By Josh Cosford, Contributing Editor Hydraulic hoses are stressed in two directions — bending and rotating. Hose is designed with reinforced steel spirals or mesh weave, making it perfect for bending, even while internal force exerts stress upon the hose. Torque, on the other hand, makes friends with no hydraulic hose. If you’ve ever tried […]

Fittings and adapters used in fluid power are manufactured using various materials selected by designers to suit the specific needs of the […]

By Josh Cosford, Contributing Editor There are three ways to plumb a hydraulic system — rigid systems, flexible systems or a combination of the two. Rigid systems include pipe and various forms of tube, while flexible systems are assembled using only hydraulic hose. Most machines today are created using a combination of fixed plumbing, where […]

Contributed by Gary Molton • BSc, Owner, Engineering Adventures Poor assembly or using the wrong type of fluid power fitting has been shown to increase risk of fluid leakage and industrial injury. Fitting designs have changed considerably over the last 30 years to reduce these risks but this has resulted in a myriad of assembly […]

They have a maximum pressure rating of 300 psi and can withstand temperatures up to 175℉. Numerous fitting styles have been added, including male straight fittings, male elbows, branch tees, union straight fittings, union […]

By Josh Cosford, Contributing Editor When installing hydraulic hose assemblies, if tight is good, then tighter is better, right? To be sure a hydraulic hose never accidentally loosens during operation, should we get the biggest pry bar we can find to help lock that hose fitting in for good? Not precisely — torquing your hose […]

Will hydraulics ever get past the leakage issue? I’ve heard people discuss this question countless times over the three decades that I’ve worked in and written about the technology. Time and time again, people bash this useful technology because of perceived problems with leakage. I have encountered this negative talk on factory floors, in educational…

By Joe Carr, product manager, specialty fittings, Brennan Industries, Inc. In the pursuit of industrial progress, companies are seeking innovation that extends to inconspicuous components like hydraulic fittings and flanges. Operating discreetly in the background, these parts take a crucial role in propelling industries forward. Hydraulic components are essential to machinery, directing high-pressure fluid flows […]

By Josh Cosford, Contributing Editor Air hoses are vital for many pneumatics-heavy industries, serving as lifelines transporting air to power machinery and tools. However, leakage is a common and frustrating issue that often arises in many pneumatic distribution systems. Leaks hinder efficiency and lead to unnecessary energy wastage and increased operational costs. Thankfully, preventing pneumatic […]

If you stopped by the Brennan Industries booth at IFPE 2023, you might have had the same chance I did — to meet Perry Detton, founder of Hose Box. Hose Box has brought to market a series of Emergency Hydraulic Repair Solutions. Hose Box products are targeted for use by end users, such as construction […]

The integration provides the expansion of product offerings for Sun’s longstanding sales distribution channels around the globe. The Sun offerings will include O-ring Face Seal (ORFS), British Standard Parallel Pipe (BSPP), and Joint Industry […]

By Josh Cosford, Contributing Editor Some objects are universal by their very nature, mattering not where you reside or if you’re part of a colonial legacy. No matter where you travel, a wheel is a wheel because it’s so absolutely perfect for the job that it leaves any other method of moving heavy objects obsolete. […]

JW Winco continues to expand its selection of standard parts of AISI 316L (A4) stainless steel — now including threaded plugs, magnetic plugs, and robust oil sight glasses for hydraulics in an entirely new design.

Stauff’s new series is the consistent further development of their existing QRC-FT coupling series, which has proven itself in the market for more than 10 […]

By Josh Cosford, Contributing Editor There isn’t much in the fluid power world taking a unique spin on a familiar concept. Pumps, valves and actuators operate and look much the same as decades ago, especially if you ignore electronic advancements. Hydraulic components like the internal gear pump and electrohydraulic actuator are certainly worth your time […]

By Josh Cosford, Contributing Editor No matter how malevolent, some objects of desire seem to allure us despite our righteous awareness – diesel engines, plastic bags, Tik Tok. Indeed, we like to think that we always choose what’s best for our conscience when offered a choice, assuming we have one. Unfortunately, sometimes we indulge in […]

By Josh Cosford, Contributing Editor Hydraulic quick couplings provide users with the ability to rapidly connect and disconnect hydraulic hoses to machines or other sections of plumbing. Also called quick-connects or quick disconnects, these fittings allow fluid to flow when the male and female sides are locked together. Conversely, when disconnected, the quick couplings prevent […]
