This essential part contributes significantly to the engine’s durability and reduces maintenance needs over long service intervals.

Jacketed packing rings with code EN14U2429 are advanced sealing elements used in critical areas of the MAN L21/31 engine where high-performance sealing is required. Featuring a soft core (often graphite or PTFE) surrounded by a durable metal jacket, these rings combine flexibility with strength, adapting to surface imperfections while resisting extreme heat and pressure. They are commonly installed in exhaust, cylinder, or high-pressure sealing areas, ensuring leak-proof performance and long-term durability.

The oval packing, code EN14DB029052, is a specially shaped sealing element designed for the MAN L21/31 engine to ensure a tight fit between mating surfaces. Often used in valve housings or flanged joints, its oval geometry provides superior surface contact, enhancing its ability to prevent oil, fuel, or gas leaks under variable loads. Its resilience to heat, pressure, and chemical exposure makes it a key component in maintaining engine reliability and environmental safety.

Plug screws with code EN47AR10 are essential sealing and closure components within the MAN L21/31 engine. Typically used to block access points, inspection holes, or internal fluid pathways, these screws are engineered to withstand high pressure and temperature fluctuations. Their robust, corrosion-resistant construction ensures a tight and lasting seal, contributing to engine integrity and preventing fluid leaks during demanding marine or industrial operation.

The complete damper end cover with code K 16500 is an integral part of the engine’s vibration dampening system, located at the far end of the crankshaft in the ZV40/48 engine. This component encloses the torsional damper mechanism, protecting it from mechanical damage and environmental exposure. Designed to withstand the effects of rotating mass forces, heat, and oil exposure, the cover ensures the proper functioning of the damper, which reduces engine vibration and mechanical stress. Its robust construction contributes to smoother engine operation and extends the life of connected rotating assemblies.

The ring coded K 27010 is a specially designed support and locking element used in combination with component K 27008 in the ZV40/48 engine assembly. It ensures secure positioning and mechanical stability of the mating part, particularly under dynamic engine conditions involving vibration, thermal expansion, or pressure fluctuations. Manufactured with tight tolerances and wear-resistant materials, this ring plays an important role in maintaining sealing integrity and axial alignment. Its durable construction helps extend the lifespan of the assembly and supports reliable engine operation in harsh industrial and marine environments.

The cover with code K 27007 is a vital protective component used in conjunction with the bearing casing K 28000 in the Sulzer ZV40/48 diesel engine. Its primary function is to shield the bearing assembly from external contaminants such as dust, oil mist, and moisture, while also helping to retain internal lubrication. Precision-machined from corrosion-resistant materials, this cover ensures long-term protection of the rotating elements, preserving the alignment and performance of the engine's drive train. By minimizing wear and preventing ingress of harmful particles, it contributes to smoother engine operation and reduced maintenance needs.

The silicone paste sealing material, code EN14AM0.001, is a versatile and high-performance compound used in the MAN L21/31 engine for sealing joints and preventing fluid leaks. Applied during assembly between metal surfaces such as flanges or covers, it fills microscopic gaps and resists heat, oil, and pressure. This packing material enhances engine cleanliness and reduces maintenance by maintaining tight seals over extended service intervals, even under harsh operational conditions.

The hexagon collar nut, code EN89DE12, is a specialized fastening component designed for use with studs in the MAN L21/31 engine. Its collar provides a larger bearing surface, improving load distribution and resistance to loosening from vibrations. Engineered for use in high-torque and high-temperature environments, this nut contributes to consistent clamping force, sealing effectiveness, and long-term joint reliability, especially in critical engine assemblies like cylinder and exhaust systems.
