● Insert Fittings

Alignment Technique: Align the fitting with the hose carefully. Some professionals recommend marking the insertion depth on the hose with a marker as a guide.

Insertion Depth: The fitting should be inserted into the hose up to the marked depth or as specified by the manufacturer. Too shallow or too deep can result in a poor connection.

Lubrication (Optional): In some cases, a lubricant may be used to ease the insertion. However, make sure the lubricant is compatible with the hydraulic fluid in the system.

● Tightening Procedure

Use of Wrenches: Once the fitting is inserted, use the appropriate wrench to tighten it. Hold the hose in one hand and use the wrench in the other to secure the fitting.

Torque Specifications: It’s crucial to apply the correct amount of force when tightening. Over-tightening can strip the threads, while under-tightening can result in leaks. Always refer to the manufacturer’s torque specifications for guidance.

Test Stages

● Pressure Test

Recommended Pressure Level: Conduct a pressure test at the level recommended by the manufacturer. This ensures the fitting can withstand the system’s operational pressure.

Duration of Test: Run the test for a sufficient amount of time to be confident in the fitting’s integrity. A typical test might last around 5 to 10 minutes.

● Visual Inspection

Leak Check: After the pressure test, visually inspect the connection for any signs of leakage. If you spot a leak, you may need to re-tighten or replace the fitting.

Calibration Verification: Finally, ensure that the fitting is properly calibrated. This is especially important for systems that require precise fluid control.

Safety Measures During Installation

● Personal Protective Equipment

Gloves: Safety starts with your hands. Always wear gloves to protect against sharp edges, hot surfaces, and hydraulic fluid.

Goggles: Your eyes are just as vulnerable during the installation process. Wearing safety goggles protects against flying debris, splashes of hydraulic fluid, and other potential hazards.
