### **Cons**
1. **Higher Initial Cost**
- Significantly more expensive than **standard hydraulic hoses** (e.g., SAE 100R1 or R2), which may be a barrier for budget-conscious buyers or small-scale operations.
- The premium price reflects its **superior materials and construction**, but it may not be justified for low-pressure or light-duty applications.
2. **Specialized Installation Requirements**
- Requires **proper crimping or flaring of fittings** to prevent leaks; improper installation can lead to premature failure.
- May need **specialized tools or trained personnel** for installation, unlike simpler hoses that can be fitted with basic equipment.
