PRODUCT DETAILS
TracTuff M18 to -6 Male Flare Fitting
The TracTuff M18 to -6 Male Flare Fitting is a precision-engineered solution for enthusiasts looking to enhance the cooling and oil management systems of their Honda or Acura K Series engine or Honda S2000 (F20C/F22C). Designed to replicate the specifications of the original Honda coolant joint used on the S2000, this fitting allows you to easily route coolant from the block to an oil cooler or any other auxiliary component requiring water flow.
CNC machined from 6061-T6 aluminum for superior strength, corrosion resistance, and lightweight durability, the TracTuff M18 to -6 Male Flare Fitting delivers OEM-level precision with aftermarket versatility. It’s the perfect choice for K20, K24, and S2000 engine builds that were not originally equipped with an oil cooler but need a clean, reliable way to plumb one in. Whether you’re completing a custom coolant loop or upgrading to an OEM oil cooler, this fitting ensures consistent, leak-free performance.
For a complete coolant circuit, TracTuff recommends pairing this fitting with their K-Series Thermostat Housing Port Adapter or Water Pump Port Adapter for the low-side return. When installing, use Loctite 5452 for a fast-curing sealant or Loctite 561 if a 24-hour cure time is available—both ensure a secure, pressure-resistant seal.
