How to Change a Hydraulic Hose Without a Swivel


Understanding the hydraulic system's functioning in heavy machinery or equipment is vital to ensure smooth operations. One essential component of this system is the hydraulic hose, responsible for transmitting fluid between various parts. Over time, these hoses may wear out or develop leaks, requiring replacement. Typically, hydraulic hoses are equipped with swivel fittings, allowing for easy installation. However, in certain situations, such as tight spaces or unavailable swivel fittings, it becomes necessary to change a hydraulic hose without a swivel. In this article, we will guide you through the step-by-step process of changing a hydraulic hose without a swivel, ensuring efficient replacement.

1. Understanding Hydraulic Hoses

Before diving into the replacement process, it's crucial to have a good understanding of hydraulic hoses and their role. Hydraulic hoses are responsible for transmitting hydraulic fluid, primarily oil, between various components in a hydraulic system. These hoses are typically reinforced with layers of synthetic materials and are designed to withstand high pressure. Depending on the specific application, hydraulic hoses may vary in size, length, and fittings. It is essential to choose the correct hydraulic hose replacement that matches the specifications of the original hose.

2. Gathering the Right Tools

To successfully change a hydraulic hose without a swivel, it is important to have the right tools readily available. Here are the tools you will need for the job:

a) Wrenches: Adjustable wrenches or open-end wrenches are necessary to loosen and tighten fittings.

b) Pipe Cutter: A pipe cutter helps cut through the old hydraulic hose to remove it from the system.

c) Tubing Cutter: In case the hydraulic hose runs inside a tube, a tubing cutter will be necessary to remove the old hose.

d) Tubing Bender (If Required): If the new hydraulic hose needs to be bent to fit specific angles, a tubing bender will help achieve precise bends.

e) Safety Glasses and Gloves: Safety should always be a priority, so wearing glasses and gloves will protect your eyes and hands from any potential injury.

3. Identifying the Correct Replacement Hose

Choosing the correct replacement hose is crucial for seamless integration into the hydraulic system. When sourcing a new hydraulic hose, ensure it matches the inside and outside diameter, pressure rating, and length of the original hose. Additionally, check if the new hose is compatible with the hydraulic fluid used in the system. Referring to the specifications mentioned in the manual or consulting a hydraulic specialist can help in identifying the right replacement hose.

4. Shutting Down and Preparing the System

Before replacing the hydraulic hose, shut down the machinery or equipment to prevent any accidents. Once the machinery is turned off, relieve pressure from the hydraulic system by activating the relevant relief valve or hydraulic controls. This step is crucial to keep hydraulic fluid from spraying out when removing the old hose. Place suitable containers or absorbent materials under potential spill points to catch any fluid that may escape during the replacement process.

5. Removing the Old Hydraulic Hose

Begin by using wrenches to loosen the fittings on both ends of the old hydraulic hose. Ensure you have a firm grip on the fittings to avoid any damage. After loosening the fittings, use a pipe or tubing cutter to remove the old hose from the hydraulic system. In case the hose is routed inside a tube, use a tubing cutter to carefully eliminate the old hose from the tube.

6. Installing the New Hydraulic Hose

Once the old hose is removed, inspect the fittings for any dirt, debris, or damage. Clean the fittings thoroughly if required. Insert one end of the new hydraulic hose into the fitting and tighten it using a wrench. Ensure the hose is inserted evenly and securely. Repeat the process for the other end of the hose, gradually tightening until it is secure.


Despite the absence of swivel fittings, changing a hydraulic hose can be achieved without much difficulty. Following the step-by-step process outlined above and having the right tools and replacement hose can make the task significantly easier. By carefully removing the old hose and installing the new one, you can maintain the hydraulic system's functionality and prevent potential leaks or malfunctions. Regular maintenance and inspection of hydraulic hoses are essential for the smooth operation and longevity of heavy machinery and equipment.
