We manufacture a full range of hydraulic hoses to meet every industrial need. Our extensive product line includes SAE and DIN EN series hoses, spiral hoses, and more. With over 20 years of expertise, we guarantee durability, reliability, and peak performance for your equipment.
When you need a versatile and reliable solution, our wire braided hydraulic hoses are a perfect choice. We reinforce these hoses with one or more layers of braided high-tensile steel wire, giving them the flexibility and durability you need. They’re ideal for medium to high-pressure jobs in construction, mining, and industrial machinery, ensuring your equipment performs reliably every time.
For your most demanding, heavy-duty applications, we recommend our wire spiral hydraulic hoses. We engineer these with multiple layers of spiraled steel wire to give them superior strength and resistance to extreme pressure surges. While they’re less flexible, their incredible robustness makes them essential for large-scale equipment like earthmovers and oil drilling machinery, providing the power and safety you depend on.
If your application requires a lightweight and highly flexible solution, our thermoplastic hydraulic hoses are the answer. We manufacture these from high-quality synthetic materials, which makes them resistant to chemicals, UV radiation, and kinking. These hoses are perfect for low to medium-pressure systems and mobile equipment, giving you a smaller bend radius and the reliability you need in tight spaces.
We understand that not every application needs high pressure. Our textile braided hydraulic hoses are designed for low-pressure environments, such as return lines, air lines, and lubrication systems. We use high-strength textile fibers for reinforcement, giving you a lightweight and highly flexible hose that is easy to route and install in tight spaces.
When you need to move fluids to or from your hydraulic system’s reservoir, our suction and return hydraulic hoses are the perfect solution. We build these hoses with a strong reinforcement to prevent collapse under vacuum, while still providing the flexibility you need. They are designed for low-pressure applications, ensuring a smooth flow of fluid and preventing damage to your system.
When you’re dealing with extreme temperatures or aggressive chemicals, you need a hose that can handle it all. Our PTFE hydraulic hoses, also known as Teflon hoses, are made with a non-reactive inner tube and reinforced with stainless steel wire braid. This construction gives you a hose with excellent chemical compatibility, high temperature resistance, and a longer service life, making it perfect for specialized industrial applications.
We offer a complete range of hydraulic hoses engineered to meet diverse pressure ratings. From low-pressure return lines to ultra-high-pressure spiral hoses for heavy machinery, our products are manufactured to strict SAE and DIN EN standards. You can count on our hoses for durability, reliability, and safe operation in any application.
SAE 100R3: A low to medium-pressure hose reinforced with two braids of synthetic textile fibers, making it lightweight and flexible. It’s suitable for hydraulic return lines and applications where a steel braid isn’t needed.
SAE 100R4: This hose is designed for low-pressure suction and return lines. It features a textile reinforcement with a spiral steel wire to prevent collapse under vacuum conditions.
SAE 100R6: This is a very lightweight, low-pressure hose with a single textile braid reinforcement, ideal for general-purpose hydraulic systems.
SAE 100R1: A common high-pressure hose reinforced with a single braid of high-tensile steel wire. It’s a versatile workhorse for many hydraulic applications.
SAE 100R2: Similar to the 100R1, but for higher pressure applications. This hose is reinforced with two braids of high-tensile steel wire, offering greater strength and durability.
SAE 100R5: This is a medium-pressure hose that combines a single wire braid with a textile braided cover. It’s often used in automotive applications like air brakes and power steering systems.
SAE 100R16: A more compact version of the 100R2. This hose has a smaller diameter but performs at similar pressure ratings, making it a great choice when you need a more flexible hose for tight spaces.
SAE 100R17: A high-pressure, compact hose reinforced with one or two steel wire braids. It’s designed to be lightweight and highly flexible while maintaining a 3000 psi constant working pressure across all sizes.
SAE 100R3: A low to medium-pressure hose reinforced with two braids of synthetic textile fibers, making it lightweight and flexible. It’s suitable for hydraulic return lines and applications where a steel braid isn’t needed.
SAE 100R4: This hose is designed for low-pressure suction and return lines. It features a textile reinforcement with a spiral steel wire to prevent collapse under vacuum conditions.
SAE 100R6: This is a very lightweight, low-pressure hose with a single textile braid reinforcement, ideal for general-purpose hydraulic systems.
SAE 100R7: A medium-pressure thermoplastic hose reinforced with synthetic fibers. It’s lightweight, non-conductive, and resistant to a variety of chemicals and weather conditions.
SAE 100R8: A high-pressure version of the 100R7, with multiple layers of synthetic fiber reinforcement. It’s also non-conductive and ideal for applications where electrical conductivity is a concern.
SAE 100R14: This is a specialty hose with a PTFE (Teflon) inner tube and a stainless steel wire braid reinforcement. It’s excellent for high-temperature and chemically corrosive applications.
SAE 100R18: A high-pressure thermoplastic hose designed for non-conductive applications, with a constant 3000 psi working pressure. It offers great flexibility and a tight bend radius.
At Kingdaflex, we offer hydraulic hoses with different cover types to meet the specific demands of your operating environment. The cover is critical for protecting the hose’s reinforcement and inner tube from external threats like abrasion and weather. We provide both smooth and wrapped cover options, each with unique advantages for your application.
We manufacture these hoses with a textured, fabric-imprinted outer layer. This finish results from our traditional curing process using nylon fabric strips. The wrapped cover provides excellent grip and is highly resistant to abrasion and weather, making it a reliable choice for heavy-duty applications in harsh industrial and outdoor environments where physical contact and wear are common.
We produce our smooth cover hoses using a more modern curing process that leaves a clean, sleek surface. This type of cover is not only aesthetically pleasing but also offers superior resistance to cracking from ozone exposure. Smooth covers are easier to clean and work well in tight, congested routing paths, as they are less likely to snag, ensuring a cleaner installation and easier leak detection.
Creating a hydraulic hose is a precise process to ensure it can withstand the high pressure and demanding conditions it will face. Here’s how we manufacture our hoses:
Inner Tube Extrusion: We begin by extruding a synthetic rubber compound through a specialized machine to create the inner tube. This process ensures a smooth and uniform inner diameter, which is crucial for the efficient flow of hydraulic fluid.
Reinforcement Layer Application: Next, we apply the reinforcement layer. Depending on the hose type, we use a braiding or spiraling machine to wrap high-tensile steel wire or textile fibers around the inner tube. This step is what gives the hose its strength.
Outer Cover Extrusion: After the reinforcement is in place, we extrude a final layer of durable rubber to create the outer cover. This protective layer shields the hose’s reinforcement from external elements like abrasion, weather, and ozone, extending its service life.
Vulcanization and Curing: The final hose assembly is then vulcanized, or cured, under heat and pressure. This process bonds all the layers—the inner tube, reinforcement, and outer cover—into a single, strong, and durable unit that can withstand high pressure.
Quality Testing: Finally, we rigorously test each batch of hoses for quality and safety. We perform pressure tests to ensure they meet specified working and burst pressures, guaranteeing the reliability you need for your applications.
