Let’s dive in!
What Is Hydraulic Hose SC
In the industry of hydraulics, the abbreviation “SC” typically refers to a specific type of hose construction.
It usually signifies a hydraulic hose with:
- Two steel wire braids: This provides high strength and pressure resistance, making SC hoses suitable for demanding applications.
- Smooth outer cover: This type of cover offers good abrasion resistance and is often preferred in applications where the hose may come into contact with other components or surfaces.
2SC Hydraulic Hose Vs 1SC Hydraulic Hose
The primary difference between 2SC and 1SC hydraulic hoses lies in their reinforcement:
2SC Hoses: These hoses feature two steel wire braids. This double layer of reinforcement significantly enhances their:
- Pressure resistance: 2SC hoses can withstand much higher pressures compared to 1SC hoses.
- Strength: The extra braid provides greater durability and resistance to external forces.
1SC Hoses: These hoses have a single steel wire braid. This makes them:
- More flexible: 1SC hoses are generally more bendable and easier to route compared to 2SC hoses.
- More cost-effective: The single braid construction reduces manufacturing costs, making 1SC hoses typically more economical.
Here’s a table summarizing the key differences between 2SC and 1SC hydraulic hose:
| Feature | 2SC Hose | 1SC Hose |
|---|---|---|
| Reinforcement | Two steel wire braids | One steel wire braid |
| Pressure Rating | Higher | Lower |
| Flexibility | Less flexible | More flexible |
| Cost | Generally more expensive | Generally more cost-effective |
| Applications | High-pressure applications, heavy-duty equipment | General industrial, lower-pressure applications |
- Choose 2SC hoses when you need to handle extremely high pressures and require maximum strength and durability.
- Choose 1SC hoses when flexibility and cost-effectiveness are more critical factors.
Note: These are general guidelines. Always consult the manufacturer‘s specifications and industry standards for precise details and performance characteristics of specific 2SC and 1SC hose models.
Key Characteristics of SC Hydraulic Hoses:
- High Pressure Capability: SC hoses are designed to handle high-pressure hydraulic fluids, making them suitable for heavy-duty applications.

Remember: While “SC” generally refers to this specific hose construction, it’s always essential to consult the manufacturer‘s specifications and industry standards for precise details and performance characteristics.
What Is Hydraulic Hose SN
In the hydraulic industry, the abbreviation “SN” typically refers to a specific type of hose construction. It generally indicates a hydraulic hose featuring:
- One steel wire braid: This provides a good balance of strength and flexibility, making SN hoses suitable for a wide range of applications.
- Smooth outer cover: Similar to SC hoses, SN hoses often have a smooth outer cover for enhanced abrasion resistance.
1SN Hydraulic Hose vs 2SN Hydraulic Hose
The primary difference between 1SN and 2SN hydraulic hoses lies in their reinforcement:
- 1SN Hydraulic Hose: These hoses have a single steel wire braid for reinforcement. This provides a good balance of strength and flexibility, making them suitable for a wide range of applications where moderate pressures are involved.
- 2SN Hydraulic Hose: These hoses feature two steel wire braids, significantly enhancing their strength and pressure resistance. This makes them suitable for applications that demand higher pressure capabilities.
Here’s a table showing you the key differences between hydraulic hose 1sn and hydraulic hose 2sn :
| Feature | 1SN Hose | 2SN Hose |
|---|---|---|

| Pressure Rating | Moderate | Higher |
| Flexibility | Generally more flexible | Less flexible than 1SN |
| Strength | Good strength | Higher strength |
| Cost | Typically more cost-effective | Generally more expensive |
In essence:
- Choose 1SN hydraulic hoses for applications requiring good flexibility and moderate pressure handling.
- Opt for 2SN hydraulic hoses when higher pressures are involved and greater strength is required.
Important Note: Always refer to the manufacturer‘s specifications and industry standards for precise pressure ratings, temperature limits, and other critical performance characteristics.
Key Characteristics of SN Hydraulic Hoses:
- Good Pressure Resistance: SN hoses can withstand moderate to high pressures, making them suitable for various hydraulic applications.
- Flexibility: The single steel wire braid construction offers good flexibility, allowing for easier routing and installation.
