Hydraulic pipe fittings

Hydraulic pipe fittings are a crucial component within hydraulic systems. They serve to connect, control, direct, divide, seal, and support hydraulic piping systems, ensuring the smooth operation of the entire hydraulic system. These fittings play a pivotal role in complex hydraulic systems, especially in large-scale equipment that requires the accomplishment of multiple functions. Hydraulic pipe fittings encompass various types, such as elbows, couplings, and reducers. Elbows alter the direction of piping, typically available in angles like 45 degrees and 90 degrees to accommodate different installation requirements. Couplings are used to join two pipes together, serving as a common accessory in industrial piping connections. Reducers, on the other hand, change the diameter of piping to meet varying flow and pressure needs. Additionally, hydraulic pipe fittings include various types of connectors, such as hydraulic connectors and quick-disconnect couplings. These connectors feature different structures and functions, capable of fulfilling various complex hydraulic connection requirements. For instance, hydraulic connectors are commonly used in high-pressure hydraulic systems, exhibiting excellent sealing performance and stability. Quick-disconnect couplings allow for the rapid connection and disconnection of hydraulic piping, enhancing the operational efficiency and safety of equipment. In summary, hydraulic pipe fittings are indispensable components of hydraulic systems, with their quality and performance directly impacting the stability and reliability of the entire system. Therefore, when selecting and using hydraulic pipe fittings, it is essential to consider factors such as material, structure, sealing performance, and application scenarios to ensure the smooth operation and long-term stability of the hydraulic system.

Installation Instructions

For proper assembly following assembly instruction shall be followed. Improper assembly may lead to malfunctions or impair safety.

Assembly in fittingbody

1. Cut the tube：

1/2˚ angle tolerance to the tube axis is permissible. Tube cutter is not recommendable.

2. Lightly remove chips and particles from the inside and outside cut edges of tube. Bevel up to 0.2mm × 45˚ is permissible.

3. For tube bend, the minimum height from the straight pipe end to the bending radius must be at least twice the height of the nut.

4. Lubricate thread and cone of the fitting body, ring and thread of nut.

Assembly

5. Slip nut and then ring onto the tube end. Ensure that the ring is placed correctly.

6. Screw nut manually onto fitting body until finger tight. Hold the tube against the shoulder in the cone of the fitting body.

7. Mark nut and tube for measuring the prescribed turns of the nut.

8. Tighten the nut 1 1/4 turns. Tube must not turn with tube. Stop edge of the ring limits over-tightening by increasing tightening torque.

Check & Final Assembly

9. Loosen nut and remove ring-mounted tube from fitting. And check if a visivle collar has formed on the pipe in front of the first cutting edge. If not, tighten slightly more.

10. Insert the pre-assembled tube into the fitting.

While holding fitting body with a wrench, tighten nut approx. 1/4 revolution beyond the point of a clearly perceptible resistance.
