By Josh Cosford, Contributing Editor Hydraulic hoses come in many sizes and designs, and the expression of each design is a result of the purpose of that hose. Generally, there are three common locations where a hose is used in a hydraulic system: suction lines, working lines and return lines. Each location has its own […]

A primer on hydraulic hose bend radius
By Josh Cosford, Contributing Editor Hydraulic hose bend radius, quite simply, describes how tightly circular a hydraulic hose can bend. More importantly, designers and technicians wish to know the minimum bend radius a hose handles while maintaining integrity. Although one might easily force a hose into a tight radius during installation, its design and construction […]
How long should a hose last (and tips to extend service life)
By Josh Cosford, Contributing Editor How long a hydraulic hose should last depends on many factors, not the least of which is who you ask. Some standards want to see hoses changed every few years, yet others are okay up to ten years (such as with the SAE). But do we even need to apply […]
MegaSys MXG 5K hydraulic hose is light-weight, flexible and durable
Gates has introduced its latest breakthrough hydraulic hose, the MegaSys MXG 5K, which is lighter, more flexible and more durable than a typical 5,000 psi (350 bar) hydraulic hose. “Our ongoing commitment to research and development has resulted in another world-first innovation from Gates. MXG 5K sets a new standard for hydraulic hose,” said Mike […]
How do you overcome hydraulic hose maintenance challenges?
By Josh Cosford, Contributing Editor Most consider a hydraulic hose to be maintenance-free. They’re often installed and forgotten until they need replacement, hopefully not under conditions of catastrophic failure. Contrary to popular belief, hydraulic hose does not enjoy infinite service life. Like any component manufactured from metal and rubber, you may undoubtedly expect failure in […]
What is skiving, and when should you use it on your hose assemblies?
By Josh Cosford, Contributing Editor Skiving is removing the outer cover at the end of a hydraulic hose in the location of the crimp fitting. For some high-pressure applications, the hose’s inner tube ID may be skived to allow the hosetail to better fit. Using a specialized machine with externally rotating mandrels, the tooling cuts […]
USCG-accepted high-temperature hose for medium and high-pressures
Kurt Hydraulics introduces two new lines of US Coast Guard (USCG) accepted high temperature hose. Kurt High Temp Hydraulic Hose (SAE R16 DIN EN 853) — Recommended for high pressure, high temperature hydraulic oil lines, this Kurt hose handles both high pressure, high temperature applications. It is SAEJ1942 USCG accepted hydraulic only. It features two […]
Gates launches MegaSys MXG 4K hydraulic hose for drop-in replacement
Gates is redefining high-pressure hydraulic performance with the introduction of the MegaSys MXG 4K hydraulic hose. Qualified to one million impulse cycles, this hose is a lightweight, compact, highly flexible drop-in replacement for conventional spiral hoses. Gates XtraTuff Plus cover, a standard upgrade on MXG 4K, offers improved abrasion and ozone resistance, providing improved durability […]
High-temperature hydraulic hoses
Temp Tech High Temperature hydraulic hoses by Alfagomma withstand long exposure to nearly every type of hydraulic fluid, lubricating oil or fuel commonly used in industry today, including fire-resistant hydraulic fluids. Available in single wire braid versions 1SN/R1AT and 100R5, and double wire braid 2SN/R2AT, Temp Tech hoses will operate in applications with continuous high […]
High-tensile hydraulic hose for grappling applications
Manuli Hydraulics announces the launch of its new HydroRope range of premium hydraulic hoses for grappling applications. When selecting a hydraulic hose for most normal applications, the tensile strength of the hose is not usually a critical determining factor. However, in certain specialist applications, such as the hydraulic grabs used in diaphragm wall building operations, […]
