Different Types of Hydraulic Fittings

JIC Hydraulic Fittings

JIC (or Joint Industry Committee) hydraulic fittings are compression fittings with a 37-degree flared seating surface and parallel threads and consist of three components that make up the line assembly: the fitting, the flare nut, and the sleeve. They are typically made of brass, carbon steel, and stainless steel. They do not use O-ring seals, are suitable for high-temperature applications, and can be repeatedly disconnected and reconnected without distortion, making them suitable for use in fuel transfer, shipbuilding, mobile hydraulic equipment, and more.

One-piece Hydraulic Hose Fittings

One-piece Hydraulic Hose Fittings are rings that can be pre-crimped onto hose fittings. Also known as pre-crimped hydraulic fittings. This design ensures that hose fittings and sealing gaskets fit correctly, that the collar will not slip, and that hose assembly is easy and quick. Because its inherent strength and leak-proofness make it the preferred choice for harsh environments, one-piece Hydraulic Hose Fittings are simple, fast, and efficient, with little to no maintenance costs later.

Metric Hydraulic Fittings

Metric DIN 2353 fittings are the world's most widely used bite type fittings and do not require an o-ring to provide a seal. Compatibility. Metric threads are like the “universal remote control” of the hydraulic world, working in almost any environment. Metric threads generally provide a better seal. Better sealing means less leakage! Key application scenarios: Mining, agriculture, automotive, from power steering to braking systems, metric fittings ensure seamless operation.

BSP Hydraulic Fittings

BSP Thread Types, Parallel Thread: BSPP for medium and high pressure hydraulic systems Tapered Thread: BSPT for high pressure systems. British Standard Pipe Threads (BSP) are a comprehensive set of thread standards commonly used for joining pipes and fittings. Its durability saves money. BSP hydraulic fittings are suitable for low-pressure fluid transfer systems up to 3,000 psi (approximately 20.7 MPa). Fractional standard hydraulic fittings are used in a wide variety of applications, such as hydraulic, pneumatic, and water, oil, and other media transfer systems.

DIN Hydraulic Fittings

DIN hydraulic fittings are hydraulic fittings designed and manufactured in accordance with the German Industrial Standard (Deutsches Institut für Normung, or DIN). DIN fittings consist of three parts - a fitting body with a conical thread, a nut and a sleeve: DIN fitting types: DIN 2353, DIN 3865, DIN 3852. DIN fittings are resistant to high pressure and have a secure, leak-free connection. DIN couplings are resistant to high pressure, provide a secure, leak-free connection, and are easy to install and disassemble.

Hydraulic Crimp Fittings

Hydraulic Crimp Fittings is a fitting used to connect hoses in hydraulic systems. It consists of a metal collar or sleeve that is permanently attached to the hose by a process known as drop forging. Materials: stainless steel, carbon steel or brass are available. Drop forging uses a specialized tool or machine to compress the collar onto the hose, creating a secure and leak-proof connection.Hydraulic Crimp Fittings connects hoses to other hydraulic components such as pumps, cylinders, actuators, tools, etc. They are designed to withstand high levels of pressure and prevent leakage.

stainless steel hydraulic fittings

Stainless steel hydraulic fittings are mainly made of stainless steel and are used in hydraulic systems to connect, control or transmit components of hydraulic media. Such as 304 (general purpose), 316 (higher corrosion resistance, suitable for marine/chemical environments), users will choose according to the usage environment (acid and alkali, salt spray, high temperature, etc.).

hydraulic banjo fittings​

Hydraulic banjo fittings usually consist of a fitting body, a ball and seals. The fitting body has threads or flanges for connecting with hydraulic system pipes, while the ball head is connected to the fitting body by articulation, allowing rotation and swing within a certain range, divided into light series and heavy series.

NPT Hydraulic Fittings

NPT hydraulic fittings are designed with tapered threads, this design not only enhances the sealing performance of the fittings, but also effectively prevents leakage problems. The thread taper is 1:16 and the thread cross-section is round, which is manufactured in strict accordance with American standards.

1/4 hydraulic hose fittings

1/4 The nominal diameter of hydraulic fittings (such as 1/4 inch, about 6.35 mm), usually corresponds to the thread size or pipe inner diameter, and is used in small and medium flow hydraulic systems.

3/4 hydraulic hose fittings

3/4 hydraulic hose fittings have a nominal diameter of 3/4 inches (about 19.05 mm) and are suitable for medium and high flow hydraulic systems and are often used to connect pipes with larger diameters.

3/8 hydraulic fitting

3/8 hydraulic fitting corresponds to a nominal diameter of approximately 9.525 mm, which is suitable for small and medium flow hydraulic systems and is commonly found in compact equipment or branch hydraulic pipelines.
