Description
Overview:
The Seal Washer for Yanmar 3TNA72L Engine is a genuine Yanmar component designed to create a tight, leak-resistant joint at critical sealing points in diesel engines. Manufactured from copper for dependable crush-seal performance, it conforms to the mating surfaces as fasteners are tightened, helping to prevent fluid weeps and pressure loss. This washer is commonly used on fuel, oil, or coolant unions in Yanmar industrial engines found in compact plant, generators, agricultural equipment, and turf machinery. Supplied under OEM part number 22190-220002, it suits engines such as the 3TNA72L and 2TNV66-DMC, supporting reliable operation, easier maintenance, and reduced downtime. A fresh washer should be fitted whenever a sealed joint is disturbed to maintain factory-standard integrity and performance.
Key Features:
- Genuine Yanmar OEM part (22190-220002) for assured compatibility and fit
- Copper crush-washer construction provides a reliable seal under heat and vibration
- Helps prevent leaks at banjo bolts and other flanged or face-sealed joints
- Maintains fluid pressure and system efficiency in fuel, oil, and coolant circuits
- Corrosion-resistant material supports long service life in harsh environments
- Consistent quality control from Yanmar reduces the risk of rework
- Simple to install during routine servicing or component replacement
- Ideal to use as a single-use replacement whenever a joint is opened
Typical Applications:
Used when refitting fuel lines, injector pipes, banjo bolts, oil feed/return lines, and coolant unions on Yanmar diesel engines. Common during servicing, pump or hose replacement, and leak rectification. Fit a new washer to restore proper sealing after any disassembly and torque fasteners to the manufacturer's specification to ensure a uniform crush and leak-free joint.
