Description

The 1CM metric thread hydraulic fitting is a precision-engineered component designed for leak-proof connections in hydraulic and gas systems, featuring a metric thread and integrated captive sealing washer (typically an O-ring). Classified as a "bite type" (DIN bite type) fitting, it secures tubes via a biting mechanism, ensuring robust attachment while complying with DIN and GB standards for universal compatibility.

Available with either a 60-degree seat or 24-degree cone seating, the fitting forms a tight seal against mating surfaces, eliminating fluid leakage even in demanding operating conditions. Crafted from high-quality stainless steel, it offers exceptional corrosion resistance and durability, making it suitable for harsh environments like mining. Common part number variants include 1CM-WD (male) and 1DM-WD (male), with the "/RN" suffix indicating complete sets supplied with a ferrule and nut for ready installation.

Ideal for hydraulic and fluid transport applications—particularly in mining and industrial settings where reliable, leak-free connections are critical—the 1CM fitting balances precision engineering, standardized performance, and rugged construction. It seamlessly connects hoses and pipes, delivering consistent sealing reliability to support the efficient operation of hydraulic and gas systems.
