When should you use thermoplastic hoses?
By Josh Cosford, Contributing Editor Thermoplastics are polymers with a unique capacity to become soft, pliable and moldable when heated while solidifying upon cooling. The moldability range lies between its glass transition temperature* and its melting point, so it’s essential to avoid overheating the material. Popular techniques such as injection molding and extrusion produce many […]
What is skiving, and when should you use it on your hose assemblies?
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 and then peels the outer […]
What measurements are required for hose assembly sizes?
With hydraulic hose assemblies, one should consider several measurements to ensure their correct size — ID (inner diameter), OD (outer diameter), and length. Inner diameter is the bore of the hose and the size of the orifice that the fluid has to travel through over a particular length. The OD of the hose could be […]

How are clamping systems used in fluid power?
From a fluid power design perspective, the circuit and subsequent major components take the majority of the focus. Actuators, valves, pumps and conditioning components rightfully take center stage, leaving accessory components out of the design stage and left for the technicians to worry about during fabrication. However, factoring all parts – no matter how insignificant […]
