Straight Reduction Fitting GR, Carbon Steel, Zn-Ni Coated

The DIN 2353 straight reducing fitting, type GR, is a high‑performance connector designed for reliable and durable hydraulic applications. Featuring a 24° DIN 2353 socket with external metric threads on both sides, it ensures secure and precise connections across a wide range of systems. Available in three series – LL (very light), L (light), and S (heavy) – it offers flexibility to match different pressure requirements and installation conditions. Manufactured from robust carbon steel and finished with an advanced zinc‑nickel coating of 6–10 µm, the fitting delivers outstanding protection against wear and environmental factors. Its superior surface treatment guarantees exceptional corrosion resistance, proven to withstand up to 720 hours in a salt spray chamber without visible damage, making it an excellent choice for demanding industrial environments. Engineered for long service life, easy assembly, and consistent performance, this reducing fitting is an ideal solution for professionals seeking reliability, safety, and efficiency in hydraulic and pneumatic systems.
