Product Details
With this AutoMeter adapter, you get a brass fitting that converts a 1/8 inch NPT female port to a M12x1.5 male thread. This is commonly used when installing electric temperature or pressure gauges, especially in GM LS engine cylinder heads where that M12x1.5 thread is often found. It’s a straightforward piece that helps you connect your gauge sender to the engine properly.
