Steel Nut & Tail Couplings

Steel Nut & Tail Couplings are two-part hose fittings
made up of a tailpiece (which inserts into the hose) and a threaded steel nut that secures the fitting onto a mating connection. This combination offers a tight, pressure-resistant seal suitable for a variety of industrial applications. Often used with hose clamps or crimped ferrules, these couplings are particularly effective in high-pressure systems where secure connections are essential for safety and performance.

Made from steel, these fittings are built to resist impact, vibration, and wear — making them ideal for tough environments where plastic or lower-grade metals may fail.

At Integraflex, we supply a versatile selection of steel
hose connectors to meet a wide range of system requirements. Options include:

Standard Steel Nut & Tail Couplings
These feature a plain tail for insertion into the hose and a threaded nut for fastening onto male threads or flanged components. Suitable for general-purpose applications across air, water, and hydraulic systems.

High-Pressure Couplings
Designed to withstand elevated pressure levels, these fittings are ideal for use in systems where burst resistance and reliability are non-negotiable.

Threaded Couplings
Tail sections are available with a variety of thread types (BSP, NPT, etc.) for compatibility with existing pipework or hose assemblies.

Galvanised and Zinc-Plated Options
Many of our couplings come with corrosion-resistant finishes to extend service life in outdoor or aggressive environments.

All our couplings are manufactured to high tolerances,
ensuring a consistent fit and long-term reliability in your hose setup.

Steel Nut & Tail Couplings are widely used in
heavy-duty and industrial applications where strength and durability are essential. Typical uses and industries include:

• Construction – Connecting hoses on compressors, tools, and water delivery systems
• Manufacturing – Transferring fluids in factory or plant operations, especially under pressure
• Agriculture – Handling irrigation systems, pesticide sprayers, and slurry equipment

Oil &Gas – Supporting safe fluid transfer under demanding environmental and pressure conditions

Transport & Logistics – Used in tanker hoses and fuel lines where vibration and movement are common

Chemical Processing – When paired with appropriate hose types, these couplings help manage aggressive or hazardous fluids

Their steel construction and pressure-handling capability make them an excellent choice where other connectors might degrade or fail under stress.

Selecting the correct steel hose connector for your system requires consideration of several factors:

Hose Size and Compatibility – Ensure the tailpiece matches your hose’s internal diameter, and that the nut thread fits your connection

Pressure Rating – Check that the coupling can handle the system’s working pressure safely

Material Coating – For environments with exposure to moisture or chemicals, choose galvanised or coated couplings to prevent corrosion

Application Type – Consider the media being transferred (air, water, oil, fuel, etc.) and ensure compatibility with steel components

Connection Standards – Match thread types such as BSP or NPT to your system’s fittings

If you’re unsure which type is right for your application,
our team is always happy to provide guidance to ensure the best fit for performance and safety.
