What kind of high-pressure hose is needed for a compressor

In order to optimize the efficiency of utilizing high-pressure air compression and transportation equipment, it is crucial to make a wise selection of a compressor hose (or simply a hose). Despite the seemingly straightforward nature of this task, it is essential to have a good understanding of the various types and technical specifications of this component, as they are directly tied to its intended field of application.

Purpose and characteristics of the compressor hose

Compressor hoses are specifically engineered for conveying a pressurized stream of air to the pneumatic device or other equipment that is connected. This may include an airbrush, gun, grinder, drill, and much more.

Attention! Generally, hoses are not included with pneumatic equipment and compressors, so they need to be bought separately.

To ensure the purchase of the appropriate model, it is important to consider the specific needs of the tool that requires connection. The choice of hose type (straight, twisted, etc.) as well as its technical specifications (such as material, length, diameter, connections, and pressure limit) should be determined according to the specific operating conditions.

Types of hoses

There are several ways to classify hoses, but one of the most common methods is by their shape. Compressor hoses, for example, can be found in different shapes such as straight, twisted spiral, and in coils.

Straight hose

One of the benefits of using straight compressor hoses is their ability to provide high flow capacity due to their large diameter. These hoses are highly recommended for applications that require impressive outlet pressure. Additionally, they are reinforced with high-quality materials and are not susceptible to damage from extreme temperatures. Straight hoses are commonly purchased for industrial use and production purposes.

Twisted spiral hose

Twisted spiral compressor hoses find frequent application in automotive workshops, particularly when pneumatic tools such as pumps, wrenches, and drills are extensively used. What makes them unique is their ability to maintain a coiled shape, even when not secured. This allows for compact storage, making them a perfect fit for small workspaces. Additionally, there is no need for constant assembly and stowing, as the hose automatically reverts to its coiled position after use.

Important! It is worth noting that twisted hoses generally have smaller diameters and lower flow capacity compared to straight hoses.

Coiled hoses

These hoses, which come in coil form, are specifically designed for organizing long overhead lines. In comparison to spiral hoses, they offer enhanced strength and reliability, allowing them to handle higher pressure. However, it’s important to note that they are heavier and not as user-friendly.

Choosing the right hose

When purchasing the ideal hose for your air compressor, it is crucial to consider various factors such as the length and material of the product, the permissible pressure and shape, as well as the type of connection and other unique characteristics.

Length

When choosing a hose, it’s crucial to correctly determine the appropriate length. If this calculation is done inaccurately, it can result in a loss of pressure, whether it’s minor or significant, depending on the severity of the mistake. The calculation should be based on the capacity of the compressor: the higher the capacity, the longer the hose length that is permissible.

Pro Tip! It’s advisable to purchase a hose that’s specifically designed for a particular compressor model. This will help prevent any mistakes and take into consideration not only the length but also other characteristics.

It’s important to keep in mind that the hose should not be overly stretched during usage. Therefore, it’s necessary to select a hose that’s slightly longer than required. The standard hose lengths available are 6, 8, 12, or 15 meters.

Diameter

This parameter determines the capacity of the hose – the greater the value, the more air the compression equipment will pump within the designated time frame. It is especially crucial to accurately calculate this parameter for specialized pneumatic tools, as they require intense air pumping in short intervals. Therefore, a larger inner diameter is more suitable for such tasks. However, even hoses with smaller diameters remain popular, despite their lower efficiency. Thin spiral hoses are chosen when their allowable pressure meets the requirements of the available pneumatic equipment, allowing users to save a certain amount of money.

Important! The wall thickness is another significant characteristic of the hose. The higher the thickness, the more pressure the hose can withstand.

In general, spiral hoses typically measure 6 mm in inner diameter and 8 mm in outer diameter. Occasionally, there are also variations with diameters of 8 and 10 mm, but these are more commonly utilized for specialized tasks with narrower focuses.

