The outer layer is often weather-, oil-, or abrasion-resistant, depending upon the type of environment the hose is designed for. Not surprisingly, hydraulic hoses have a finite life. Proper sizing and use of the correct type of hose will certainly extend the life of a hose assembly, but there are many different factors that affect a hose's lifespan. SAE identifies some of the worst offenses as: 1  flexing the hose to less than the specified minimum bend radius. 2  twisting, pulling, kinking, crushing, or abrading the hose. 3  operating the hydraulic system above maximum or below minimum temperature.
This stretch of Appalachian Trail leading from Cramptons Gap to Harpers Ferry, West Virginia, is one of the most popular and rewarding AT day hikes in this region, with good reason.
