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.

MAN L21/31; PLUG SCREWS (Code EN47AR10)

Written by

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.
