This clean multi-purpose billet CNC fitting is 16mm x 1.5 with a 1/8” NPT hole. This fitting can be used on many of the Sportbike engines for oil passage or water jacket access. Pressure and temperature senders from all major gauge manufacturers thread right in. The 16mm side of the fitting is designed to use the crush washer that is currently on the engine. The hex portion of the fitting is 19mm for easy installation and removal. Pictured is the fitting in use on the Suzuki Hayabusa for oil pressure, water temperature and oil feed to a turbo.
