XCMG Spare Parts O RING 125×3.1 803195337

This is a genuine replacement O-ring, precisely manufactured to the original factory specification for XCMG heavy machinery. It serves as a critical static seal in hydraulic systems, ensuring fluid ports and component junctions remain leak-free under high pressure. Using a non-genuine ring here often leads to early system failure.

The dimensions are exactly 125 millimeters for the inner diameter and 3.1 millimeters for the cross-section. It is made from a durable nitrile rubber compound (NBR), chosen for its excellent resistance to hydraulic oils, greases, and high operating temperatures. This specific material composition provides the necessary elasticity and long-term reliability.

It is the direct OEM replacement for part number 803195337. We recommend always verifying your existing part's markings or consulting your equipment's parts manual to confirm fitment before installation. This ring is typically used in applications like pump joints, valve block interfaces, and cylinder end caps.

When installing, ensure the gland and groove are perfectly clean and free of any old seal material or debris. A light coating of clean hydraulic oil on the ring will prevent it from rolling or pinching during assembly. Proper seating is essential for the ring to form a perfect seal once the components are torqued down.

This O-ring is stocked as a critical service part, allowing for quick turnaround on repairs to minimize your machine's downtime. It reflects the quality control standards of XCMG components, providing a reliable seal to maintain system pressure and prevent fluid loss in demanding operational conditions.
