TracTuff M20 to -12 Male Flare
The TracTuff M20 to -12 Male Flare is the first M20 fitting to be CNC machined rather than 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. You can use this option to plumb coolant to anything that might need it.
NOTE: The M20 x 1.0 thread does not seal on its own; 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.
