Gas flexible hoses

Gas flexible hoses are essential components in gas distribution systems, providing adaptable and secure connections between gas appliances and supply lines. These hoses are commonly used in residential and commercial heating systems, cooking appliances, and industrial gas applications. Constructed from durable materials and designed for precise connections, they ensure safe and efficient gas flow while accommodating installation constraints and system movements.

How to choose

• Confirm the required connection type: internal thread (FF) for internal-to-internal (FM) or bayonet (RS) connections.
• Select the appropriate hose based on the maximum operating pressure (0.5 bar) and temperature resistance (up to +135°C or +120°C, depending on model).
• Verify compatibility with specific shut-off valves, such as IVAR.R4-T for dually insulated hoses.
• Ensure the hose material is stainless steel AISI 316 with a protective PVC coating for corrosion resistance and durability.
• Consider the application environment and whether the hose must withstand short-term high temperatures (up to +650°C for 30 minutes).

Frequently asked questions

What is the maximum operating temperature for these gas hoses?
Depending on the model, the maximum operating temperature is either +135°C or +120°C. Both can withstand short-term exposure up to +650°C for 30 minutes.

Can these hoses be used with any gas shut-off valve?
Some models, like IVAR.RT-E, are specifically designed for use with IVAR.R4-T bayonet shut-off valves and are not compatible with other types.
