The DIN 2353 straight reducing fitting, type KORO-S heavy series, is a precision-engineered hydraulic component designed for reliable performance in demanding applications. Featuring a 24° DIN 2353 socket with O-ring, it ensures secure and leak-free connections, combining an internal metric thread with an external metric thread for versatile installation. Available in both light (L) and heavy (S) series, this fitting offers flexibility to match diverse system requirements. Manufactured from high-quality carbon steel and finished with a zinc-nickel coating of 6–10 µm, it delivers exceptional durability and outstanding corrosion resistance, proven to withstand up to 720 hours in a salt spray chamber without visible corrosion. This advanced protective layer significantly extends service life, even in harsh environments, reducing maintenance costs and downtime. Engineered for strength, reliability, and long-term efficiency, the KORO-S reducing fitting is the ideal choice for hydraulic systems where safety, performance, and resistance to extreme conditions are essential.
