  • TracTuff PR3 Water Neck Flange


    Our beautifully machined B18C5/ B16 flange is designed and machined with a 3D tapered entry port for a seamless transition to your choice of hose connection. The flange is threaded for a -16 ORB fitting but also has a generous o-ring seat that doubles as a weldable socket for custom jobs. The backside of the flange has an o-ring grove for a positive seal without the hassle of Hondabond. 

    NOTE: When using the OEM rubber or silicone replacement style upper radiator hose, I recommend emailing me and asking for a tube to be welded to the neck to recreate the outlet position. The flange includes two stainless M6 socket head bolts and an o-ring.
