Can You Use Hydraulic Hose for LP Gas?


Hydraulic hoses are designed to withstand high pressure and transmit fluid power efficiently in hydraulic systems. They are typically used in various industries for applications that involve transmitting hydraulic fluid. However, as the demand for alternative fuel sources grows, questions arise about the compatibility of hydraulic hoses with liquefied petroleum (LP) gas. In this article, we will explore whether it is possible to use hydraulic hoses for LP gas and discuss the potential risks and considerations associated with this practice.

Understanding LP Gas:

Liquefied petroleum gas (LP gas), also known as propane or butane, is a common alternative fuel used in residential, commercial, and industrial applications. It is a highly volatile and flammable gas that is stored under pressure in tanks or cylinders. LP gas is commonly utilized for heating, cooking, and powering appliances, as well as in industrial processes.

Hydraulic Hoses and their Characteristics:

Hydraulic hoses are specifically manufactured to withstand high pressure, making them ideal for transmitting hydraulic fluids in various applications. They are constructed with several layers of rubber and reinforcement materials, such as steel wire braids or spirals, ensuring their durability and flexibility. These hoses come in different sizes, types, and pressure ratings to meet specific requirements and applications.

The Compatibility Issue: LP Gas vs. Hydraulic Hoses

When considering using hydraulic hoses for LP gas, it is crucial to understand the fundamental differences between hydraulic fluids and LP gas. Hydraulic fluids are typically oils with specific viscosities, while LP gas is a highly compressed gas that behaves differently. Due to these differences, hydraulic hoses are not specifically designed or tested for LP gas applications. Consequently, using hydraulic hoses for LP gas could pose potential risks.

Potential Risks and Considerations

1. Elasticity: Unlike hydraulic fluids, LP gas is compressed as a gas and lacks the lubricating properties of hydraulic fluids. This difference could affect the elasticity and strength of hydraulic hoses if used for LP gas applications over time.

2. Leakage and Fire Hazards: LP gas is highly flammable, making leakages a significant risk. Hydraulic hoses may not be engineered to handle the quick gas expansion associated with LP gas leaks, potentially leading to hose failure and increased fire hazards.

3. Hose Material Compatibility: Hydraulic hoses are primarily constructed with rubber materials, which may not be compatible with LP gas. Propane, for example, can cause degradation of certain rubber compounds, leading to premature hose failures.

Standards and Regulations

To ensure safety and avoid potential hazards, it is essential to consider the relevant standards and regulations associated with LP gas applications. Organizations such as the National Fire Protection Association (NFPA), American Society of Mechanical Engineers (ASME), and the Occupational Safety and Health Administration (OSHA) provide guidelines specific to LP gas installations and usage. These standards often recommend using specific materials and equipment specifically designed for LP gas applications, emphasizing the importance of not repurposing hydraulic hoses for LP gas.

Choosing the Right Hose Material

If there is a requirement to transport LP gas, it is crucial to use hoses specifically designed and tested for this purpose. Hoses constructed with materials compatible with LP gas, such as thermoplastic or stainless steel, should be used to ensure safety and reliability. These materials offer better resistance to the flammable and corrosive nature of LP gas, minimizing the risk of hose failure and leakage.

Ensuring Safety and Proper Usage

To prioritize safety when working with LP gas, it is essential to:

1. Consult Experts: Seek advice from knowledgeable professionals in LP gas installations and equipment to ensure compliance with relevant safety codes and regulations.

2. Follow Manufacturer Recommendations: When sourcing hoses and fittings, adhere to the manufacturer's recommendations and guidelines for LP gas usage.

3. Regular Inspection: Implement a regular inspection and maintenance program to detect any potential hose degradation or wear, ensuring early replacement when necessary.

4. Education and Training: Provide proper education and training for individuals handling LP gas to understand the risks associated with it and the importance of using appropriate equipment.


While hydraulic hoses are not designed for LP gas applications, it is crucial to prioritize safety and adhere to proper regulations and guidelines. Using hoses specifically designed for LP gas ensures the integrity and reliability of the system, minimizing the risk of accidents and hazards associated with incorrect hose selection. Therefore, it is not recommended to repurpose hydraulic hoses for LP gas; instead, opt for hoses specifically designed and tested for this particular application.
