PLUG - SAUCER TYPE 1-3/8 (Nissan NI00933-33500)

A damaged saucer-type plug can cause fluid leaks or pressure loss in a sealed system. This aftermarket replacement part references Nissan part number NI00933-33500. The plug is a saucer type with a 1-3/8 inch dimension, designed to seal an opening against fluid or gas escape. Its plain mechanical function is to block a port or hole when threaded or pressed into place. A common failure consequence is gradual seepage that leads to system inefficiency or contamination. During routine service, a worn plug may not hold pressure, resulting in operational delays. Verify the serial number or application, then call (562) 693-7748.
