Title:
O RING(SFI93-046)(SGM9 (KU-0481600140)
Description:
The Kubota O-ring (SFI93-046 / SGM93-016) – KU-0481600140 is a precision-moulded sealing component designed to maintain leak-proof performance in critical hydraulic, transmission, and fluid system assemblies. It forms a tight, reliable seal between mating surfaces, preventing the escape of oil, fuel, or hydraulic fluid while also blocking contaminants from entering the system.
Because Kubota machinery operates under high pressure and temperature fluctuations, this O-ring uses durable, high-quality elastomer material that resists deformation, cracking, and chemical degradation. As a result, it maintains elasticity and sealing integrity even in demanding working environments such as construction, agriculture, and landscaping.
Moreover, this O-ring plays a vital role in protecting internal components such as pumps, valves, and hydraulic lines. By maintaining proper sealing, it ensures consistent system pressure, improves efficiency, and prevents costly downtime caused by leaks or contamination. Replacing worn or damaged seals with the genuine KU-0481600140 restores optimal performance and extends the lifespan of surrounding components.
Additionally, its OEM specification guarantees precise fitment, making installation straightforward while ensuring correct compression and sealing performance.
Model Fitment:
The KU-0481600140 O-ring is widely used across Kubota hydraulic, engine, and transmission systems, making it compatible with a broad range of equipment categories.
