PVC (polyvinyl chloride) hose is generally not recommended for use with fire hoses because of its relatively poor fire resistance. In an emergency, fire hoses need to be able to withstand heat and flames in order to deliver water to the source of the fire and suppress it. PVC materials may melt or become very brittle at high temperatures, making them unsuitable for firefighting purposes.

Fire hoses are usually made of special fire-resistant materials, such as rubber or polyurethane, that maintain structural strength and durability at high temperatures to ensure they are effective in a fire.

Therefore, if you need a hose for firefighting purposes, it is highly recommended to purchase a hose specifically designed for firefighting to ensure safety and performance. Do not try to use regular PVC hose instead of fire hose, this may cause serious safety issues.
