Why You Can’t Press Hydraulic Hoses on Kubota Equipment

Your hydraulic hoses on your equipment are built to withstand wear and tear, but should they become damaged or start leaking, they could prevent your equipment from functioning as it should.

Checking for signs of wear and looseness on your equipment is an integral component of regular maintenance, and can save both time and money in the long run. A quick inspection could save both.

1. The hose is kinked

Hydraulic hoses are integral parts of hydraulic systems that move pressurized fluid for force transmission and energy transfer. With such systems, low input pressure can quickly turn into high output pressure levels that provide both power and control capabilities.

The most frequently used hydraulic hose is composed of rubber with steel wire braiding. This material offers great abrasion and temperature resistance, making it suitable for industrial environments. Furthermore, its lower memory means less likely kinks when in use.

Other types of hydraulic hoses include thermoplastic hoses with wire reinforcement and Teflon (also known as PTFE) hoses with stainless steel braiding - more lightweight alternatives to rubber and steel but still offering good resistance against abrasion and high temperatures, these types are often used for chemical transfer applications but must be protected and maintained regularly or they risk degradation over time.

2. The hose is bent

A hydraulic hose's minimum bend radius refers to its maximum circumferential movement in one direction without becoming damaged and unusable, without becoming compromised and unsafe to use. It is determined by multiple factors including construction materials, core design and layers of reinforcement - for instance braided steel will have tighter bend radii than spiral.

If the hose will be subjected to dynamic conditions during operation, such as movement during its use, its manufacturer may recommend employing a dynamic bend radius instead. This is calculated by multiplying its static counterpart with an appropriate bend factor (typically between 1.1 and 1.5).

3. The hose is damaged

Hydraulic hoses consist of an inner tube made of rubber or thermoplastic, reinforced layers consisting of braided or spirally applied wire reinforcement and an outer cover. Their inner tubes must be properly matched to adapters and couplings that take advantage of all their rated pressure and performance capabilities, and routed in such a way that external heat sources do not expose them prematurely and result in loss of hydraulic pressure and catastrophic loss.

Damaged hydraulic hoses must be repaired or replaced as quickly as possible to avoid costly system damage and downtime. To address a leaking hydraulic hose, first make sure the system is safe for working by relieving pressure, lowering pieces and removing components to create an unobstructed workspace. Next, loosen fittings and remove the damaged hose; be mindful not to over-tighten as this may have detrimental effects on system performance.

4. The hose is leaking

Hydraulic hoses are not meant to leak. When they do, however, this can be devastating as the release of high-pressure hydraulic oil from them poses fire hazards and environmental dangers; in addition, its release reduces machine performance and efficiency.

If you notice any leakage in a hose, it is vital that it is repaired immediately. A small amount of oil loss during connection and disconnection may be normal; however, any significant leaking indicates it needs replacing immediately.

One common way of fixing leaks in hydraulic hoses is to splice and seal them with crimp or screw type fittings, but this approach may shorten its life while increasing leak risks in the future. A flare nut-crowfoot wrench makes removal of fittings from hose easier.
