At Fukoku Bussan, we supply a wide range of products,
primarily rubber, as well as resin and metal components.
Here, we introduce products from five key categories we handle.
automotive
Since our founding, we have been handling anti-vibration rubber used in vehicles, and we continue to develop and supply products aimed at improving vibration performance and durability. Primarily for automotive applications, we offer rubber and resin components such as hoses and engine covers used around the engine, which support the performance of internal vehicle systems. Though not visible, these components play a crucial role in ensuring vehicle safety, comfort, and quietness. In recent years, we have also been working to optimize product specifications and meet new technical requirements in response to the advancement of EVs and the diversification of mobility.

CONNECTOR SEAL
AUTOMOTIVEIt is a rubber sealing component used to prevent water, moisture, dust, and other contaminants from entering the connection area of an electrical connector. Installed either inside or around the connector, it plays a crucial role in ensuring airtightness and waterproofing. Designed for durability even in harsh environments such as automobile engine compartments, it protects the vehicle's electrical system.
-
WIRE SEAL
AUTOMOTIVEA rubber component that seals the gap between electrical wires and connectors to protect the electrical system and ensure stable performance over the long term. In addition to waterproofing, it is also used for dust prevention, blocking foreign matter, securing wires, and reducing vibration. It is mainly made from flexible materials such as silicone rubber.
-
ANTI-VIBRATION RUBBER
AUTOMOTIVEPlays a key role in absorbing and reducing vibrations and noise from the engine and road surface, enhancing in-vehicle comfort. It also helps prevent wear and damage to components, contributing to improved vehicle durability. Widely used in applications such as strut mounts, engine mounts, and body mounts, it is an essential component for safe and comfortable driving.
-
HOSE
AUTOMOTIVEA component designed to efficiently and safely transport various liquids and gases—such as fuel, oil, and air—within a vehicle. For example, a fuel hose delivers fuel from the tank to the engine and injectors efficiently, while being made of specialized rubber or resin with excellent oil and weather resistance. It plays a crucial role in preventing fuel leaks and supporting stable operation.
-
RESIN COMPONENTS (INCLUDING DUST COVERS)
AUTOMOTIVEResin components are used across a wide range of applications—from interior and exterior parts to electrical components—due to their lightweight nature, cost efficiency, and high design flexibility. For example, dust covers are used to protect movable suspension parts from external contaminants such as dust, mud, water, and oil. By preventing the intrusion of foreign substances, they help reduce wear and corrosion of internal components, playing a vital role in maintaining safe and comfortable driving.
