The 00400 hose ferrule is professionally engineered for 4SH and 4SP four-wire spiral high-pressure hydraulic hoses, serving as the core crimping component for heavy-duty fluid line connections. Adopting integral forging and CNC precision machining, it features an optimized internal bite ridge structure, which can evenly and deeply embed into the hose's steel wire reinforcement layer during crimping, forming a permanent, gap-free tight lock. It effectively eliminates hose slippage, fluid bypass and hazardous blowout risks under extreme vibration, pressure spikes and harsh working conditions. Suitable for conveying hydraulic oil, industrial water and compressed gas, it significantly reduces unplanned system downtime, and ensures long-term stable operation of high-pressure hydraulic circuits.
Precision Bite Ridge Design: Optimized angled internal ridges evenly grip the four-wire spiral reinforcement layer, completely preventing hose slippage under severe dynamic loads and pressure impulses.
High-Density Forged Structure: High-tonnage forging forms a uniform metal grain structure, eliminating internal voids and porosity defects common in cast products, greatly improving burst resistance and fatigue resistance.
Smooth & Efficient Assembly: Precisely chamfered edges allow for effortless insertion over skived hoses, reducing assembly friction and operator fatigue, significantly accelerating the crimping workflow.
Wide Media Compatibility: Stably adapts to various industrial media, including high-viscosity hydraulic oil, industrial water, and compressed gases, meeting the needs of diverse application scenarios.
Superior Corrosion Resistance: Professional surface treatment forms a dense protective barrier, effectively resisting industrial corrosion, moisture oxidation, and harsh environmental erosion, extending service life.
Carbon Steel (Cr3+ Zinc Plated)
Adopts eco-friendly trivalent chromium zinc plating process, with excellent rust and oxidation resistance, high tensile strength and outstanding cost performance, ideal for conventional heavy-duty hydraulic systems, construction machinery and general industrial high-pressure working conditions.
Stainless Steel (Passivation)
Through rigorous professional passivation treatment, free iron on the surface is removed to form a dense and stable protective oxide layer. It has excellent acid, alkali and salt spray corrosion resistance, perfectly suitable for marine, petrochemical and other highly corrosive harsh working environments.
This 4SH/4SP special hose ferrule is widely used in high-pressure hydraulic pipeline crimping connections in various core industrial fields:
Construction & Earthmoving Machinery: Essential for high-pressure hydraulic arms and drive systems of excavators, bulldozers and wheel loaders, adapting to dusty, high-vibration field working conditions.
Agricultural Heavy Machinery: Used for hydraulic pipeline systems of combine harvesters and high-horsepower tractors, resistant to long-term exposure to fertilizers, soil erosion and harsh outdoor weather.
Mining Operations: Built for high-pressure hydraulic lines of underground drilling rigs, crushers and heavy material conveyors, adapting to highly abrasive, strong impact extreme underground working conditions.
Industrial Manufacturing & Injection Molding: Applied to high-pressure hydraulic systems of injection molding machines and metal stamping equipment, ensuring precise and stable pressure output for continuous industrial production.
Marine & Offshore Engineering: Stainless steel version is ideal for hydraulic pipelines of ship deck equipment, port cranes and offshore oil platforms, with excellent resistance to salt spray and marine corrosive environments.
The ferrule is formed by high-tonnage integral hot forging to optimize the internal metal grain structure, ensuring a dense and defect-free matrix. All internal ridges, inner bores and outer circles are processed by multi-axis CNC machine tools with micron-level precision, ensuring uniform wall thickness, perfect coaxiality and consistent dimensional accuracy.
We implement a strict full-process quality control system: incoming raw materials must undergo full testing of tensile strength and chemical composition; full-dimensional inspection is carried out during production; finished products are subject to random sampling tests including 1.5 times rated static pressure test, destructive burst test, hundreds of thousands of dynamic impulse fatigue tests. Each unit is also inspected by optical equipment to ensure no burrs, chips or processing defects, fully meeting industrial quality standards.
To assist your engineering and procurement teams, we have compiled answers to the most common technical and operational inquiries regarding our ferrule fittings.
A: The internal ridges are precisely engineered to displace the outer rubber cover (if skived) and interlock directly with the high-tensile steel wire spirals. This creates a formidable mechanical bond that prevents the hose from pulling out or blowing off under extreme hydraulic pressure and dynamic flexing.
A: Absolutely. While our standard carbon steel features premium Cr3+ zinc plating and our stainless steel is chemically passivated, we can accommodate custom plating requests, such as zinc-nickel alloy coatings, depending on your specific environmental requirements and order volume.
A: Simply provide us with your technical drawings or physical samples. Our engineering team will review the specifications, provide a precise quotation, and produce a physical prototype for your approval. Once the sample is validated by your quality control team, we immediately proceed to mass production.
A: Every single adapter and fitting is fitted with heavy-duty plastic protective end caps immediately after final inspection. They are then sealed in moisture-resistant plastic bags and packed tightly into robust, standard blank cartons to completely prevent any metal-to-metal collision or environmental damage during shipping.
A: For standard 00400 ferrules, we typically maintain a comprehensive, ready-to-ship inventory across most common sizes. Therefore, mixed sample orders or small batches can often be dispatched very quickly, bypassing the standard 30-day lead time required for large-scale, out-of-stock bulk manufacturing.
