RELIEF KIT (CAT CT0354783)

A worn relief kit can cause system pressure to drop unexpectedly, leading to erratic operation or component damage. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT0354783. The relief kit functions as a pressure-limiting assembly that opens at a preset threshold to protect downstream components. A common failure consequence is that a stuck-closed relief valve may allow pressure to exceed safe limits, risking seal or housing rupture. During a pressure test, a technician might observe that the system fails to hold rated pressure due to a leaking relief kit. The item ships at approximately 0.033 pounds. Verify the serial number or application, then call (562) 693-7748.
