The SAE 100 R4 Hydraulic Oil Suction Hose is a premium, high-strength synthetic textile reinforced hose engineered with an embedded helix steel wire. Specifically designed for the demanding environments of hydraulic systems, this versatile hose excels in both suction and discharge applications, ensuring a stable and unobstructed flow of petroleum-based, water-based liquids, and specialized hydraulic fluids.
Constructed with a sophisticated three-layer system—consisting of a high-performance inner tube, a robust reinforcement layer, and a protective outer wrap—the SAE 100 R4 is indispensable for low-pressure return lines and suction lines. Its advanced structural integrity prevents collapse under negative pressure, making it the ideal choice for mining hydraulic supports, oil field development, and heavy-duty engineering construction.

Frequently Asked Questions
A suction hose must withstand negative pressure. Without the embedded steel wire, the vacuum force created by the hydraulic pump can cause the hose to collapse, restricting oil flow and causing pump cavitation.
While it can handle discharge, it is specifically engineered for suction and low-pressure return lines. For extremely high-pressure applications, a different SAE specification may be required.
The compound used in the SAE 100 R4 is designed to resist stiffening in sub-zero climates and degradation in high-heat environments, ensuring consistent suction efficiency.
It is highly compatible with petroleum-based oils, water-based hydraulic fluids, and various oil-based liquids commonly used in industrial hydraulic systems.
Selection should be based on vacuum pressure intensity, minimum bend radius, and the actual layout of your machinery. We provide detailed data sheets and custom engineering support to ensure a perfect fit.
Direct sourcing ensures stable pricing, eliminates middleman delays, and provides guaranteed batch-to-batch quality uniformity through strict internal factory testing.
