From Bernini the Original No Kink Metal Garden Hose®. Often imitated, never duplicated. Featuring durable 304-grade stainless steel construction that is UV and corrosion-resistant, this lightweight, flexible hose stays cooler in the sun than other hoses and won't kink or puncture. Drag it through your rose bushes or around metal fences without worry! What sets our metal hoses apart from others on the market is our patented Power Coupler, which allows the hose to pass a 90-degree pull test, which would cause other metal hoses to break. Included is a twist-style fireman nozzle that can tackle all your watering needs, from a fine mist to water delicate plants to a powerful spray that is great for washing the car or cleaning concrete.

A metal hose has several applications. Be it food processing or gas and oil distribution, there are a range of hoses and fittings to choose from. You might also have questions in your mind like: why use a metal hose or what are the uses of metal hoses? Is it safe? Is it cost-efficient for my industrial application? This blog aims to answer these questions and will provide an overview of the applications of a metal hose and the factors involved in the same.

A metal hose is flexible piping available in two basic types based on design and application. The types of metal hose are strip wound hose and corrugated hose.
One of the most frequently asked questions is when to use a metal hose. While there are different types of hose available in the market, like rubber hose, composite hose, PTFE hose, and fabric hose, the many advantages of a metal hose make it the most sought-after option.
Many industries use metal hose assemblies due to their ease and durability. Applications of metal hoses include connecting gas lines to moveable appliances and the transfer of oil, steam, or water. However, the final decision on which type of hose to buy depends on its application.
Here are a few factors that can help you determine when to use a metal hose:
If the atmospheric temperature or the temperature of the media going through the hose is extremely hot or cold, then metal hose might be the only material that can withstand such temperature extremes.
Metal hoses can handle a wider range of chemicals than other hose types. A metal hose should be considered if your application exposes the hose to aggressive chemicals internally or externally. Stainless steel shows good resistance to chemicals and alloys can be used with metal hoses to make them corrosion resistant.
With non-metal hoses, there is a possibility that gases will permeate through the hose wall and into the atmosphere. Whereas, permeation is unlikely with metal hoses when properly fabricated.
In times of failure, metal hoses develop small holes or cracks while other hoses develop larger cracks or completely come apart. Moreover, the fittings are welded to metal hoses hence fitting retention problems are unlikely here. If the sudden failure of the hose is catastrophic, the metal hose will minimise the effects of a failure by making sure that the product leaks at a slower rate.
A metal hose can be used as a protective cover over wires and even other hoses to prevent abrasion and overbending. Strip wound hoses are very abrasion resistant and are ideal to be used as protection. They can be applied to the outside of a corrugated hose to prevent it from overbending. One way to test the metal hose of an assembly is by bending a corrugated hose, as the strip wound hose cannot be over-bent without pulling apart the hose.
While other types of hose will melt when exposed to fire, metal hose maintains its fire resistance up to 1200 degrees F. Corrugated hoses are the better choice when it comes to fire resistance and low permeation in cases where the hose may be exposed to open flame or for applications of barge loading and unloading.
Metal hose maintains its shape under full vacuum while other types of hose might collapse. Corrugations in a metal hose render excellent hoop strength resulting in its ability to handle a full vacuum. Helix wires are used in non-metallic hoses to improve their vacuum rating. However, collapse is still a possibility.
Any kind of weld-able fitting can be incorporated into a corrugated hose assembly and in any configuration. Whereas, other types of hose require special collars and shanks for the same. This is an advantage over other types of hoses that would require multiple threaded connections to connect multiple hoses. Every threaded connection is a potential point of leakage. Hence, wielded fitting eliminates any leakage point and can facilitate smooth installation.

The factors to be taken into consideration while using a metal hose are similar to the advantages of usage and applicability it provides.
Here are the factors one must consider while using a metal hose:
Would a hose failure be disastrous in terms of injury or downtime? Or as we call it, a catastrophic failure in the industrial language. Generally, the fittings of a metal hose are welded as compared to clamped or crimped in a traditional metal hose. When a failure occurs, the welded fittings of a metal hose develop small cracks as opposed to large cracks and blowouts in the case of a non-metal hose.
Metal hoses are rated well for their wide range of abrasive and corrosive chemical compatibility. All hose fittings and other assembly components are rated to withstand chemical attacks from chemicals in the external environment as well as within the conveyed material.
Gas can seep in due to permeable hose walls of the non-metal hose, while the expertly fabricated metal hose assemblies do not allow gases to pass through their wall. Since there is no cross-contamination to the material of the hose, stainless steel hose can be cleaned with appropriate chemicals, hence reducing costs and extending service life.
One of the important factors taken into consideration while using a metal hose is that the external environment does not degrade it. Certain metal hoses are not electrically conductive and hence will not spark. Moreover, metal hoses will maintain their integrity up to 1200 degrees F even in the event of a fire. The metal hose has a higher vibration absorption than the non-metal hose, which minimises strain on connecting equipment.
The metal hose can withstand extreme temperatures. If the temperature of the material conveyed via the metal hose or the external temperature is too hot or too cold, the service life of a non-metal hose will shorten and collapse. You should keep your crew safe by using metal hoses that are flexible in low-temperature applications up to -50 degrees.
The corrugation in a metal hose helps it to retain full shape even under a full vacuum, while a non-metal hose will collapse under a vacuum even when reinforced. Metal hose is not recommended for applications of high pressure, but it is a supreme choice for vacuum applications.

The responsibility of job safety is an important aspect for any industry and a critical task to shoulder. Hence, it is vital to choose a metal hose that not only renders efficiency, but also the safety of the crew. Even when the application might not demand the use of a metal hose, the versatility of a metal hose will come in handy most of the time.
A metal hose is more efficient and durable compared to a non-metal hose. This makes it the primary choice for most industrial applications – be it restaurants, chemical plants, or factories.
