The LEAD-FLEX SAE100 R7 hydraulic hose is a top-tier fluid conveyance solution engineered to meet the diverse needs of industrial, mechanical, and mobile equipment applications. Built with quality and performance in mind, this hose features a synthetic rubber inner tube for optimal fluid compatibility, a single fiber braid reinforcement for enhanced strength, and an oil and weather resistant outer cover for long-term protection. Whether used in stationary machinery or mobile equipment, the SAE100 R7 hose delivers consistent performance, combining flexibility, durability, and media compatibility to become an indispensable component in various fluid and gas conveyance systems.

The SAE100 R7 hydraulic hose is designed to handle varying pressure demands, with its single fiber braid reinforcement providing stable pressure resistance. This adaptability ensures the hose performs reliably in both low and medium pressure systems, reducing the risk of leaks or failures under fluctuating operating conditions.
Unlike rigid hoses that are difficult to maneuver, the LEAD-FLEX SAE100 R7 offers exceptional flexibility, allowing for hassle-free installation around equipment components, tight corners, and complex layouts. Its flexible design saves time during setup and reduces the need for additional fittings or adapters.
The outer cover’s oil and weather resistant properties are a key advantage, protecting the hose from oil spills, chemical exposure, and outdoor elements. This resistance extends the hose’s lifespan, minimizing replacement costs and downtime for maintenance.
With compatibility across a wide range of hydraulic fluids, water, and air, this hose eliminates the need for multiple specialized hoses. Businesses can streamline their inventory while ensuring they have a reliable solution for various conveyance needs.
In tractors, harvesters, and irrigation equipment, the SAE100 R7 hydraulic hose conveys hydraulic fluids and water, powering steering systems, lift mechanisms, and irrigation pumps. Its weather resistant cover withstands exposure to dirt, moisture, and outdoor elements, making it ideal for farm and field applications.
For excavators, loaders, and bulldozers, this hose plays a critical role in hydraulic systems, delivering fluids to hydraulic cylinders and motors. Its durability and pressure resistance enable it to handle the heavy-duty demands of construction sites, where equipment operates under intense stress.
In automated production lines and robotic systems, the hose conveys hydraulic fluids and compressed air to power actuators, grippers, and other components. Its flexibility allows for precise routing around moving parts, ensuring seamless integration into complex automation setups.
The oil and weather resistant properties of the LEAD-FLEX SAE100 R7 hose make it suitable for marine applications, such as small boats, docks, and offshore utility equipment. It reliably conveys hydraulic fluids and water, withstanding saltwater exposure and harsh marine environments.
Yes. The hose is fully compatible with compressed air, making it suitable for pneumatic tools, air compressors, and pneumatic control systems. Its airtight design ensures minimal pressure loss, supporting efficient tool and equipment operation.
The combination of the synthetic rubber inner tube, single fiber braid reinforcement, and oil and weather resistant outer cover creates a robust structure. This design resists wear, abrasion, chemical exposure, and environmental damage, ensuring the hose maintains performance over extended periods.
No. The LEAD-FLEX SAE100 R7 hose is designed for industrial hydraulic fluids, water, and air—not food-grade materials. For food-related applications, please select hoses specifically certified for food contact.
Yes. The hose can be cut to custom lengths to fit specific installation needs. However, proper cutting and fitting techniques should be followed to ensure a secure, leak-free connection and maintain the hose’s structural integrity.
Constructed with three functional layers, the SAE100 R7 hose features a synthetic rubber inner tube that ensures superior sealing and resistance to fluid degradation. The single fiber braid reinforcement layer adds structural strength, enhancing pressure tolerance and preventing deformation. The outer layer is crafted from oil and weather resistant rubber, providing a barrier against abrasion, UV rays, and environmental moisture. The hose is designed to operate within a wide temperature range, adapting to both hot and cold conditions, and is compatible with most common hydraulic fluids and gases. Importantly, it is not intended for phosphate ester groups, so users should avoid these media to preserve hose integrity. The overall design prioritizes both performance and longevity, making it a reliable choice for continuous operation.
