TracTuff P72 Water Neck Flange


Our beautifully machined P72 (B18C1) cylinder head flange is designed and machined with a 3D tapered exit 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 against the cylinder head without the hassle of Hondabond. 

The flange includes two stainless M6 socket head bolts, an o-ring, and your choice of standard hose (1.25" OD) or -16 male flare port fitting.
