hydraulic hose end fittings manufacturer

Kingdaflex, as a leading hydraulic hose end fittings, and we can customize all types of hydraulic hose end fittings.

Material Selection

Base Metal: Choose from various materials like steel (different grades for pressure and temperature resistance), stainless steel (corrosion resistance), or even brass (for lower pressure applications).

Flange Design

  • Flange Type: Select between common flange types like SAE J518 (4-bolt flange), SAE 61 (split flange), or custom designs for specific applications and space constraints.
  • Port Size and Thread: Specify the port size (diameter) and thread type (e.g., NPT, BSP) to match the hoses and components you’re connecting.

Sealing Options

  • O-Ring Material: Pick an O-ring material compatible with your fluid type and operating temperature for optimal sealing performance. Consider materials like Nitrile, Viton, or PTFE.
  • Sealing Configuration: Decide on the sealing configuration within the fitting, such as a single O-ring or a double O-ring design for added security in high-pressure applications.

Surface Treatment (optional)

  • Plating: For additional corrosion resistance or improved appearance, consider plating options like zinc plating or nickel plating.
  • Paint or Coating: Choose a paint or coating that offers protection against environmental factors or specific chemical exposure relevant to your application.

Various hydraulic hose end fittings

crimp on hydraulic hose end fitting

Crimp-on fittings

A popular choice due to their ease of installation using a crimping tool and dies. They come in various sizes and materials to suit different hose types and pressure requirements.

flange elbow fittings​

Hydraulic Flange fittings

Offer secure connections for high-pressure applications. They consist of a flanged collar with holes for bolts and a sealing surface that mates with a flange on the component. For more detailed info about hydraulic hose flange fittings, please feel free to contact us at any time. 

npt hydraulic hose fittings

NPT (National Pipe Thread) fittings

Commonly used for threaded connections to valves, pumps, and other components. They come in various thread sizes and are rated for different pressure applications.

quick disconnect couplings

Quick-disconnect couplings

Allow for easy connection and disconnection of hoses, ideal for applications requiring frequent assembly and disassembly. They come in various configurations and pressure ratings.

Hydraulic Hose End fitting FAQs

Hydraulic hose end fittings are components that attach hydraulic hoses to other components in a system. They create a secure and leak-proof connection for high-pressure fluid flow.

  • Secure connections: Fittings distribute pressure evenly, reducing the risk of leaks.
  • Versatility: Available in various sizes, materials, and types to suit different applications.
  • Ease of use: Many fittings (especially crimp-on) can be installed with readily available tools.
  • Reusability (depending on type): Some fittings, like flanged types, can be reused after hose replacement.
  • Cost: Compared to welded connections, fittings can be more expensive.
  • Improper installation: Requires proper assembly techniques and tools to ensure a secure connection.
  • Maintenance: Regular inspection and potential replacement of worn or damaged fittings is necessary.
  • Pressure rating: Choose a fitting with a pressure rating exceeding your system’s operating pressure.
  • Hose compatibility: Ensure the fitting matches the hose size and type (e.g., braided vs. spiral).
  • Component compatibility: Match the thread type (e.g., NPT, BSP) and port size to the component you’re connecting to.
  • Material: Select a material like steel or stainless steel for durability, considering corrosion resistance if needed.

Installation methods vary depending on the fitting type. Common methods include crimping (using a crimping tool and dies), screwing onto threaded ports, or bolting for flanged connections. Always refer to the manufacturer‘s instructions and use the proper tools for a secure connection.

Yes, to a certain extent. Customization options include:

  • Material selection: Choose the base metal and O-ring material based on pressure, temperature, and fluid compatibility.
  • Sealing options: Pick the O-ring material and configuration (single or double) for optimal sealing.
  • Flange design (flange fittings only): Select a standard flange type or a custom design for specific needs.
  • Surface treatment (optional): Consider plating or coating options for corrosion resistance or improved appearance.
