Description
Overview:
This seal washer is a small but vital service part for Robin/Subaru compact petrol engines, purpose-made for the EC03 and EC04 series. It is a flat, ring-shaped metal washer designed to create a tight, leak-resistant seal under a fastener or fitting. By compressing evenly under torque, it helps prevent seepage at joints and threaded connections, supporting smooth and reliable engine operation. Built from durable metal for repeated heat cycles and vibration, it is suitable for routine maintenance and repairs where a sealing washer is specified on the engine. Referenced to OEM No. 690-45005-00, it offers a direct, like-for-like replacement to restore sealing performance with minimal downtime and consistent results for both workshop and site use.
Key Features:
- Direct replacement referenced to OEM No. 690-45005-00 for assured fit on EC03 and EC04 engines
- Flat metal sealing washer for dependable leak control at joints and threaded fittings
- Robust construction resists heat, vibration, and common workshop fluids
- Helps maintain compression at the joint to support engine efficiency and reliability
- Straightforward to fit during routine servicing; install like-for-like and torque the joint correctly
- Suitable for use at drain plugs, banjo connections, covers, and other specified sealing points
- Consistent performance reduces the risk of rework caused by weeping seals
- Compact, low-cost component that protects more expensive engine parts by preventing leaks
Typical Applications:
Used wherever the EC03 or EC04 engine specifies a sealing washer, including oil drain plugs, carburettor banjo bolts, fuel line unions, and small cover fasteners. Ideal during oil changes, carburettor servicing, hose replacement, and general rebuilds. Suitable for repairs in workshops, on-site, or at home, helping keep engines clean, efficient, and ready for daily use.
