Review GATES Genuine Emission Control And Ventilation Hose
The **Gates EMH790 Emission Control Ventilation Hose** is a high-performance, engineered air management solution designed to meet the stringent demands of modern diesel engine applications, particularly in heavy-duty vehicles, industrial machinery, and off-road equipment. Constructed from Gates proprietary **EPDM (Ethylene Propylene Diene Monomer) rubber compound**, this hose delivers exceptional resistance to oil, fuel, and environmental contaminants while maintaining flexibility across a broad temperature range, from -40 F to 257 F (-40 C to 125 C). Its reinforced spiral wire braid provides superior burst strength and dimensional stability, ensuring reliable airflow and structural integrity even under high-pressure differentials or dynamic vibrations common in demanding operating conditions. The hose s smooth, abrasion-resistant inner liner minimizes airflow restriction, optimizing engine performance and emissions compliance by facilitating precise exhaust gas recirculation (EGR) or positive crankcase ventilation (PCV) systems. Additionally, the **black, UV-stabilized outer cover** protects against ozone, weathering, and premature degradation, extending the hose s service life in harsh outdoor or industrial environments. With a **1.5/8" (4.76 mm) inner diameter and 1.125" (28.6 mm) outer diameter**, the EMH790 strikes an ideal balance between flow capacity and compact installation, making it a versatile fit for a wide range of aftermarket and OEM applications. Whether integrated into a turbocharged diesel engine, diesel particulate filter (DPF) system, or exhaust aftertreatment setup, this hose exemplifies Gates commitment to durability, precision engineering, and compliance with emissions regulations, ensuring dependable operation while reducing maintenance downtime.
**Pros and Cons of buying a Gates EMH790 Emission Control Ventilation Hose**
The Gates EMH790 is a high-performance emission control ventilation hose commonly used in diesel engine applications, particularly in heavy-duty vehicles and equipment. Below is a detailed analysis of its advantages and disadvantages.
### **Pros**
1. **High-Quality Materials** The hose is constructed from durable, heat-resistant materials designed to withstand high temperatures and corrosive exhaust gases. This ensures longevity and resistance to degradation over time.
2. **OEM Compatibility** Gates is a trusted manufacturer that produces hoses compatible with original equipment manufacturer (OEM) specifications. This reduces the risk of fitment issues and ensures proper function with emission control systems.
3. **Reliability in Emission Systems** The EMH790 is specifically engineered for diesel particulate filter (DPF) and exhaust gas recirculation (EGR) systems, which are critical for meeting emissions regulations. A well-functioning hose prevents leaks that could compromise system performance.
4. **Easy Installation** Gates hoses are designed with user-friendly features, such as clear labeling and proper sizing, making installation straightforward for mechanics and DIY enthusiasts.
5. **Warranty and Support** Gates offers warranties on its products, providing assurance against defects. Additionally, they have a strong reputation for customer support and technical assistance.
6. **Cost-Effective for Long-Term Use** While the upfront cost may be higher than some generic alternatives, the durability and performance extend the life of emission control systems, reducing the need for frequent replacements.
7. **Environmental Compliance** Using a high-quality hose ensures that the vehicle or equipment remains compliant with emissions standards, avoiding potential fines or failure in inspections.
### **Cons**
1. **Higher Initial Cost** Compared to generic or aftermarket hoses, the Gates EMH790 is more expensive. This may be a barrier for budget-conscious buyers, especially if the hose is not immediately critical.
2. **Limited Availability in Some Regions** Depending on location, the EMH790 may not be as widely stocked as other brands, requiring special ordering or longer wait times.
3. **Potential Overkill for Light-Duty Applications** If the hose is being used in a vehicle or machine with less demanding emission requirements, the robust design may be unnecessary, making it an overpriced solution.
4. **Installation Complexity in Some Cases** While generally user-friendly, certain applications particularly in tight or hard-to-reach areas may require professional installation, adding to labor costs.
5. **Compatibility Concerns with Non-OEM Systems** In aftermarket or modified systems, there is a slight risk that the hose may not perfectly match the intended application, though this is rare with Gates reputation for precision.
### **Conclusion**
The Gates EMH790 emission control ventilation hose is a superior choice for applications where reliability, durability, and compliance with emissions standards are paramount. Its high-quality construction, OEM compatibility, and long-term performance justify the higher cost for most heavy-duty and professional users. However, for budget-sensitive or light-duty applications, the expense may not be fully warranted, and alternatives could be considered.
### **Recommendation**
If you are working on a diesel vehicle or equipment that requires strict emissions control such as a truck, bus, or industrial machine **the Gates EMH790 is highly recommended**. Its performance and longevity will likely save money in the long run by preventing system failures and ensuring compliance. For less demanding applications, weigh the cost against the potential benefits, and consider whether a slightly less expensive but equally reliable alternative would suffice. Always verify compatibility with your specific vehicle or system before purchasing.
