END CAP CYL (Hyster HY1591667)

A worn end cap on a cylinder can allow fluid leakage, reducing system pressure and causing sluggish operation. The end cap seals the cylinder barrel, retaining the piston and fluid within the assembly. Hyster catalog reference HY1591667 identifies this aftermarket replacement part. During a cylinder rebuild, technicians often replace the end cap to restore proper sealing. Verify the serial number or application, then call (562) 693-7748. A cracked end cap may lead to contamination entering the cylinder, accelerating internal wear. Keeping the end cap in sound condition helps maintain consistent cylinder performance.
