Stainless Steel Hydraulic Connectors Product Description
Stainless steel hydraulic connectors are core sealing fittings used in hydraulic systems to connect components such as oil pipes, hydraulic pumps, hydraulic cylinders, and hydraulic valves. Made from stainless steels such as 304 and 316L, they possess three core characteristics: high strength, high sealing performance, and excellent corrosion resistance.
These connectors are precision forged and machined, resulting in high dimensional accuracy and a tight thread engagement. They are compatible with various connection methods, including welding, ferrules, flaring, and crimping. They operate stably under harsh conditions such as high pressure, humidity, and weak acids and alkalis, overcoming the problems of easy corrosion and sealing failure associated with ordinary carbon steel connectors. They are widely used in hydraulic systems with stringent requirements for corrosion resistance and reliability.
Core Uses
Hydraulic System Piping Connections
Acting as a "bridge" between pipelines and hydraulic components, this connector ensures stable hydraulic oil delivery and guarantees efficient system pressure transmission. It is suitable for assembling hydraulic pipelines in heavy equipment such as construction machinery, mining machinery, and marine equipment, preventing oil leaks and pressure drops under high-pressure conditions.
Corrosive Environment Compatibility
Leveraging the corrosion resistance of stainless steel, it can be used in hydraulic systems in chemical, marine, food, and pharmaceutical industries. Examples include connecting hydraulic actuators on chemical production lines, piping for hydraulic equipment on ship decks, and hydraulic transmission systems in food processing machinery, preventing corrosion from media or environmental salt.
High-Precision Equipment Compatibility
Suitable for small hydraulic systems in aerospace, precision instruments, and new energy equipment. Its compact design and precise dimensional tolerances meet the assembly requirements for lightweight and miniaturized equipment while ensuring sealing performance and operational stability.
High and Low Temperature Applications
The excellent thermal stability of stainless steel allows this connector to operate normally within a wide temperature range of -40℃ to 200℃, making it suitable for special scenarios such as high-temperature hydraulic systems in metallurgy and hydraulic pipelines in cold chain equipment.
| Standard Type | Fitting Type | Core Dimensional Parameters | Common Specification Range | Key Supplementary Notes |
| ISO 8434 | 24° Cutting Ring Hydraulic Fittings | The outer diameter of the tube ranges from 4 mm to 42 mm; it adopts a cutting ring sealing structure, suitable for ferrous and non-ferrous metal tubes with corresponding outer diameters. | Tube outer diameter: 4mm, 6mm, 8mm, 10mm, 12mm, 15mm, 18mm, 22mm, 28mm, 35mm, 42mm. | Compatible with oil ports conforming to standards such as ISO 6149 - 1. The working pressure is 10MPa - 63MPa, divided into three series: LL, L, and S. |
| GB/T 3733 | Cutting Ring Straight-through Tube Fittings | Basically consistent with ISO 8434 - 1 in dimensions, with the tube outer diameter of 4 - 42 mm. It adds F-type, E-type, and B-type threaded stud ends, and the A-type stud end is supplemented with 55° non-sealing pipe threads (G). | Same as the common tube outer diameter specifications of ISO 8434. Thread specifications include M10×1, M12×1.5, ZG1/8, ZG1/4, etc. | The maximum working pressure is 10MPa - 63MPa. It integrates two previous old standards and cancels the marking of weight and surface roughness. |
| SAE J514 | JIC 37° Flared Fittings / NPT Threaded Fittings | JIC type features a 37° tapered seat with UN/UNF series threads; NPT threads have a 60° thread angle, with specifications ranging from 1/8″ to 2″. For example, 1/8″NPT (27 threads per inch), 1/2″NPT (14 threads per inch). | 1/8″, 1/4″, 3/8″, 1/2″, 3/4″, 1″, 1.25″, 1.5″, 2″. | Tailored for the North American market. NPT threads rely on metal sealing and are widely used in hydraulic systems of construction machinery and agricultural machinery. |
| JIS B 8363 | 30° Flared Hydraulic Fittings | Threads comply with the BSPP (PF/G) standard; suitable for hydraulic hose assembly fittings of corresponding specifications. | Common thread specifications: 1/8BSPP, 1/4BSPP, 3/8BSPP, etc., adapted to tubes with an outer diameter of 6 - 38 mm. | Specifically designed for the Japanese market.
