The 1CH9 is a precision-engineered 90-degree elbow hydraulic fitting featuring metric thread adjustable stud ends, tailored for compatibility with metric bite-type tube fittings. Designed to redirect fluid flow efficiently in hydraulic systems, its adjustable stud ends allow orientation fine-tuning during installation—enabling seamless integration into complex layouts before secure tightening, delivering exceptional versatility.
Compliant with ISO 6149 standards (Metric Thread O-Ring Face Seal Fittings), this fitting ensures reliable, leak-proof connections via an O-ring washer seal, making it ideal for high-pressure applications. Crafted from durable carbon steel or stainless steel, it boasts robust construction to withstand harsh industrial conditions, while surface treatments such as zinc plating, chrome plating, nickel plating, or zinc-nickel plating enhance corrosion resistance and service life.
Suitable for diverse industrial scenarios, the 1CH9 excels in manufacturing plants, construction sites, and general hydraulic systems handling water, oil, or gas media. By combining directional flexibility, standardized sealing performance, and durable materials, it delivers consistent reliability for critical fluid transfer, embodying engineering excellence for high-pressure hydraulic system requirements.
