TracTuff P75 Water Neck Flange
Our beautifully machined P75 (B18A, B18B, B20A, and B20Z) cylinder head 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 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.
