2C9、2D9 Reducer Tube Adaptor With Swivel Nut 90°Elbow Fittings

The 90° elbow design of these fittings is carefully crafted to minimize turbulence and pressure loss during fluid flow. The smooth curvature of the bend allows fluids to change direction without significant disruption, maintaining the integrity of the flow. This is particularly important in high - pressure or high - flow applications, where any turbulence could lead to inefficiencies, increased wear on components, or even system failures. Whether it's a hydraulic system in an industrial machine or a pneumatic system in a factory, the well - designed 90° bend ensures that fluids can be routed as required with minimal energy loss.

One end of the adaptor features a metric male thread, which adheres to the DIN 2353 standard. This male end can be securely fastened to a corresponding female - threaded port on a pipe or other fittings, providing a stable and leak - tight connection. The other end is a swivel metric female connection with a swivel nut. The swivel design offers remarkable flexibility during installation. It enables the fitting to be adjusted to the desired angle without having to re - position the entire piping system. This is extremely useful in tight or complex spaces where aligning components can be challenging. The swivel nut, when tightened, compresses the appropriate sealing elements (such as sleeves or gaskets), creating a reliable seal that prevents any fluid leakage.

The 2C9 and 2D9 reducer tube adaptors with swivel nut 90° elbow fittings are designed to handle high - pressure fluid systems. The 2D9 heavy - duty fittings are engineered to withstand extremely high pressures, making them suitable for industrial applications such as hydraulic presses, oil and gas pipelines, and high - pressure water systems. They can endure pressures up to 6000 psi (pounds per square inch), ensuring reliable performance in demanding environments. The 2C9 light - duty fittings, while having a lower pressure rating compared to the 2D9, can still handle pressures up to 4000 psi, making them suitable for a wide range of applications where moderate pressures are involved. Their robust construction and high - quality materials enable them to maintain their structural integrity and sealing performance under high - pressure conditions, ensuring the safe and efficient operation of the fluid transfer system.

The combination of the swivel nut design and proper installation techniques results in a highly reliable leak - proof seal. When the swivel nut is tightened, it compresses the sleeve or gasket (depending on the specific design) against the pipe, creating a tight and secure seal. This multi - layer sealing mechanism effectively prevents any fluid leakage, even in systems with high - pressure differentials or in applications where the fluid is highly volatile. In hydraulic systems, where the leakage of hydraulic fluid can lead to reduced efficiency, equipment damage, and safety hazards, the leak - proof performance of these fittings is crucial. In chemical plants, where the leakage of hazardous chemicals could have severe environmental and safety consequences, the reliable sealing of the 2C9 and 2D9 fittings provides peace of mind and ensures compliance with safety regulations.

• Simple Operation: During installation, you just need to insert the pipe into the ferrule fitting and tighten the nut with a wrench. There is no need for complex operations such as welding or flaring, which can save a great deal of installation time and labor costs.

• No Special Tools Required: Generally, only commonly used tools like wrenches are needed to complete the installation. Unlike some other fittings that require specialized welding equipment or flaring tools, this reduces the installation threshold and equipment requirements.

• Good Sealing Performance: When the nut is tightened, the ferrule will deform and firmly grip the pipe, forming multiple sealing barriers. This can effectively prevent the leakage of hydraulic oil and ensure the sealing and stability of the hydraulic system.

• Strong Vibration Resistance: During the operation of the hydraulic system, even in the presence of vibrations and impacts, the clamping force between the ferrule and the pipe can ensure that the connection will not loosen, maintaining the normal operation of the system.

• Suitable for Multiple Pipe Materials: It can be connected to pipes made of various materials such as steel pipes, copper pipes, and stainless - steel pipes, meeting the requirements of different hydraulic systems for pipe materials with a wide range of applications.

• Multiple Pressure Ratings Available: There are products of different specifications and pressure ratings for selection. They can adapt to various hydraulic systems ranging from low pressure to high pressure, meeting the usage requirements under different working conditions.

• Easy Disassembly: When it is necessary to repair or replace components, simply loosen the nut, and the ferrule fitting can be removed from the pipe without causing damage to either the pipe or the fitting, which facilitates subsequent repair and replacement work.

• Reusable: After the ferrule fitting is disassembled, if components such as the ferrule and nut are not damaged, they can be used again, reducing the maintenance cost.

• Aesthetically Pleasing After Installation: Compared with connection methods such as welding, the ferrule fitting presents a neater and more aesthetically pleasing appearance after installation. There will be no traces like welding scars left behind, making the overall layout of the hydraulic system more regular.

The hydraulic ferrule fitting is a commonly used connecting component in hydraulic systems and has a wide range of applications, mainly reflected in the following fields:
