1. Expertise and experience
The first and foremost factor to evaluate is the supplier's expertise and experience in the field of hydraulic fittings. Look for a company that has a long history of providing these components to various industries. An experienced supplier is more likely to understand your specific requirements and offer tailored solutions. They should have a team of knowledgeable professionals who can guide you through the selection process, ensuring you get the right stainless steel hydraulic hose and pipe fittings for your needs.
2. Quality assurance and certification
Hydraulic systems operate under high pressure and demanding conditions. Therefore, the quality of the fittings is of utmost importance. Verify that the supplier adheres to strict quality control processes and holds relevant certifications, such as ISO or AS - the Aerospace Management Standard. This ensures that their products meet international standards and undergo rigorous testing for durability and performance. High-quality fittings not only reduce the risk of system failures but also extend the lifespan of your equipment.
3. Wide range of products
Your hydraulic and piping needs may vary depending on your industry and application. A reputable supplier should offer a diverse range of hydraulic hose and pipe fittings to accommodate different sizes, materials, and configurations. This versatility allows you to find the perfect fit for your specific requirements, whether you need standard components or custom-made fittings. Additionally, having a comprehensive product range ensures you can source all your hydraulic fitting needs from a single supplier, simplifying procurement and logistics.
4. Reliability and on-time delivery
Downtime can be costly, so reliability is paramount. Look for a supplier with a proven track record of delivering orders on time and in full. Delays in receiving fittings can disrupt your operations and result in financial losses. Check if the supplier has a well-established distribution network and inventory management system to ensure prompt deliveries. A reliable supplier should also have contingency plans in place to address unexpected supply chain disruptions.
5. Customer support and technical assistance
Effective customer support and technical assistance are essential when choosing a supplier for hydraulic hose and pipe fittings. Ensure the supplier has a responsive customer service team that can address your inquiries, provide guidance, and assist with any issues that may arise. They should also offer technical support, including product recommendations, installation advice, and troubleshooting assistance. A supplier that values its customers' success and satisfaction is more likely to build a long-lasting partnership.
Conclusion
Selecting the right supplier for your stainless steel hydraulic hose and pipe fitting needs is a critical decision that can significantly impact your business's performance and efficiency. By prioritising expertise, quality assurance, product variety, reliability, and customer support, you can make an informed choice that ensures the smooth operation of your hydraulic systems and minimises downtime. Investing time in selecting the right supplier upfront can lead to long-term benefits and peace of mind in the reliability of your equipment.

Whether you are replacing an existing hose, or building a new system, you&#;ll need to select a hose of the correct pressure rating, diameter, and length and with the best material properties for your application. There are a few factors to consider carefully.
Material
Firstly, you should consider the conditions that a hose will operate under. The outer layer or cover of a hose can come in a variety of synthetic rubber materials. Some compositions can help with applications where abrasion may occur but may not bend as readily.
The most common materials are fluoropolymers and silicone, elastomers, metal, and thermoplastics. Composite or laminated materials are also common.

Rubber and elastomeric hydraulic hose are a strong choice when you need flexibility. A Fluoropolymer hose has a durable flex life, it also has excellent corrosion and chemical resistance and it can handle high temperatures.
Thermoplastic hydraulic hose has a tight minimum bend radius. It also features superior resistance to kinks. Thermoplastic hoses are generally much lighter than rubber hoses. The inner tube of copolyester or nylon is typically braided or spiral wrapped with a synthetic reinforcement fiber instead of steel. Synthetic fiber is also needed for electrically non-conductive (orange cover), aerial lift hoses. In many cases the outer cover of thermoplastic hoses will be polyurethane and provide a longer shelf life than rubber, better flexibility at low temperatures such as &#;60°C (&#;75°F), and higher resistance to UV and chemicals.
Metal hoses handle high temperatures and high flow materials well. They can also handle high pressures, as well as being either flexible or stiff.
Neoprene is one popular synthetic cover material that remains flexible across a wide range of temperatures, yet handles abrasion well. Most rubber hoses perform reasonably well from &#;40°C (&#;40°F) to 100°C (212°F).
Flexible hoses are easy to install and route compared to rigid tubing. The flexibility reduces noise and vibrations. It also dampens pressure surges and allows for movement between the parts.
Weight and Space
Another consideration when selecting a hose would be whether the weight and space are a concern, as is often the case with mobile machine. In this instance you would want to look for hoses with a thin-wall inner tube. Advances in synthetic rubber compounds allow for higher wall strength, allowing for a final product with a smaller outside diameter. Some manufacturers have moved to a reinforcement wire with an oval cross-section, as opposed to round, offering additional outside diameter (O.D.) and hose weight savings. These smaller O.D. hoses, referred to as compact models in many catalogues, also offer much tighter bend radiuses.
Inside diameter and Length
It&#;s very important to use a hose of the correct inside diameter. If the diameter is too small for a given rate of flow, the linear velocity will be too high and excessive velocity will translate into friction and turbulence, which when combined will surely result in noticeably higher system pressure and heat.
Correct hose length needs to allow for bending and flexing as a machine moves and articulates, and to make sure that no undue stress is caused at the crimped fittings. A hose that connects in a perfectly straight path from one component to another may shrink in length up to 4% at maximum pressure, so an allowance of extra length should be considered when making up the hose assembly. However, an excessively long hose adds restriction to flow, increasing system pressure and reducing system efficiency. A long hose length also requires a larger inner diameter to avoid excessive restriction and friction.
Pressure rating
A hose must be chosen with a maximum working pressure (WP) rating that is at or preferably above the normal maximum hydraulic system pressure. Momentary pressure surges for a hydraulic system are not to exceed this pressure rating. Hose fittings that are rated below the working pressure of the selected hose cause the entire hose assembly to be aligned to the lower rating of the fittings.
Burst pressure is a built-in safety factor for a hydraulic hose. A hose manufacturer verifies the burst pressure in a destructive test. The SAE standard J517 for the common series of 100R hydraulic hoses categorises leakage and also hose separation from hose fitting. The hose does not have to violently break apart completely to have suffered a burst failure. The burst pressure rating of a hydraulic hose if often 4x the working pressure rating or greater.
Price
When it comes to hydraulic design, hoses are not minor parts. Using economics as the only/primary hose selection criteria can easily leave human risks at a very high level. A hose burst failure is always a catastrophic incident. In the best case scenario, a hose failure might cause production downtime or environmental contamination concerns. In a worse scenario, persons could be seriously injured or even killed.
Hydraulic hoses comes in a myriad of design types and materials, and choosing the correct type for your application involves understanding several factors. You now have the rudimentary understanding needed to select the proper hydraulic hose for your needs. Remember that choosing the correct type and grade hose will extend its working life.
