When choosing hydraulic hoses, you’ll want to look for a few features. Three-layer construction, Chemical compatibility, Durability, and Inspection are all important considerations. We’ll talk about each of these features in more detail later in this article. But first, let’s talk about what couplings are. What are the differences between these types of couplings? So, go now to read on about the three most common types and why they’re important.
Three-layer construction
When designing hydraulic hoses, you should look at their three-layer construction. This reinforcement protects the inner tube from wear and tear while ensuring consistency in flow of the fluid. An outer cover is applied to protect it from weather and chemicals. The reinforcement layer is typically braided or woven into the outer hose. The reinforcement layer also protects the hose from tears and abrasion.
Modern hydraulic hoses typically have three layers: an inner tube that transports fluid, a reinforcement layer, and a protective covering. Common inner tube materials are synthetic rubber, thermoplastics, or textile yarn. The reinforcement layer protects the inner tube from abrasion and elements.
In order to ensure reliability, a hose must be constructed with multiple layers. This reinforcement is necessary to keep it flexible while ensuring that it’s not too hard to break. In addition, hydraulic hoses must resist extreme temperature fluctuations. SAE J517 is the standard for hydraulic hoses, which sets specifications for dimensional, efficiency, and durability. A typical hydraulic hose has three layers: an inner tube, a reinforcing center layer, and a protective outer layer.
The third layer should be waterproof, but there’s no guarantee. However, the cover of hydraulic hoses should protect metal wires from corrosion and UV rays. These conditions can significantly shorten the hose’s service life. Fortunately, there are many materials available to protect the internal structure from external heat.
Chemical compatibility
The chemical compatibility of hydraulic hoses depends on many factors. These include pressure, ambient temperature, and any special requirements. You must also be aware of legal regulations. If the fluid is petroleum-based, check the compatibility chart to ensure the hose is safe for your application.
The chemical compatibility chart provides a general guide for selecting hydraulic hoses. The table lists common chemicals that may interact with a hydraulic hose, as well as the corresponding hose and fitting materials. In general, petroleum-based hydraulic oil is compatible with rubber and nitrile. However, phosphate-ester-compatible hydraulic hoses require special attention to the chemical compatibility of the inner tube and the outer cover.
Chemical compatibility is essential to avoid any kind of chemical reaction between the hose and hydraulic fluid. This can cause a release of fluids into the air and can be dangerous for the operator. Incorrect use of a compatibility chart can lead to serious injuries and death.
The operating temperature of a hydraulic hose should be within the manufacturer’s recommended range. If you exceed this temperature, the hose may break down into harmful by-products that can damage the elastomers and other materials. If you are not sure of the operating temperature, consult with the manufacturer. The best way to avoid such problems is to read the manufacturer’s specifications and follow their recommendations. Then, select a suitable hydraulic hose for your needs.
Depending on the use, SAE 100R16 hoses should be used with water or petroleum-based hydraulic fluids. You should avoid using SAE 100R14 hydraulic hoses when the fluid is extremely hot or very cold. For the temperature range, you can use Type B hydraulic hoses. They feature an inner synthetic rubber tube and a steel wire reinforcement. Depending on the chemical, you should also check the temperature range.
Durability
In addition to continuous exposure to sunlight, hydraulic hoses often come into contact with other equipment parts and environmental hazards. Over time, these corrosive substances may erode the hose’s cover, leading to corrosion. Further, they may also cause reinforcement layers to fail. In forestry, for instance, hoses regularly brush against trees and logs. This can damage the hose and cause a leak.
The general operating temperature of a hydraulic system plays an important role in determining the hose’s durability. A properly-selected hydraulic hose will be able to withstand the pressure without cracking. However, even a well-selected hose can deteriorate over time if not regularly checked. Hydraulic hoses consist of a rubber cover covered by metal wires for reinforcement, and a separate rubber tube through which hydraulic fluid flows.
Follow manufacturer guidelines for proper oil selection. This is a key factor in maintaining hydraulic hoses. It’s always a good idea to use hydraulic hoses with a minimum shelf life.

Inspection
There are two main types of inspection of hydraulic hoses: visual and physical. Visual inspection is important because it allows for identification of cracks and leaks in the hose. Physical inspection involves tightening hose fittings and visual inspection is used to look for visible damage. The leak detection is the most important aspect of the inspection process. A leak can be extremely dangerous, and an expert can identify it in minutes. Experts also use leak detection equipment to reduce the overall cost of repairs, and the risk of injury to personnel and equipment.
Regular inspection of hydraulic hoses is crucial for safety and performance. Leaks in the hose can be extremely dangerous, causing serious damage if not repaired. Many companies fail to perform a regular inspection, leading to disastrous consequences. Not only can hydraulic oil cause slip and trip hazards, but it can also get injected into the body if it ruptures. Performing regular inspections can prevent costly repairs. You can also follow a schedule of regular inspections to determine if they need replacement or repair.
Another vital aspect of hydraulic hose inspection is the condition of the outer covering. Hoses can suffer damage anywhere along their length. Tight bend radii can be stressful on hose materials. And if you’re not comfortable with visual inspection, you can opt for the more advanced methods.
For best results, you should inspect hoses on a daily basis. Do not attempt to repair or reuse them. Instead, document their lifecycle. You’ll be glad you did. So, do not put off this crucial step! So, take advantage of PTS to ensure that your hoses remain in great condition.
