What Are the Key Factors to Consider When Choosing Hose Assemblies?
Selecting the right hose assembly is essential for safety, compliance, and reliable performance across industrial, food, beverage, pharmaceutical, and chemical applications. A well-chosen hose assembly supports operational efficiency, reduces downtime, and helps you meet regulatory requirements.
This in depth guide explores the most important factors to consider, with practical advice, technical context, and expert insights.

Understanding the Application and Media for Hose Assemblies
Begin by clearly defining your application and the type of media being used. Are you transferring chemicals, food products, water, steam, gases, or abrasive materials? Each media presents unique compatibility and safety requirements. For example, brewery hoses must be resistant to alcohol and caustic cleaning agents, while food and beverage hoses must meet strict hygiene standards to prevent contamination and preserve product quality. Whereas chemical hoses require resistance to aggressive substances and must be compatible with the chemicals in use. Once you establish this, you can choose the right hose for the job.
For more application-specific guidance, see our hose assemblies selection guide.
Pressure and Temperature Ratings in Hose Assembly Selection
Always select a hose assembly with pressure and temperature ratings that exceed your system’s maximum operating conditions. Overlooking these ratings can result in hose failure, leaks, or safety hazards.
Check both the working and burst pressure, as well as the minimum and maximum temperature limits. For applications involving steam, hot water, or cryogenic conditions, choose hoses specifically rated for those extremes. Brewery hoses, for example, must withstand high temperatures during cleaning and sanitisation.
For technical specifications, refer to our hose assemblies selection.
Hose Material and Construction: Durability and Compatibility
Material selection is critical for durability, flexibility, and compatibility. Common hose materials include PTFE for chemical resistance and hygiene, EPDM and NBR for general industrial and food applications, stainless steel for high pressure or aggressive environments, and PVC or polyurethane for flexibility and abrasion resistance.
The construction of the hose is important too—such as braided, convoluted, or reinforced—as these impact flexibility, pressure rating, and service life. Specialist brewery hoses, for example, are made from butyl for resistance to alcohol and cleaning agents.
For a breakdown of available options, see custom hose assemblies.
End Fittings and Connection Types for Hose Assemblies
Choosing the correct end fittings is essential for a secure, leak-free connection. Consider threaded (BSP, NPT, JIC) or flanged connections for industrial systems, hygienic fittings (Tri-Clamp, DIN, RJT, SMS, IDF) for food and pharma, and camlock, quick-release, or dry disconnect couplings for fast changeovers. The compatibility of fitting materials with both the hose and the process media is also vital. Flextech’s Shawlok™ range offers hygienic, permanent swaged fittings across many demanding applications.

Compliance, Certification, and Regulatory Standards
Your hose assembly must meet all relevant industry standards and regulatory requirements, such as FDA, EN 12115, or USP Class VI for food and pharma, ATEX for explosive environments, and PED or CE marking for pressure equipment. And when ordering, always request documentation and certification from your supplier.
At Flextech, we always provide full batch traceability and can supply 3.1B certificates for hygienic hose assemblies.

Hose Length, Routing, and Flexibility
Accurately measuring the required hose length is a critical first step to ensure a successful installation. When measuring, take into account not only the straight-line distance but also any bends, movement, and routing constraints that the hose will encounter in its application. Avoid sharp bends or kinks, as these can cause premature wear, reduce flow efficiency, and ultimately lead to hose failure.
Select a hose with the appropriate flexibility and a minimum bend radius that matches your specific installation requirements because using a hose that cannot accommodate the necessary bends may compromise performance and durability.
For longer hose runs or those suspended in position, install support brackets, guides, or clamps to prevent sagging, reduce strain, and maintain proper alignment. Proper support also helps extend the hose’s service life by minimising fatigue and mechanical stress.

Abrasion, Chemical, and Environmental Resistance
Understanding the environmental challenges your hose will face is crucial to selecting the right product. Carefully assess the external environment where the hose will be installed and operated. Factors such as abrasion from contact with rough surfaces, exposure to UV radiation, ozone, moisture, and various chemicals can significantly reduce the hose’s lifespan and performance.
To ensure durability and reliability, select hoses equipped with suitable protective covers or liners specifically designed to resist these hazards. For example, abrasion-resistant outer covers protect against physical wear, while specialised chemical-resistant liners prevent degradation from aggressive substances.
Considering these environmental factors during hose selection helps minimise maintenance needs, prevent premature failures, and extend overall service life.
For chemical compatibility, refer to our chemical compatibility guide.
Maintenance, Inspection, and Hose Asset Management
Regular inspection and maintenance are essential to ensure safety and maximise the long-term performance of your hose assemblies. During routine checks, carefully look for signs of wear, abrasion, or physical damage; leaks or bulges around fittings; as well as any loss of flexibility or visible degradation of the liner.
Promptly addressing these issues can prevent unexpected failures and costly downtime. Be sure to document all inspections and maintenance activities in your asset management system to maintain a comprehensive service history and support effective lifecycle management.
Flextech’s hose asset management programme can help you track hose condition, schedule replacements, and manage hose registers.
Custom and Specialist Hose Assemblies
Some applications require bespoke hose assemblies, such as high-pressure or high-temperature hoses for steam or gas, anti-static or electrically conductive hoses for ATEX zones, or special lengths, diameters, or end connections for unique installations.
Flextech offers custom hose assemblies and technical support to meet your specific needs, including design, product development, and on-site surveys.
Testing, Traceability, and Documentation for Hose Assemblies
We cannot stress this enough: always ensure your hose assemblies are properly tested and fully traceable.
Depending on your application—especially in safety-critical environments—hydrostatic, pneumatic, or electrical continuity testing may be mandatory to verify integrity and performance.
Always request comprehensive test certificates from your supplier and maintain detailed records of all testing and inspections. This documentation is vital not only for regulatory compliance and audit readiness but also for effective asset management and risk mitigation.
Flextech provides hose inspection and testing services and operates a full batch traceability system for all machined components and hose compounds.
Hose Assembly Installation and Best Practices
Proper installation is as important as selection. Always follow manufacturer instructions and recommended torque settings, avoid twisting, kinking, or over-bending the hose, use correct tools for fitting installation, and pressure test the assembly after installation.

Selecting Hose Assemblies for Chemical and Industrial Use
Selecting the right hose for chemical and industrial applications is critical to ensuring safe and reliable operation.
Hoses used in these environments must be compatible with aggressive media and durable enough to withstand harsh conditions such as high temperatures, pressure fluctuations, and exposure to corrosive substances. Materials like PTFE, UHMWPE (Ultra-High Molecular Weight Polyethylene), and stainless steel are commonly chosen for their excellent chemical resistance and mechanical strength.
To make the best selection, always consult a chemical compatibility chart to verify that the hose material is suitable for the specific media it will convey. Additionally, ensure the hose’s pressure rating meets or exceeds the system requirements to handle both normal operating pressures and potential pressure surges. Choosing hoses with the right material composition and pressure capacity helps prevent premature failure, leaks, and safety hazards, ultimately protecting both your processes and personnel.
