The Graco C-315 Washer, Crush, Alum, .312Id is a precision aluminum crush washer designed to create a tight, leak-resistant seal between metal components in high-pressure Graco fluid systems. It deforms under torque to fill microscopic gaps, ensuring reliable sealing performance.
It is commonly used in fluid pathways where vibration, pressure, or thermal expansion could otherwise cause leakage, making it a critical sealing element in industrial spray and pump assemblies.
This washer is typically installed in fluid connection points within Graco spray rigs, pump assemblies, and industrial dispensing systems where secure, pressure-tight sealing is required.
