TracTuff M18 to AN Adapter

$29.95

-6 now CNC machined from 6061-T6 aluminum. Updated picture coming soon.

Same thread size and pitch as the original Honda joint used on the S2000 F20C/F22C to route coolant from the block to the oil cooler assembly, and commonly used on K Series engines that were not originally equipped with an oil cooler, to direct water to an OEM oil cooler. Now available to plumb anything that you might need to get water to.

Please consider the k series thermostat port adapter or the k series water passage adapter to complete the coolant loop. Both of those products would be a low-side return.

NOTE: -6 are CNC machined and always in stock and ready to ship. Please allow 4-5 business days for the -10 to be squeezed into my schedule, made, and shipped.

Extremely low demand on the -10 AN variant means I will continue to make them the harder/ more expensive way. Please understand that OEM zinc finish and original thread paste shown in the gallery photo will not survive the welding process, and if left untreated, will rust.

All sales are final on -8 and -10 variants. You will want to plate or paint this fitting to keep it from rusting. I recommend Loctite 5452 as a fast-cure thread sealant or Loctite 561 if you have 24 hrs. to cure. Loctite 561 may be more readily available, but it is my last recommendation. All must be applied thoroughly into the threads.

-6 is equal to a metal tube with an OD of 3/8" (.3750")
-10 is equal to a metal tube with an OD of 5/8" (.6250")

Understand that not all "AN" hoses are the same, and there will be variances from manufacturer to manufacturer, as well as in different types of hose from the same manufacturer.

EXAMPLE: XRP Push loc hose has an ID of 3/8" for -6 and 5/8" for -10, but XRP CPE and XR-31 hose have an ID of 11/32" for -6 and 9/16" for -10.
