When should you use offline filtration systems?
Editor's note: This article was updated with links and additional text on February 6, 2025. By Josh Cosford, Contributing Editor Sometimes, inline hydraulic filters are not enough to keep a hydraulic system happy. Most hydraulic systems are installed with at least a return filter, which semi-purifies fluid before it is once again welcomed … [Read more...] about When should you use offline filtration systems?
Is chemical analysis all I need to maintain my hydraulic fluid?
Often, users of hydraulic fluid will confuse a chemical analysis with a complete fluid analysis, which provides particle count of contaminants, amounts of water, and more. Oil samples that are sent off to a lab without specific instructions will return with valuable data but not all the data points you require. In most cases, the majority of labs … [Read more...] about Is chemical analysis all I need to maintain my hydraulic fluid?
What makes a seal for hydraulics different from a seal for pneumatics?
The first issue when talking about pneumatics vs. hydraulics is always going to be severity of the duty. Obviously, the durometer of the seal is very important. When you get into a 70, 80, or 90 durometer seal, it becomes very resistant to being smushed. As the pressure increases to, say, 3,000, 4,000, 5,000—maybe even 10,000 psi or more, it just … [Read more...] about What makes a seal for hydraulics different from a seal for pneumatics?
What if I have an old cylinder that I can’t get seals for anymore?
Ages ago, you might have had some cylinders that had V-Packings, and you could screw tight on the washer to kind of make them fill up the space again—but they had high leakage, not to mention high maintenance, and they’re just a pain. If you can source those, the best thing to do is have a good relationship with your hydraulic distributor and … [Read more...] about What if I have an old cylinder that I can’t get seals for anymore?
Can any seal be used in a cylinder if it’s about the same shape?
The shape of a seal is certainly an important aspect. For example, if you have a U-cup seal in a piston, you want to use U-cup seals as well unless the customer’s specifying that you change it—but you may have to change the piston in that case as well. The shape is important. In those kinds of occasions, seals can be interchangeable but the other … [Read more...] about Can any seal be used in a cylinder if it’s about the same shape?
