Keywords: 11103386, Piston Seal, Hydraulic Piston Oil Seal, Excavator Seal Ring, Excavator Hydraulic Spare Parts, Construction Machinery Sealing Parts

Product Overview

This piston seal 11103386 is a core hydraulic sealing component for heavy‑duty construction machinery hydraulic cylinders. It is installed on the piston of hydraulic cylinder to prevent high‑pressure hydraulic oil leakage across the piston, maintain stable internal pressure of hydraulic cylinder and guarantee normal stretching and retracting movement of boom, arm and bucket cylinder. This high‑quality aftermarket replacement seal effectively solves common faults including hydraulic oil leakage, weak cylinder thrust, slow action and pressure loss caused by aging, cracking or abrasion of old sealing rings. It is an essential spare‑part for hydraulic cylinder overhaul and hydraulic system maintenance.

Detailed Specifications

Key Features & Advantages

• Exact OEM‑Matching Installation Dimension Precision‑cut size, perfect fit for the corresponding piston groove, easy installation without modification.
