Flex hose is made to be more durable. It is made for divers to breath comfortably underwater. Flex hoses are being tested by the manufacturer before releasing it to the market. From the construction, flexibility, up to the packaging are all made by the manufacturer and rest assured that the hoses are well secured.

Purpose of Flex Hose for diving
SCUBA (Self Contained Underwater Breathing Apparatus) and SSBA (Submersible Breathing Apparatus) are the two most common types of underwater breathing devices used by occupational divers. Both mechanisms supply air to divers via flexible pressure hoses, but the types of pressure hoses utilized vary widely in terms of requirements and usage.
Hoses are being used to transport breathing gas from the cylinder’s oxygen supply to the regulator or inflator system via low pressure (LP) hoses, as well as to the pressure gauge via high pressure (HP) hoses. Interaction, recordings, illumination, electronics and/or heated water are typically bundled in umbilical. While in SCUBA, the hoses attach to an oxygen supply on the ground and then to the helmet or full face mask.
Importance of a Flex Hose
You can now breathe underwater, thanks to your flex hose. It is attached to your tank and delivers air to your mouth. A backup regulator is called an octopus. It typically has a longer hose and a bright yellow body to make it easier to find and use in an urgent situation.
It is important for every diver to have their own Flex hose (breathing apparatus) as well as an extra hose in case of emergency. There are a lot of different Flex hose from different brands. Each are designed to allow you to enjoy your diving activity without worrying how to breath.
Diving hose or Flex Hose important parts
A polymer hose is at the heart of each and every hose which is used to transfer and keep the gas within it. It must have a smooth inner lining for better airflow, but it will be fairly weak and will require the other layers for resilience. The inner core is likely the most significant layer to maintain, but it is also the most difficult to see. The core, like all rubber compounds, degrades and solidifies with age, eventually cracking or splitting. If water fills the hose at any point, it should be cautiously flushed out and dried out. Pressurized water can affect your regulator.
The mid-layer braided part is where your hose’s effectiveness and adaptability come from. This kind of material prevents the inner core from broadening while still allowing it to bend and flex as our hoses require.
The outer layer prevents the internal parts from destruction caused by the environment. Its external coating, which is typically made of a hard rubber, serves as a sacrificial template that absorbs scrapes and bruises while not interfering with the hose’s mechanism. Small openings can be found along the length of most hoses; these are intended to have as a security measure. Rather than ballooning and eventually bursting, the holes allow higher pressure to exit slowly and evenly down the length of the hose.
Precaution
Remember that all hoses will underperform at some point due to age, process conditions, or managing. Scuba hoses, regardless of brand or material, only needs minor maintenance. Allowing hoses to be exposed to direct sunlight for an extended period of time will greatly decrease the hose’s life. Do not try to rinse anything inside the hose with any type of solvent or other chemical; new hoses are factory hygienic. And if there is any reason to believe they are really not, the hose must be replaced. Always pressurize and inspect your hoses before each dive trip for mechanical damage, corroded fittings, bulges, and leaks.
Conclusion
In conclusion, Flex hose are made for divers to breath comfortably while under the water. It is a dive equipment that is thoroughly tested by the manufacturers. It must be replaced every five years. Its durability depends on how the user take care of his/her Flex hose or diving hose.
