O-RING, 2.250 ID (Linde LI821)

LI821: A damaged retaining ring can allow a shaft or bore component to shift out of position during operation. The catalog reference for this aftermarket replacement part is Linde LI821. This O-ring type retaining ring has a 2.250 inch inside diameter and functions as a mechanical stop or seal within a groove. If the ring fails, the retained part may dislodge, causing sudden loss of assembly integrity. During a routine disassembly, a technician may find the ring deformed or cracked from repeated stress cycles. Keeping the ring in sound condition helps maintain consistent axial location of the installed component. Verify the serial number or application, then call (562) 693-7748.
