The 1C9 (light series) and 1D9 (heavy series) 90° elbow fittings are professionally engineered for directional steering of high-pressure hydraulic metric pipeline systems. Adopting standard DIN male thread structure with integral forging and multi-axis CNC precision machining, it realizes smooth 90° fluid redirection in compact equipment space while maintaining stable laminar flow and minimal pressure loss. The precision-machined burr-free threads ensure smooth, gall-free assembly, forming a tight metal-to-metal seal that effectively resists vibration, thermal fluctuations and pressure spikes. Suitable for conveying hydraulic oil, industrial water and compressed gas, it eliminates fluid seepage risks, reduces unplanned downtime, and ensures long-term reliable operation of heavy-duty industrial fluid systems.
Manufactured in full compliance with DIN, SAE and ISO international industry standards, all dimensions and thread tolerances are strictly controlled. The product passes 96-120 hours neutral salt spray test with reliable corrosion resistance, covering working pressure up to 630 Bar (9000 Psi) for light and heavy series. Complete dimensional drawings, thread parameters and pressure rating data can be provided according to customer model requirements, supporting direct drop-in replacement of mainstream brand standard parts.
Reliable Vibration-Resistant Sealing: Precision-machined metric male threads form a tight metal-to-metal seal, effectively preventing fluid leaks under dynamic loads and long-term continuous vibration.
90° Compact Steering Design: Standard right-angle structure realizes optimized pipeline layout in confined mechanical compartments, saves installation space without sacrificing flow capacity.
High-Pressure Resistant Forged Structure: Integral high-tonnage forging eliminates internal voids, enhances structural density and fatigue resistance, safely withstands working pressure up to 630 Bar.
Smooth Anti-Galling Threads: Multi-axis CNC machined threads ensure smooth engagement during assembly, avoid cross-threading and galling, greatly reduce on-site installation labor time.
Low Resistance Flow Channel: Precision polished internal bore minimizes fluid turbulence and pressure loss at the bend, maintains stable and efficient fluid transmission performance.
Carbon Steel (Cr3+ Zinc Plated)
Adopts eco-friendly trivalent chromium zinc plating process, passes 96-120 hours neutral salt spray test without white rust, fully compliant with RoHS directives. It has excellent oxidation resistance, high tensile strength and cost performance, ideal for conventional hydraulic systems, engineering machinery and general industrial working conditions.
Stainless Steel (Passivation)
Through rigorous professional passivation treatment, it forms a dense protective oxide layer, with outstanding acid, alkali and salt spray corrosion resistance, perfectly suitable for petrochemical, marine, mining and other highly corrosive harsh working environments.
This DIN standard metric male 90° elbow fitting is widely used in high-pressure hydraulic pipeline directional connection scenarios in various core industrial fields:
Construction & Earthmoving Machinery: Hydraulic pipeline steering for excavators, bulldozers, loaders and other mobile heavy equipment, adapting to high-vibration field working conditions.
Agricultural & Mining Machinery: Hydraulic system piping for high-horsepower tractors, combine harvesters, deep-shaft mining rigs and crushing equipment, withstanding long-term impact loads.
Industrial Manufacturing: Pipeline layout for automated production lines, hydraulic stations, machine tools, compressed air and cooling water circulation systems.
Petrochemical & Marine Engineering: Medium transmission pipelines for oil and gas, chemical processing systems, ship equipment and offshore platforms, with corrosion-resistant material options for harsh environments.
The fitting body is formed by high-tonnage integral hot forging to optimize metal grain structure, ensuring dense internal matrix and excellent burst pressure resistance. Metric threads and sealing surfaces are processed by multi-axis CNC lathes with micron-level precision. Each batch undergoes 100% leak test, dimensional verification and thread gauge inspection before delivery, fully complying with international standard requirements, ensuring stable and reliable long-term operation under extreme high pressure.
A: The eco-friendly Cr3+ (trivalent chromium) zinc plating provides a robust sacrificial protective layer that actively prevents the oxidation of the underlying steel. By surviving up to 120 hours in demanding neutral salt spray tests without exhibiting white rust, it ensures the fitting remains structurally sound and easy to unthread, even after years of exposure to atmospheric moisture, road salts, and harsh industrial chemicals.
A: Absolutely. The foundational forged body construction eliminates the microscopic internal voids and porosities often found in cheaper cast parts, granting it exceptional burst strength. It is officially rated for maximum working pressures up to 630 Bar (9000 Psi), making it highly resilient against the sudden hydraulic shocks, water hammers, and pressure spikes commonly experienced in excavators, loaders, and hydraulic presses.
A: Forging under high heat and immense pressure aligns the grain structure of the metal specifically to the shape of the 90-degree elbow, maximizing its overall mechanical strength and fatigue resistance. Subsequent multi-axis CNC machining then cuts the metric threads and internal bores with microscopic precision. This dual combination ensures the fitting is both virtually indestructible under heavy loads and perfectly sized for a frictionless, leak-free installation.
A: Yes, the 1C9 and 1D9 series are manufactured in strict, uncompromising accordance with DIN standard specifications. The metric male threads and internal 24-degree cone dimensions are precisely engineered to interface flawlessly with standard bite-type cutting rings and metric union nuts. This guarantees a secure, vibration-resistant, metal-to-metal seal in any globally standardized DIN-compliant fluid system.
A: Post-machining, every single fitting undergoes a rigorous, multi-stage ultrasonic cleaning and flushing process. This highly effective procedure removes all residual cutting fluids, microscopic metal shavings, and fine burrs from the internal fluid pathways. We guarantee a pristine internal bore to prevent any particulate contamination from entering and damaging your highly sensitive hydraulic directional valves or expensive piston pumps.
A: Yes, our advanced R&D and dedicated tooling departments excel at executing custom OEM/ODM manufacturing projects. If your specific fluid routing architecture requires an angle other than 90 degrees, a specialized thread profile, or a unique dimensional length, we can rapidly prototype and subsequently mass-produce the exact fitting based directly on your CAD drawings or physical reference samples.
