Fleetguard FS1212 Oil-Water Separator

Fleetguard FS1212 is a high-performance spin-on Oil-Water Separator engineered by Cummins Filtration, specialized in diesel fuel systems for commercial vehicles and engineering machinery. It integrates efficient impurity filtration and water separation functions, effectively removing free and emulsified water as well as solid particulates from fuel to protect key engine components like injectors and fuel pumps from corrosion and wear.

With a compact structural design, this separator features an outer diameter of 93.22mm and an overall height of 201.17mm, matching 1-14 UNS-2B threaded port. It perfectly adapts to limited mounting spaces of various equipment, ensuring easy installation and quick replacement, and is fully compatible with mainstream diesel engine models such as Cummins KTA19 and L10.

Compliant with SAE J1985 industry standards, FS1212 undergoes strict factory testing for stable performance under harsh working conditions. As a reliable original matching part, it is widely applied in trucks, excavators, power generation equipment and agricultural machinery, providing long-term protection for diesel engine fuel systems.

Advantages of  FS1212 Oil-Water Separator

• High-efficiency filtration and separation: It achieves 96% particulate filtration efficiency at 20μm precision and 90% separation efficiency for both free and emulsified water in fuel, thoroughly eliminating fuel system contamination risks and ensuring clean fuel delivery.

• Robust structural durability: Adopting high-strength metal canister and premium sealing gaskets, it resists pressure impact and vibration in complex working environments, with no leakage risk and long service life under rated working conditions.

• Universal compatibility & easy maintenance: Following the standard spin-on design and 1-14 UNS-2B threaded interface, it is a direct replacement for multiple models like Cummins 3308638 and Donaldson P558000, requiring no professional tools for disassembly and assembly.

• Stable performance in extreme conditions: It operates reliably in various harsh working scenarios of construction, mining and power generation, maintaining consistent filtration and separation efficiency to reduce equipment downtime and maintenance costs.
