Products Description
Core advantages and characteristics
1. Outstanding pressure resistance and structural integrity
Double-layer high-strength steel wire braided layer: As the core reinforcing layer of Hydraulic Hose, the two-layer high-strength steel wire braided skeleton provides excellent impact resistance and pulse fatigue resistance, and can reliably withstand medium working pressure.
Excellent Oil resistance: The built-in synthetic rubber inner layer has outstanding resistance to various Hydraulic oils, lubricating oils, fuel oils and coolants, preventing failure caused by inner wall swelling or corrosion, and ensuring the pure flow of Hydraulic fluids.
Wear-resistant and weather-resistant outer rubber layer: The outer black smooth or fabric-texted rubber layer has excellent anti-wear, anti-weathering and anti-ozone capabilities, protecting the internal Wire Braid Reinforcement from mechanical damage and environmental influences.


2. Excellent flexibility and ease of use
Good bending radius: Compared with four-layer wire wound hoses of the same pressure rating (such as R12), 2SN hoses are more flexible, easy to install and wire in compact equipment Spaces, and reduce installation stress.
Lightweight design: Its structure achieves lightweight while ensuring strength, facilitating transportation and system integration, and helping to reduce the overall weight of the equipment.
3. High cost performance and economy
2SN hydraulic hoses are one of the most economical choices for medium-pressure applications. It provides the reliable performance and long service life required by Hydraulic Hose Specifications at a reasonable cost, effectively controlling the maintenance and replacement budget.
4. Wide compatibility and applicability
This Hose is fully compatible with the standard manufacturing processes of SAE 100R2-based Hose Fittings and Hose Assemblies, and can be easily fabricated into various specifications of Hydraulic Hose Assembly to meet the connection requirements of different equipment.
