The Stainless Steel Hydraulic Pipeline Double Ferrule of XYOON is a precise sealing component designed for high-pressure corrosive conditions. It achieves dual metal sealing through a stepped deformation sealing structure. It is meticulously manufactured from 304/316L stainless steel and undergoes rigorous salt spray, vibration and pressure resistance comprehensive tests. It fully complies with ISO and DIN international pipeline standards.
A stainless steel hydraulic pipeline double ferrule is a precision sealing component consisting of front and back ferrules for compression connections. When tightened, the back ferrule drives the front ferrule to form a primary metal-to-metal seal, then locks onto the pipe for secondary sealing and anti-vibration grip. Unlike carbon steel ferrules, it offers exceptional corrosion resistance, making it the gold standard for critical hydraulic systems.
1. Dual Redundant Sealing: Eliminates Pipeline Leakage at the Source
Pipeline Value: Leakage causes 30% of industrial equipment downtime globally. Our stepwise deformation design creates two independent metal-to-metal seals: the front ferrule forms a 360° uniform primary seal against the pipe and fitting body, while the back ferrule provides secondary sealing and mechanical locking.
2. Military-grade Anti-vibration: Prevents Pipeline Loosening Under Extreme Conditions
Pipeline Value: 60% of hydraulic failures in mobile machinery are caused by connection loosening under vibration. Our back ferrule embeds 15%-20% into the pipe wall, forming a permanent mechanical lock that cannot be loosened by vibration.
3. Superior Corrosion Resistance: Extends Pipeline Service Life in Harsh Environments
4. Perfect System Compatibility: Plug-and-play with All Standard Pipelines
Custom materials, sizes, surface treatments and laser marking
Production process: Raw material inspection → Cold extrusion → Heat treatment → Leak testing → Packaging
The entire double ferrule forming and sealing process strictly follows the two major global mainstream hydraulic pipeline standards, ISO 8434-1 and DIN 2353. The specifications and sizes are compatible with mainstream brands worldwide and can be interchanged. There is no need for additional modifications for the export to Europe, Asia, and the Middle East.
All Stainless Steel Hydraulic Pipeline Double Ferrule products undergo 1500 hours of neutral salt spray corrosion resistance test, 10 million cycles of vibration durability test, and 63 MPa high-pressure leak-free pressure resistance test upon completion of production. Each batch comes with the original factory test report. The 316L electrochemical polishing model complies with FDA food contact usage specifications and can be used in pharmaceutical and food clean pipelines.
Four closed-loop quality inspections include raw material inspection upon entry, cold extrusion forming inspection, heat treatment hardness test, and finished product sealing pressure test. An EN10204 3.1 material certificate is issued. Each batch of goods comes with compliant Chinese and English materials, facilitating customs clearance for overseas customers and factory acceptance.
Under the conditions of correct selection, proper installation, and standard usage in normal circumstances, the original factory provides a 12-month warranty. The warranty period is calculated from the date when the customer signs for the goods.
The warranty covers defects in raw materials and processing flaws that cause leakage and cracking. Faults not caused by human factors can be replaced with brand-new sleeves free of charge. Faults caused by violent disassembly, overpressure and overtemperature usage, or scratches on the pipe surface are not covered by the warranty.
Before-sales: Free pipe sample and technical solution for selecting working conditions are provided. For bulk purchases, laser marking and customized special surface treatment are supported. After-sales: 7x16-hour English technical communication is available. Problems related to sealing assembly and leakage detection can be answered within 24 hours. Commonly available spare parts are replenished in bulk. Overseas, samples and spare parts can be separately delivered in small packages.
Offered to distributors and large equipment factories, the wholesale price for a complete order is provided. Long-term cooperative customers can reserve safety stock. A set of pre-installed and assembled teaching graphics and video manuals are also provided.
Before installation, it is necessary to clean the sharp edges, oxide scale, and scratches on the outer wall of the pipe. Any damage to the pipe wall will directly compromise the metal seal. The pre-installation should be completed using the factory's ferrule pre-installation machine. Lock the nuts according to the standard torque to avoid insufficient force or overpressure compression deformation.
Conduct weekly inspections of the pipe joint positions and apply soapy water to check for minor leakage traces. In chemical and coastal high-salt spray environments, inspect the surface rust of the joints monthly. Clean up the residual medium in a timely manner.
Stainless Steel Hydraulic Pipeline Double Ferrule is a one-time sealing consumable. After disassembling the pipeline, the front and rear ferrules must be replaced simultaneously. They cannot be reused. The body of the joint and the locking nut have no deformation, and they can be reassembled.
For the idle inventory ferrules, ensure they are sealed against moisture. Although 316L material is corrosion-resistant, it will still develop surface oxidation over time when exposed to high humidity. The storage environment should avoid contact with acid and alkali gases.
For the pipe lines of vibrating construction machinery, preferentially select the thickened and reinforced double ferrule model. Regularly check the pre-tightening force of the nuts to avoid long-term vibration causing loosening and leakage of the connection.
Q: 304 vs 316L stainless steel?
A: 304 for general industrial use; 316L with molybdenum for marine/chemical applications.
Q: Compatible with other brands' pipes?
A: Yes, fully compliant with ISO 8434-1 and DIN 2353 standards.
Q: Suitable for food/pharmaceutical use?
A: Yes, 316L electropolished ferrules meet FDA food contact standards.
Q: Can ferrules be reused?
A: Body and nut can be reused; replace front/back ferrules each disassembly.
Q: Does the stainless steel hydraulic pipeline double ferrule pipe need to undergo pipe end pretreatment?
A: Yes, the pipe ends must be flat and free of burrs, and the outer wall must be free of scratches and marks. It is recommended to use a pipe cutting machine and a deburring machine to complete the pipe pre-treatment, so as to ensure no leakage in the double-layer seal.
Q: For high-temperature medium conditions, should we choose 304 or 316L material?
A: For normal medium-temperature water routes, 304 is selected; for temperatures exceeding 180℃ and corrosive media such as acids and alkalis, 316L stainless steel with molybdenum elements in double ferrule must be used.
Q: Is it possible to customize double flange molds with non-standard special pipe diameters?
A: Yes, we can customize the molds according to the specific outer diameter and wall thickness of the customer's pipe material. Additionally, we offer two surface treatment options: matte finish and electro-polishing.
Q: Can the double card clamp be directly used with other brands' pre-installed card clamp machines?
A: It is fully compatible. The size conforms to DIN and ISO standards, and it is suitable for the vast majority of hydraulic card clamp pre-installation equipment on the market. No additional adjustments to the assembly parameters are required.
