Overview:
The Sender Oil Pressure for Yanmar 4TNE84T Engine (MPN 121252-39450) is a genuine Yanmar OEM sensor designed to protect and optimise industrial diesel engines. This brass-bodied, metal sensor mounts via a threaded male fitting with a hex for easy tightening, and provides a stable electrical signal to your gauge or control unit.
