By Josh Cosford, Contributing Editor Particle contamination is the proverbial lord of the contamination cartel. Particles get all the attention in this world, and rightfully so. Particle contamination-related failures likely outpace water, varnish and heat combined (yes, heat is a form of contamination). It would come as no surprise, then, that … [Read more...] about Hydraulic oil analysis part 3 — measuring and controlling particle contamination

The importance of hydraulic reservoir filtration systems
By Josh Cosford, Contributing Editor If you've ever been (un)lucky enough to open up a 30-year-old hydraulic reservoir, you know how shockingly grimy they can be. I've seen 3 in. of sludge, filings and particles sedimentate enough to clog the suction filter. That hydraulic power unit had a return filter in addition to its clearly unhelpful … [Read more...] about The importance of hydraulic reservoir filtration systems
Do special hydraulic fluids require special filters?
By Josh Cosford, Contributing Editor Hydraulic systems play a critical role in various industries, powering heavy machinery and equipment with precision and efficiency. The performance and longevity of these systems heavily rely on the cleanliness and quality of the hydraulic fluid. Contamination in hydraulic fluid can cause significant damage … [Read more...] about Do special hydraulic fluids require special filters?
How to ensure hydraulic fluid cleanliness outside of filtration
Hydraulic fluid cleanliness is crucial for hydraulic systems' reliable operation and longevity. However, while filtration is critical in keeping hydraulic fluid clean, it is not the only factor that impacts fluid cleanliness. This article will discuss some tips to ensure hydraulic fluid cleanliness aside from the obvious filtration … [Read more...] about How to ensure hydraulic fluid cleanliness outside of filtration
What is the best cylinder piston seal?
By Josh Cosford, Contributing Editor How long is a piece of string? So what? Did you think you'd get a straight answer on a subject like "what is the best cylinder piston seal?" There is no best piston seal, just like there is no best car (it's the Mazda Miata, by the way). If you're in the snow belt with five kids, your best car is a … [Read more...] about What is the best cylinder piston seal?
What to consider when using TPU for fluid power seals
Contributed by Chuck White, Director of Sales & Marketing, Hallite Thermoplastic Polyurethane (TPU) is widely used in fluid power seal applications and is a family of polymers formed using a combination of isocyanate and polyol crosslinked to create a homogeneous compound polymer. There are many different combinations of these chemicals that … [Read more...] about What to consider when using TPU for fluid power seals
When are EPDM seals appropriate in hydraulic systems?
EPDM rubber is a synthetic polymer used in fluid power applications to seal static applications, such as pump housing seals or cylinder barrel end seals. Although rarely used as a dynamic seal for hydraulic applications, EPDM has benefits making it perfect for various applications. EPDM stands for ethylene propylene diene monomer and offers a … [Read more...] about When are EPDM seals appropriate in hydraulic systems?
Four tips to manage a sealing product shortage
By Corey Holloway • Sales Manager, anyseals North America The painful reality is that supply chain challenges are the new normal. Unfortunately, current world conditions have resulted in unavoidable shortages and unforeseen delays in the global availability of all manner of supplies, and there is no clear solution in view. Nevertheless, … [Read more...] about Four tips to manage a sealing product shortage
When are vacuum dehydrators necessary?
You might be surprised to hear that oil and water do mix. Of course, they won't mix when poured together in a glass and stirred with a spoon. But forces at play to destroy your hydraulic system find ways to allow much more water to saturate and emulsify with your innocent hydraulic oil. Heat, oxidation and chemical contamination increase the … [Read more...] about When are vacuum dehydrators necessary?
When should you use NBR for fluid power seals?
NBR is an acronym for nitrile butadiene rubber but goes by many other names, such as nitrile or buna. NBR is a synthetic rubber compound made from acrylonitrile and butadiene. Buna is renowned for its natural resistance to oils, fuels, water and many other chemicals. You may use NBR for most hydraulic applications, especially those within the … [Read more...] about When should you use NBR for fluid power seals?
