XCMG Spare Parts Y RING Y 85X100X9 803429347
Description
This genuine XCMG Y ring, part number 803429347, is a direct replacement for the seal you would find in original equipment. It is not a universal aftermarket part; it is made to the precise specifications required for your machinery .
We measure this Y-ring at 85mm internally, with an outer diameter of 100mm and a 9mm cross-section. Getting these dimensions right is critical for proper compression and sealing, so always verify your old part matches these numbers before installation.
It is molded from a specially formulated polyurethane compound. This material gives the seal its flexibility for easy installation while maintaining the stiffness needed to resist extrusion under high pressure in the cylinder.
The "Y" profile is designed to provide a positive seal at both low and high pressures. As hydraulic pressure increases, the lips of the seal deform just enough to hug the metal surfaces tighter, preventing bypass leaks.
This is a stock item ready to ship. Whether you are rebuilding a cylinder or performing preventative maintenance, using the genuine XCMG component ensures the job is done right the first time.
