This special machined brass Tee fitting has a male M16 (16x1.5mm) fitting at one end, a female M16 port at the other, and a female 1/8 NPT port in the side. It makes it easy to connect an aftermarket oil pressure gauge or warning light to an OEM 16mm port port on your engine while retaining the stock sender.
Simply thread the male M16 end into the original port, then install the original sender into the female M16 end. You can install your aftermarket sender in the female NPT port on the side, or for best results, use a 3AN hose and adapters (sold separately) to mount your aftermarket sender remotely.
Overall length (including male threads) 2 1/2" (64mm). For use in fuel and oil systems only (not for brakes). Sold individually.
