Description
The Mishimoto Race-Ready Radiator Fitting, part number MMRFT-20ANV2, is a -20AN x 1-5/8-12 fitting engineered specifically to directly fit the Mishimoto Race-Ready Radiator V2. CNC-machined from 6061 aluminum, this fitting gives builders running custom coolant lines a secure, precise connection point on their aluminum radiator setup.
As part of Mishimoto’s Fabrication lineup, this radiator fitting helps fabricators and builders put together a sturdy, well-sealed coolant system for their performance radiator. Whether you’re plumbing custom -20AN coolant lines for a car radiator or finishing off a high performance radiator build, this fitting offers a repeatable, accurate fit thanks to its CNC-machined construction and included sealing O-ring. It’s one of several Race-Ready Radiator Fitting options Mishimoto offers, alongside -16AN and push-on styles, so builders can match fitting style to their specific coolant line setup across a range of performance radiators and aluminum rad builds.
Vehicle Applications
This fitting is not tied to a particular vehicle year, make, or model. Instead, it’s designed to install directly onto the Mishimoto Race-Ready Radiator V2, making it a purpose-built accessory for that specific radiator rather than a universal part. Before purchasing, confirm that your radiator has 1-5/8-12 threaded inlets and outlets, since this fitting is engineered exclusively for that thread pattern. If you’re not sure whether your radiator matches, Mishimoto’s customer service team can help you identify it.
