Any given technician installing components during plumbing will tend to use the verbiage familiar to him or her and will use the words interchangeably. Of course, they are not the same, or they wouldn’t be segregated as two words […]
Hydraulics with a twist: Swivel connections remove stress from hose routing
Designers of hydraulics circuits are typically tasked with ensuring that hose and connections are safe, efficient, leak free and easy to maintain.

What are hydraulic hose swivels?
Most hydraulics engineers are well aware that proper hose routing often means accommodating machine motion without overly stressing the hose, or letting it rub and abrade against other hoses or machine components. Otherwise, hose can prematurely fail, resulting in leaks, machine damage, downtime, costly environmental contamination and, potentially, a hazard to nearby personnel. Swivel-type fittings […]
