Hydraulic and industrial hoses are designed to handle high pressures without leaking, yet normal wear and tear can still cause problems. In demanding environments such as mining, construction or marine operations, a single hose failure can halt production and expose workers to hazards. Regular inspection and maintenance are therefore critical.
Why do hoses leak?
Hydraulic hoses consist of three layers: an inner tube, a reinforced layer and an outer protective layer. Abrasion from flexing, twisting, kinking or crushing can fray these layers and allow hydraulic fluid to seep out. Improperly assembled fittings or worn seals are another common source of leaks. Over time, even a small hole can turn into a dangerous ruptur
Importance of inspection and maintenance
The safest way to prevent leaks is through scheduled inspections and preventative maintenance. se the manufacturer’s recommended hose lengths and diameters to minimise stress on the hose. Mount hoses securely using proper supports and restraints so the outer lining doesn’t chafe. During inspections, look for cracks, bulges or wear in the outer layer and replace hoses that show signs of damage.
Ensuring proper connections
leaks originate at the fitting. When installing hoses, make sure both ends are clean and undamaged, use the correct seals, avoid over‑tightening fittings and ensure the proper crimped connectors are used. Inadequate connections can cause fluid to escape under pressure, leading to equipment failure or injuries.
Detecting leaks safely
Never use your hand to check for a leak—high‑pressure fluid can puncture skin. Instead, run a piece of cardboard or wood along the suspected area; it will absorb fluid and pinpoint the leak. If you suspect a leak, shut down the system and relieve pressure before attempting repairs.
Conclusion
Hydraulic hoses are vital components that keep machinery operating smoothly. By implementing a regular inspection schedule, using the correct hose assemblies and fittings, and training staff on leak detection and safety, you can minimise downtime and keep your operations safe.
