making it essential for gauge installations on engines and fuel systems where metric and imperial ports coexist.

Constructed from brass in natural finish, this adapter provides reliable corrosion resistance and durability in engine bay environments where temperature fluctuations and fluid exposure are common. The straight configuration eliminates bend radius concerns and simplifies installation in tight spaces. Both the 1/8-inch NPT and M10x1 threads are industry-standard sizes, ensuring compatibility with a wide range of gauge senders, pressure transducers, and diagnostic equipment. The compact 3.4 x 0.8 x 3.8-inch dimensions allow installation in confined areas where larger fittings would not fit.

This adapter is commonly used during engine swaps, gauge retrofits, and custom instrumentation builds where OEM and aftermarket pressure sending units operate on mismatched thread patterns. Whether upgrading from mechanical gauges to electronic sensors or integrating specialized monitoring equipment, this AutoMeter fitting ensures leak-free connections without modification to either the engine block port or the gauge sender itself.

NPT to metric adapter fittings are foundational components in engine instrumentation. AutoMeter's precision manufacturing ensures thread accuracy and seal integrity, critical factors in systems carrying pressurized oil or fuel. TacticalSurplusUSA stocks this individual adapter for builders and technicians who need verified OEM-equivalent parts without purchasing complete gauge kits.
