At some point during the design and build of new equipment, the question arises of which hydraulic hose assembly to choose. The market offers numerous options in a wide range of price points. With seemingly endless hose and fittings options, how do you select the best product for your application? Specifying the right hose In […]

Ryco hose protection devices ensure hydraulic hose safety
A resounding theme at IFPE 2017 this week has been talk about safety. With high-pressure hydraulics, one must always think about the dangers presented, particularly with hose, when fluids can escape and cause leaks and even cause a hose to burst, creating dangerous hose whip. That’s why one of the most prominent displays at Ryco […]
What is nonconductive hose?
Engineers and technicians specifying hoses for hydraulic circuits routinely consider factors like pressure ratings and flow capacity. But in some instances, electrical shock is a potential risk to equipment and operators, and that demands hydraulic hoses that ensure safety when machines operate near high-voltage sources like power lines. Thus, nonconductive hydraulic hoses are recommended for […]
How do you measure threads on a hydraulic fitting?
Before you select a hydraulic fitting, you must first determine if its threads will match the hose you have selected. Measuring and identifying the fittings is easily done but you must have the correct tools. These tools include ID/OD calipers and thread pitch gauges. Using the thread pitch gauge, as seen in Figure 1, simply […]
What is the minimum bend radius for hydraulic hose?
The minimum bend radius of hydraulic hose represents the smallest diameter that a looped hose can achieve. A hydraulic hose is constructed of three layers, each of which adds to the stiffness of the hose; the tube, the reinforcement(s) and the cover. Depending on the nature of these layers, the bend radius changes. Although tubes […]
How does extreme heat affect hydraulic hose?
In a previous posting, the editors at Fluid Power World discussed how ultra-low temperatures can play havoc with the performance of typical rubber hose. Hydraulic hose used at high temperatures faces performance issues too, but for different reasons. That’s because thermal exposure can cause aging of elastomers and plastics. (Other causes of aging include exposure […]
When should you choose tube over hydraulic hose?
Josh Cosford, Contributing Editor to Fluid Power World, weighs in on when you should choose pneumatic tubing over hydraulic hose for an application. Tube I think is for good permanent applications. Sometimes it has a higher pressure capacity. It also has a cleaner look. They last longer and they don’t fail as rapidly. It all […]
