Manufactured in strict accordance with DIN international industrial standards, all dimensional tolerances of metric female threads, 24° DKO cone sealing surface and 45° steering angle are strictly controlled at micron level. It is fully compatible with standard metric hydraulic hoses and supporting adapters on the market. Complete dimensional drawings, thread parameters and pressure rating data of full series models can be provided according to customer requirements.
45° Optimized Flow Design: Reasonable bevel steering structure minimizes internal fluid turbulence and pressure loss, reduces hose bending deformation, and extends the service life of the entire pipeline system.
DKO 24° Cone Reliable Sealing: Standard cone sealing structure forms a stable sealing interface, effectively blocking fluid seepage, and maintaining tight performance even under continuous vibration and pressure fluctuations.
Forged High-Strength Structure: Integral hot forging optimizes the metal grain structure, eliminates internal voids, enhances burst pressure resistance, and effectively prevents thread loosening during long-term heavy-duty operation.
Precision Machining for Easy Assembly: CNC precision cut metric female threads ensure smooth and gall-free engagement during installation, greatly reducing on-site assembly labor time and difficulty.
Wide Media & Scenario Adaptability: Material and structure are optimized to be compatible with various industrial media, suitable for diversified hydraulic and fluid pipeline systems.
Carbon Steel (Cr3+ Zinc Plated)
Adopts environmentally friendly trivalent chromium zinc plating process, which has excellent rust and oxidation resistance, complies with global environmental regulations, has high tensile strength and cost performance, and is suitable for conventional industrial hydraulic systems and general equipment pipeline scenarios.
Stainless Steel (Passivation)
Through rigorous professional passivation treatment, free iron on the surface is removed, a dense protective oxide layer is formed, with outstanding acid, alkali and salt spray corrosion resistance, suitable for petrochemical, marine, high humidity and other harsh corrosive working environments.
This 45° metric female DKO hose fitting is widely used in high-pressure hydraulic hose steering connection scenarios in various core industrial fields:
Construction & Agricultural Machinery: Hydraulic hose directional layout for excavators, loaders, tractors, harvesters and other mobile heavy equipment, adapting to the compact space of the whole machine.
Industrial Manufacturing & Metallurgy: Hydraulic circuit connection, fluid pipeline steering for machine tools, automated production lines, metallurgical processing equipment and pressure conveying systems.
Petrochemical Industry: Oil and gas transmission pipelines, chemical medium delivery systems, with corrosion-resistant material options to adapt to complex and harsh medium environments.
Marine & Offshore Engineering: Supporting hydraulic hose fittings for ship machinery, offshore platform fluid pipeline systems, with high pressure resistance and corrosion resistance to adapt to marine working conditions.
General Hydraulic Systems: Pipeline steering assembly of high-pressure hydraulic stations, pneumatic control equipment, industrial cooling water and compressed gas conveying systems.
The fitting body is formed by high-tonnage integral hot forging to ensure dense internal structure and excellent mechanical properties. Metric female threads and 24° DKO cone sealing surfaces are processed by multi-axis CNC lathes with micron-level precision. Each batch undergoes strict thread gauge inspection, dimensional verification, pressure sealing test and surface quality inspection before delivery, fully complying with DIN standard requirements, ensuring stable and reliable long-term operation in high-pressure hydraulic systems.
