Product description
The T-pieces are made of aluminum. You screw these T-pieces into the engine block instead of the original oil pressure switch.
The screw thread on the back of the T-piece is the same as on the engine block, so you can screw back the original oil pressure switch.
In addition, the T-piece has a 2nd threaded hole (1/8 NPT) on the side to accommodate a sensor or pipeline for an oil pressure gauge.
Sensor connection: 1/8 NPT
