how to attach hydraulic hoses


Hydraulic hoses are an essential component in various industries, providing a reliable means of transferring hydraulic fluid and power from one source to another. Whether you are a professional hydraulic technician or someone with a basic understanding of hydraulic systems, learning how to attach hydraulic hoses is an invaluable skill. In this article, we will delve into the step-by-step process of attaching hydraulic hoses and explore key considerations to ensure a secure and leak-free connection. So, grab your safety glasses and let's dive right into the world of hydraulic hose attachment.

Understanding Hydraulic Hoses: Basics and Types

Before we delve into the attachment process, it's crucial to have a basic understanding of hydraulic hoses and their various types. Hydraulic hoses are flexible tubes designed to carry pressurized hydraulic fluid, transmitting force within a hydraulic system. These hoses are constructed with an inner tube that transports the fluid, reinforcement layers for strength and durability, and an outer protective cover.

There are several types of hydraulic hoses available, each designed to accommodate specific applications. Some common types include:

1. Wire Braided Hoses: These hoses are constructed with multiple layers of wire reinforcement, providing excellent flexibility and strength for medium to high-pressure applications.

2. Spiral Hoses: As the name suggests, spiral hoses have a spiral-wrapped wire reinforcement, ensuring enhanced flexibility and endurance, making them suitable for heavy-duty applications.

3. Thermoplastic Hoses: These hoses are composed of thermoplastic materials, making them lightweight, flexible, and resistant to a wide range of chemicals. They are typically used in applications where high-pressure fluids are involved.

4. Specialty Hoses: There are specialized hoses available for specific applications, such as suction and return, ventilation, air conditioning, and more. These hoses are constructed with additional features to cater to their intended purposes.

Step-by-Step Guide to Attaching Hydraulic Hoses

Assembling the Necessary Tools and Equipment

Before starting the hydraulic hose attachment process, it is important to gather the necessary tools and equipment. This includes a hacksaw or hydraulic hose cut-off saw, a deburring tool or sandpaper, a hose crimper, fittings, a hydraulic hose assembly lubricant, and safety gear such as safety glasses and gloves.

Measuring and Cutting the Hydraulic Hose

Before cutting the hydraulic hose, ensure it is depressurized and the system is turned off. Measure and mark the required length on the hose, leaving room for fittings and flexibility. Utilize a hacksaw or a hydraulic hose cut-off saw to achieve a clean and square-cut end.

Removing Burrs and Cleaning the Hose

After cutting the hose, remove any sharp burrs or metal filings on both the inner and outer sides of the hose using a deburring tool or sandpaper. Ensure a smooth surface to prevent damage to the sealing surfaces during the connection process.

Selecting and Crimping the Fittings

Choosing the correct fittings is crucial for a secure and leak-free connection. Match the fitting type, size, and thread to the hydraulic hose and equipment's specifications. Apply a thin layer of hydraulic hose assembly lubricant on the inside of the fittings and crimp them onto the hose using a suitable hose crimper.

Attaching the Hydraulic Hose

Align the hose assembly with the desired connection point, ensuring that it is properly oriented. Push the hose onto the mating fitting until it seats fully. Double-check the alignment and connection for a snug fit. Repeat the process for multiple hose connections if required.


Attaching hydraulic hoses is a fundamental skill required in numerous industries, and understanding the step-by-step process is essential to ensure proper functionality and minimal chances of leakage. By following the guidelines provided in this article, you can confidently attach hydraulic hoses, allowing for efficient power transmission and optimal performance within a hydraulic system. Remember to prioritize safety, use the appropriate tools and fittings, and regularly inspect the connections to maintain a reliable hydraulic system.
