The Peterson Fluid Systems straight oil pressure fitting converts an engine's 1/8" NPT port to a -4AN outlet to bring the gauge line to a more convenient location. Measuring 2.25 inches overall, it simplifies routing for pressure monitoring. Use it where a straight -4AN connection is preferred from a 1/8 NPT engine port for accessible gauge placement.
