The Hydraulic Pipeline Ferrule covers all types and specifications of single and double flange sleeves. It is made with a stable sealing structure based on the original factory's gradient hardness heat treatment process, and is suitable for all pipe diameters ranging from 3 to 50 mm and all pressure conditions ranging from 16 to 63 MPa. The product fully complies with international standards such as DIN, ISO, and SAE. It undergoes millions of vibration durability tests before leaving the factory. We can provide wholesale, OEM rebranding, and customized non-standard sizes. It is suitable for all industries including engineering, oil and gas, and ships. Long-term use can reduce the overall costs of equipment downtime and pipeline replacement.
A hydraulic system is only as reliable as its weakest connection—and that connection is almost always the ferrule. Statistics show that 70% of hydraulic system failures originate from poor ferrule performance, leading to costly downtime, fluid leaks and safety hazards. Many customers underestimate the importance of this small component, choosing low-quality ferrules that fail prematurely.
Kuncheng hydraulic pipeline ferrules are engineered to be the strongest link in your hydraulic system. We offer a complete range of single and double ferrules in multiple materials and sizes, designed to meet the exact requirements of every application from general industrial to extreme environment.
Full-Range Product Coverage: 200+ standard specifications covering 3mm-50mm pipe diameters and 16MPa-63MPa pressure ratings, including both single and double ferrules for all industrial applications.
Proprietary Gradient Hardness Technology: Unique heat treatment creates a hardness gradient—sharp cutting edge for pipe penetration and flexible body for vibration absorption, eliminating cracking and sealing issues, extending service life by 3x.

The entire series of Hydraulic Pipeline Ferrules are produced strictly in accordance with the three major international fluid pipeline standards of DIN 2999, ISO 8434, and SAE J514. The dimensions, hardness, and sealing parameters are compatible with the main brands in Europe and America. There is no need to adjust the specifications when exporting to various countries, and the products can smoothly pass customs and on-site acceptance by the customer.
Each batch of goods comes with complete inspection materials, including size tolerance inspection sheets, hardness test records, 63MPa high-pressure leakage test reports, and million-cycle vibration cycle test certificates. Customized EN10204 3.1 material traceability certificates can be issued as needed. The steel furnace batch number can be fully traced throughout the process, meeting the requirements of large equipment factories and overseas engineering bidding documents.
The product has obtained CE mechanical safety certification, which complies with the EU fluid equipment access regulations. The stainless steel corrosion-resistant model can be accompanied by a salt spray third-party test report. A complete set of compliance documents is provided to customers for purchasing in shipbuilding, chemical, and food clean environments, avoiding market access barriers in overseas markets.
The factory holds ISO9001 quality management system certification. The fully automated numerical control production line conducts closed-loop management throughout the process. The measuring and testing equipment is regularly calibrated, and production records of all processes are retained. Customers can apply for factory video inspection and batch process rechecking.
When the product is properly pre-installed, under standard pressure and with compatible pipe materials, the original factory provides a 12-month warranty. The starting date of the warranty is based on the date when the customer's goods are signed for. Defects in raw materials, defects in heat treatment processes, and leakage or cracking caused by substandard sealing performance during factory sealing will be free of charge replaced with brand new ferrules.
Damage caused by violent pre-installation by humans, long-term operation at over 63 MPa pressure, scratches or corrosion on the outer wall of the pipe material, and sealing failure caused by repeated disassembly and reuse of ferrules are not covered by the free warranty; Installation specifications will be informed before sale to avoid human wear and tear issues in advance.
Before sale, multiple specifications of samples can be sent for on-site testing. Technicians will recommend single or double ferrule selection based on the customer's equipment pressure and vibration intensity. Laser marking and customized special anti-rust coatings are supported for bulk purchases.
After sale, English-speaking dedicated technical support is provided. Responses to inquiries about pipeline leakage and pre-installation faults will be within 24 hours. Regularly stocked inventory is available. Small packages of spare parts can be directly sent across borders to reduce the waiting time for customers' production lines.
Long-term cooperative distributors and large equipment manufacturers can reserve safety stocks to ensure stable delivery during peak seasons. A bilingual pre-installation operation manual is included for bulk purchases, and when used with the factory's ferrule pre-installation machine, a complete set of pipeline assembly guidance can be provided.
Most manufacturers only produce one type of product, such as a single pipe diameter or single/double flared couplings. Purchasing requires comparing prices from multiple vendors. We have over 200 standard specifications for unified production, covering all commonly used pipe diameters from 3mm to 50mm. We supply products in carbon steel, stainless steel, and alloy steel. A single order includes all pipeline sealing accessories, simplifying the procurement reconciliation and logistics process.
Most ordinary flared couplings have a single hardness design, which is prone to cracking or poor engagement under high-pressure vibration. Our factory has a unique segmented heat treatment process. The cutting edge has sufficient and stable hardness to cut into the pipe wall, and the main body has sufficient toughness to absorb the continuous vibration of the equipment. The measured service life is three times that of ordinary flared couplings, significantly reducing the frequency of pipeline rework and lowering the customer's subsequent operation and maintenance costs.
Most manufacturers only test individual flared couplings. They do not match nuts, connectors, and steel pipes for testing. All our models have completed the entire pipeline assembly test. It simulates the customer's real working conditions to verify the sealing effect. This significantly reduces on-site assembly size mismatches and poor engagement, resulting in reduced rework losses and lowering the customer's subsequent operation and maintenance costs.
As a professional Manufacturer and Supplier of Hydraulic Pipeline Ferrules in China, all processes are completed in the factory. There are no multiple layers of trade premiums. Under the same sealing durability performance, the customer's pipeline comprehensive procurement costs can be reduced by 35%. Direct delivery of goods shortens the delivery time, and long-term bulk purchases can negotiate a stepped wholesale price.
Q1: When should I use a single ferrule vs a double ferrule?
A: Single ferrules are ideal for medium-pressure (up to 40MPa) applications with moderate vibration, such as general industrial machinery. Double ferrules are recommended for high-pressure (up to 63MPa) and high-vibration applications, such as construction machinery and offshore platforms.
Q2: How many times can a hydraulic pipeline ferrule be reused?
A: Ferrules are designed for one-time use only. Once deformed during installation, they cannot provide the same level of sealing performance if reused. The nut and fitting body can be reused multiple times.
Q3: How should I store ferrules to prevent damage and corrosion?
A: Store ferrules in their original sealed packaging in a dry, cool place away from moisture, chemicals and direct sunlight. Carbon steel ferrules have a 12-month shelf life with proper storage, while stainless steel ferrules can be stored for up to 24 months. Do not remove the anti-rust coating until installation.
