RING - SQUARE BACK UP (Bobcat BC73K14)

A damaged square back-up ring can allow seal extrusion under high pressure, leading to fluid leaks and system inefficiency. This aftermarket replacement part references Bobcat as the OE maker and cross-references part number BC73K14. The ring functions as a mechanical barrier that supports the primary seal in a gland or groove. Without a sound back-up ring, the seal may deform and fail prematurely during pressure spikes. Keeping this component in good condition helps maintain consistent sealing force in static or dynamic applications. The item ships at approximately 0.004 POUNDS. Verify the serial number or application, then call (562) 693-7748.

Part number variants: BC73K14, bc73k14
