Hydraulic Hose Pipes and Fittings: How Important Are These?

Blog | April 28th, 2017

When mobile hydraulics gear requires instantly accessible torque, high-performance hydraulic hose pipes and fittings step up to the mark. Yes, these are very important circuit elements, but enough with the rhetoric. In place of that wordiness, let’s look at some hard and fast examples that prove just how system-essential fluid conveying components are in a working machine. We start this practical look with hose pipe functions.

Demonstrating Hydraulic Hose Pipe Importance 

Principally built to transport the hydraulic medium from one parts assemblage to the next, a flexible hose is a robust but pliable length of sized tubing. The flexible channels are omnidirectional, which means they can bend to accommodate any installation angle and any attachment orientation. Thanks to that adaptable design, an engineer can place the various valves and fittings on a mobile lifter’s frame anywhere. Installed at an angle and location that improves performance, the primary component then easily hooks itself to the main fluid line by employing the properties of a malleable hose.

Hydraulic Fittings: An Overview 

If a pliable hose facilitates connectivity while delivering fluid conveyance strength, then the pipe fittings function as a system extensibility aid. They’re the male-to-male extenders, angled elbow joints, and various other important building blocks that extend and adapt a fluid line. They branch the circuit, connect sections, and generally form the interconnections that tie every actuator, valve and hose in place. In other words, these are the joining bits and coupling pieces that link every discrete system stage. Made from robust steel alloys, fittings families use standardised thread types, sleeves, and coupling formats to assure connectivity viability.

Evaluating System Importance 

A great deal of time has been spent talking about valves and actuators, pumps and fluid mediums. Granted, these are primary hydraulic components. Without them, no work could be done. Still, these fundamental system assets would be isolated lumps of steel unless an equally fundamental fluid supply line threaded its way between the working elements. We’re referring to the plain oil-resistant rubber hoses and their wire-braid cousins, the variants that easily handle -40° to 100° C of thermally stressed, pressure-driven hydraulic oil. Similarly, the body, nut, sleeve and seal area within a standard fitting must be rated to cope with this constrained fluid medium, for a substandard seal could undermine the entire lift.

Potentially, it’s true, a poor seal could weaken the lifter. Depending on the location of that fittings flaw, a clamping mechanism could fail, then release a suspended load, perhaps a pallet full of masonry bricks. Keep that possibility firmly in mind when installing hydraulic hose pipes and fittings. They’re small and hidden tidily behind other parts, but they’re also absolutely essential fluid power transmitting components.
