Description
The Mishimoto -12AN Push Lock Fitting (MPN: MMFT-PL-1245) is a 45-degree, silver and black anodized aluminum fitting built for fabricators who need a fast, leak-free -12AN connection point. It pairs a 1 1/16 in – 12 UNF end with a -12AN push-lock end, letting you tie -12AN line into your system without the fuss of traditional AN fittings.
As part of the Mishimoto Fabrication lineup, this push lock fitting is designed to make custom plumbing simple. The -12AN push-lock port allows the fitting to assemble in minutes, while precision machining is engineered to provide a leak-free connection with -12AN line. Rated to a maximum fluid temperature of 248°F and a maximum fluid pressure of 5000 PSI, it’s built to handle demanding under-hood environments, and it’s suited for use with engine oil, coolant, fuel, and similar fluids. The corrosion-resistant anodized coating keeps the silver and black finish looking sharp while standing up to the elements, making it a practical and good-looking addition to any Mishimoto Fabrication build.
Vehicle Applications
This is a universal Mishimoto Fabrication component rather than a vehicle-specific part, so it isn’t tied to a particular make, model, or year. Instead, it’s intended for custom fabrication work such as building or modifying oil coolers, transmission coolers, catch cans, and other custom -12AN plumbing setups on your own project vehicle.
