The compression fitting, code 100100, is an essential joining element within the MAN L21/31 engine systems, designed to create secure and pressure-resistant connections between pipes or tubing without the need for welding. By using controlled mechanical compression, it forms a reliable seal that prevents leakage of fluids or gases even under high-pressure operating conditions. Precision-manufactured from durable and corrosion-resistant materials, the fitting provides long-lasting performance in demanding marine and industrial environments. Its ease of installation, maintenance efficiency, and dependable sealing capability make the compression fitting an important component for maintaining system safety, operational stability, and efficient fluid handling throughout the engine.
