SAE 100R4 Low Pressure Hose
Product Description
SAE 100R4 Low Pressure Hose
Product Introduction:
Our SAE 100R4 Hose is a high-performance, low-pressure hydraulic hose specifically designed for the conveying of petroleum-based hydraulic oils in a wide range of mechanical equipment. It is engineered for use in suction lines and return lines within hydraulic systems, where reliable oil flow under vacuum or low pressure is required.
This hose is widely used across construction machinery, agricultural equipment, industrial machines, material handling equipment, marine hydraulics, and mobile hydraulic systems. It delivers safe, durable, and efficient hydraulic oil transfer in demanding operating environments.

Key Features:
1.Designed for Suction & Return Lines
Engineered specifically for low-pressure hydraulic circuits – ideal for conveying hydraulic oil from reservoir to pump (suction) and from components back to reservoir (return).
2.Petroleum-Based Oil Compatibility
The synthetic rubber inner tube resists swelling, softening, and degradation caused by mineral hydraulic oils, lubricating oils, and other petroleum-based fluids commonly used in machinery.
3.Vacuum / Anti-Collapse Construction
Built with a spiral fabric reinforcement and optional steel wire helix, the hose maintains its round cross-section under vacuum – preventing collapse in suction line applications.
4.Smooth Bore for Efficient Flow
The smooth inner surface minimizes flow resistance and turbulence, ensuring consistent hydraulic oil delivery without cavitation or pressure drop.
5.Abrasion & Weather Resistant Cover
The outer rubber cover resists abrasion, UV radiation, ozone, oil splashes, and moisture – suitable for outdoor machinery, construction sites, and industrial environments.
6.Wide Temperature Range
Operates reliably from -40°C to +100°C (-40°F to +212°F), accommodating cold starts and continuous hot oil return cycles.
7.Flexible & Easy to Route
Remains flexible for easy installation around frames, engines, and hydraulic components – yet resists kinking during handling.
