Metric adapter fitting designed to convert a metric M16 x 1.5 male threaded port to a standard 1/8 inch NPTF female connection. This fitting is commonly used for oil pressure sensor or gauge line installation on GM LS engines, connecting to the port located on the top of the block behind the intake manifold.

Constructed from solid brass for strength, corrosion resistance, and reliable sealing, this adapter is well suited for street, performance, and custom applications where metric-to-NPT adaptation is required.
