Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
3912473 Cummins Engine Grade NBR Rubber Round O-Ring Seal
Oil Resistant Nitrile Rubber Circular Seal Ring for Engine Replacement
This model NBR O-ring is manufactured strictly in accordance with original part specification, fully meeting assembly demands of Cummins related engine components. It overcomes common defects of inferior sealing rings like easy aging, oil swelling and poor elasticity. With fine compression resilience and structural uniformity, it can adapt to frequent vibration and slight gap changes during equipment operation, acting as a basic and crucial sealing component for engine internal connection positions.

1. Product Advantages
This NBR rubber O-ring features outstanding oil resistance and compression recovery capacity, keeping stable shape and elasticity after long-term compression without permanent deformation, and it effectively resists erosion of various engine lubricating oil and hydraulic oil to avoid swelling and cracking. Standard dimensional precision ensures smooth assembly and good fit, fine vibration resistance adapts to running fluctuation of engine, and durable material greatly reduces replacement frequency while lowering daily equipment maintenance cost.
2. Installation Recommendation
3.. Working Principle
After being embedded into the fixed sealing groove, the O-ring will generate elastic compression deformation under the squeezing of two fitting surfaces. The tightly attached ring body fills assembly gaps completely to form an effective isolation layer. It blocks internal medium from leaking outward and prevents external dust and impurities from invading inside equipment, maintaining sealed and clean operating environment of engine internal pipelines and cavities.
4. Product Details
The whole product is molded from high purity NBR raw rubber with precise size consistent with 3912473 original standard. The surface is smooth and free of bubble, crack and uneven defect, possessing uniform hardness and good flexibility. Finished products are screened one by one to guarantee qualified sealing performance. Adopts moisture-proof and dust-proof independent packaging, convenient for storage, transportation and field replacement use.
5. Application Range
Specially applicable to matching sealing of Cummins corresponding model engines, widely used in engine oil passage, gas port, pipeline joint and cavity assembly positions. It is suitable for sealing protection of mechanical power equipment working with conventional oil medium.