Material

1. PVC hoses, also known as polyvinyl chloride hoses, offer affordable pricing and satisfactory performance characteristics. One of their notable advantages is their lightweight nature. However, it is important to note that these products should not be exposed to physical abuse and are not suitable for use in outdoor heated areas.
2. Rubber hoses, also referred to as classic oxygen hoses, are highly durable and resistant to mechanical stress. They can withstand high temperatures, making them suitable for use in various thermal conditions. A drawback of rubber hoses is their heavy weight and inconvenient transportation.
3. Polyamide sleeves are inexpensive, but they are not designed for prolonged use. They tend to quickly wear out and deform when bent or fractured, which can lead to air leakage.
4. Polyurethane hoses exhibit the most favorable combination of operational characteristics. They possess elasticity, resistance to wear, and are not susceptible to bending or low temperature conditions. These hoses are ideal for connecting pneumatic tools.
5. Reinforced hoses are a composite material consisting of rubber and polyurethane, reinforced with synthetic threads for enhanced strength. These products are highly resistant to impacts, over-crimping, and even deformation caused by heavy objects. Their main drawbacks include their weight and cost. Reinforced hoses are primarily used for air line installations and are popular in industrial and manufacturing settings.
6. Silicone hoses are rarely employed for connecting air tools or compressors. They are designed to operate under low pressure conditions and can withstand minor temperature variations. However, these hoses are lightweight and flexible. Silicone hoses are commonly utilized for aquarium applications.

Connections

To establish a connection for the hose, herringbone fittings are employed, carefully chosen to correspond to the internal diameter of the hose (typically 6, 8, or 9 mm). For hoses with a spiral design, fittings with screw-in connections featuring 1/4" and 3/8" diameters are utilized. In either situation, a socket is inserted and secured with a clamp on top to ensure optimal durability.

After that, the prepared hose is attached to the compressor using a rapid coupling that includes a check valve. Its main benefit is that air supply only occurs when the connector is connected. If it is pulled out, the valve is activated and no air escapes. Another advantage of this connection is the ability to quickly connect multiple tools to the compressor one after another, using hoses with connectors that have the same diameter as the coupling. These connections are commonly referred to as quick couplings or "quick disconnects".

By the way! Specialized stores offer special sets of quick couplers that include a rapid coupling and multiple couplings.

Aside from the quick coupler, another commonly used connection is the bayonet connection. What sets it apart is that one of the parts to be connected has a set of pins or projections on its outer surface, while the other part has matching cutouts of the same size. When these parts are joined together, the protrusions fit into the corresponding notches, and then they can be rotated to secure the attachment. This method also enables easy disconnection and connection of hoses to the compressor. However, it should be noted that this solution is now considered outdated and is slowly becoming less common.

Permissible working pressure

This is the key factor to consider when choosing a hose for compression equipment. The preferred working pressure range is 6-8 bar, although high-pressure hoses (HP) can handle up to 10 bar, it is rarely necessary.

Note! If the pressure limit of the hose does not match the equipment’s requirements, the hose material will deteriorate rapidly and eventually burst at its weakest point. This can lead to serious consequences, including injury to the user.

Despite the fact that manufacturers incorporate a specific safety margin in each hose (usually ranging from 2.5 to 1 and up to 4 to 1), continuous operation under elevated loads undermines the durability of any hose, particularly one operating under pressure. For instance, when utilizing an oxygen autocompressor, the pressure regulator may be adjusted to its utmost setting, causing the hose to endure a constant maximum load. This aspect should be considered when choosing the appropriate hose, as neglecting it may result in a significantly reduced lifespan.

Scope of application

The range of applications for hoses depends on the material they are made of and their shape. Straight rubber and PVC hoses are typically used to connect air lines from compression equipment to the workplace. On the other hand, spiral-shaped polyurethane or polyamide hoses are commonly used to connect pneumatic tools to compression equipment. It is worth noting, however, that these categorizations are not strict rules, as hoses can be used for various other purposes as well.
