Description
Overview:
This tank cap washer is a flat, fuel‐resistant rubber seal that fits under the fuel tank cap on Honda small engines. It restores a tight, reliable seal to stop petrol leaks and vapour escape, helping to protect engine performance and reduce smells around stored equipment. Made from durable black elastomer designed for contact with fuel, it resists hardening and cracking over time. The washer is sized for a precise fit on popular Honda GX‐series engines used across construction, landscaping, and garden machinery. Ideal for routine maintenance on engines such as the GX120 and GX160, it is a simple, low‐cost part that helps keep the fuel system clean, safe, and efficient.
Key Features:
- Fuel‐resistant rubber construction for a long‐lasting seal
- Helps prevent fuel leaks and evaporation loss from the cap area
- Maintains correct tank pressurisation and smooth running
- Flat washer profile for stable seating under the cap
- Precise fitment for Honda GX‐series fuel caps, easy to install

Used on Honda petrol engines powering generators, water pumps, plate compactors, pressure washers, rotavators, tillers, and other small plant.
