The ring with code 11.01299-0128-1.A is a general-purpose component used within the MAN L21/31 engine assembly to ensure proper alignment or sealing between parts. It may serve in various mechanical couplings where durability and precision fit are essential. Despite its small size, it contributes significantly to the integrity and longevity of the engine system.
The Teflon ring with code 11.01299-0128.A offers exceptional sealing and friction-reducing performance for the MAN L21/31 engine. Known for its excellent thermal resistance and low wear properties, Teflon ensures stable operation even under harsh conditions. This ring is typically used in dynamic sealing zones where flexibility, chemical inertness, and low maintenance are required.
The round seal ring, code 06.56936-1507-1.0, is a critical sealing component in the MAN L21/31 engine, ensuring leak-free connections in various fluid systems. Whether used in lubricating, cooling, or fuel circuits, this high-quality ring resists pressure, heat, and chemical exposure. Its reliability is key to maintaining engine cleanliness and operational efficiency during prolonged marine or industrial use.
The conical disc with code K 21005 is an essential pressure-distribution component used with clamping pieces in the engine. Its conical shape helps evenly distribute load forces across the contact surface, reducing localized stress and enhancing mechanical stability. By improving the connection between fasteners and structural elements, this disc plays a crucial role in minimizing fatigue and prolonging the life of the engine’s critical joints.
The bolt identified as K 21002 plays a vital role in securing the clamping pieces that hold key engine components in place. Engineered for high strength and vibration resistance, this bolt withstands substantial mechanical loads during operation. Its precise threading and high-grade material ensure reliable fastening, making it indispensable for maintaining structural integrity and alignment throughout the engine’s working life.
The O‑ring with code K 21404 is a critical sealing element designed for the cylinder liner of the engine. Its primary function is to provide a leak‑proof barrier between the liner and engine block, preventing coolant and combustion gases from mixing. This component endures high temperatures and pressures, maintaining its integrity even under intense thermal cycling. A properly functioning O‑ring is essential for preserving compression and ensuring optimal engine performance over long operational periods.
