EN14800 is a European standard that specifies the requirements for flexible metal hoses, metal hose assemblies and metal hose assemblies for gas installations. The standard specifies the design, performance and testing requirements for these types of hoses, including requirements for materials, dimensions, pressure ratings and temperature ratings.

EN14800 hoses are intended for use in gas installations, such as natural gas or liquefied petroleum gas systems, and are commonly used for residential, commercial and industrial applications. These hoses are typically made of high quality stainless steel or other metallic materials and are designed to be flexible, durable and resistant to corrosion and other types of damage.

EN14800 hoses are typically used to connect gas appliances to gas lines or to connect different sections of gas lines. They are known for their high pressure and temperature ratings, making them suitable for use in a wide range of gas installations.

When selecting an EN14800 hose, it is important to choose one that is compatible with the type of gas being used and to ensure that the hose meets all relevant safety and regulatory requirements. It is also important that the hose is properly installed and maintained to ensure safe and effective operation.
