TracTuff M20 to -12 Male Flare

The TracTuff M20 x 1.0 to -12 male flare is typically used to plumb an alternate main coolant inlet or outlet when going dry deck. 

The M20 x 1.0 thread is common on a number of cylinder heads... you can use this on the the right rear corner of the k series PRB/ PRC/ PPA/ and PPL cylinder heads, under the VTEC Spool Valve on VTEC B and H cylinder heads, under the distributer on SOHC D, SOHC F and non-VTEC B cylinder heads. Also offered in -6 and -10 male flare variants.

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.

Please DO NOT inquire about a CNC machined -16 male flare variant. I'm not interested... -16 does not make sense due to the mismatch in inside diameters. -16 has an ID that hovers around .8400” on average (different manufactures do different shit) whereas an M20 fitting with a sturdy wall has an ID that hovers around .5750”. The .265" (essentially a 1/4") restriction doesnt make any sense and you might aw sell go -12 which is a much closer match at an ID of around .6000"). So just change the fitting on the other end and save some money.

Alternatively, I can order a -16 hose end with a -12 nut that will screw on to this fitting OR a -12 hose end with a -16 nut for the other end... allowing a -12 hose (smarter of the two choices).
