Medium
Rubber hoses serve specific purposes. For instance, a rubber water hose is designed to deliver water. But never use it for oil. Why? Each specialized rubber hose uses unique materials. Using the wrong medium can cause failure. While some multipurpose hoses exist, most are made for specific uses.
Work Condition
Every hose has defined working limits. Always use hoses within their specified ranges. Using them beyond these limits damages the hose and shortens its lifespan.
Bending Radius
Using a bend radius smaller than recommended will drastically shorten the hose’s lifespan. Moreover, avoid sharp bends near connector ends.
Torque
Never operate hoses while they are twisted. Twisting damages the rubber and reduces durability.
Vibration
Vibrations subject hoses to thermal and fatigue stress, which can cause cracks near joints. Therefore, hoses should be tested for stress tolerance before factory shipment.
Kink
Some users kink hoses to restrict fluid flow, but this is not a recommended practice. Excessive stress on the reinforcement layer can lead to ruptures.
Choose a Proper Fitting
First, ensure the hose and joint pressure ratings match. Using a connector with a too-large diameter creates abnormal stress, tearing the reinforcement layer. A too-small diameter makes fastening difficult and causes leaks. Additionally, joints must have smooth edges to avoid damaging the hose. Use water or soapy water for assembly—unless the hose transports oils or solvents, never use them for fitting. Never use a mallet to soften the hose.
