TracTuff M20 to AN Adapter

M20 to AN adapters are made from brand new Genuine Honda joints that have been machined and welded.

The M20 joint is typically used on the right rear corner of the k series PRB/ PRC/ PPA/ and PPL cylinder heads to route coolant to the heater core assembly. Use this option to plumb coolant to anything that might need it.

Please consider the k series thermostat port adapter or the k series water passage adapter to complete the coolant loop. Both of these products would create the suction needed to be a return.

NOTE: The OEM zinc finish and the original thread paste shown will not survive the welding process and will look different from the product photographed.

The product is machined and welded as orders are placed... so allow for a few days for the order to ship. All sales are final on this item. 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 is my last recommendation. All must be applied thoroughly into the threads.

Understand that not all "AN" hose is the same and there will be variances from manufacture to manufacture as well as in different types of hose from the same manufacture.

EXAMPLE: XRP Push-lock hose has an ID of 3/8" for -6, 1/2" for -8, 5/8" for -10, 3/4" for -12 but the XRP CPE or XR-31 hose has an ID of 11/32" for -6, 7/16" for -8, 9/16" for -10, 11/16" for -12.
