Flexible gas hose 1/2" FF 75-150 cm

Product detailed description

This flexible gas hose is commonly used in residential and commercial gas installations to connect indoor gas appliances to supply lines. It is suitable for use in kitchens, utility rooms, and other indoor environments where a flexible connection is required between two threaded fittings. The hose allows for minor misalignments and simplifies installation by accommodating slight positional adjustments. It is designed for use with natural gas or propane and is intended for indoor applications only.

The hose is frequently used in domestic and light commercial settings, such as connecting gas stoves, water heaters, or boilers to the main gas supply. It is ideal for installations where rigid piping is impractical or where flexibility is needed to ease installation or accommodate thermal expansion. The hose is not suitable for outdoor use or for high-pressure industrial applications.

Technical parameters

Installation and connection

Installation of the flexible gas hose requires ensuring that both ends are connected to compatible 1/2 inch female-threaded fittings. The hose should be cut to the required length using appropriate tools, and the cut ends should be cleaned before threading. A suitable wrench or spanner is required to tighten the connections securely. It is important to check that the hose is not kinked or damaged during installation, as this can restrict gas flow or cause leaks. Common installation errors include over-tightening the fittings, which can damage the threads, or under-tightening, which can lead to gas leakage.

Compatibility and accessories

This hose is compatible with standard indoor gas appliances and supply lines that use 1/2 inch female-threaded connections. It is intended for use in systems where both ends of the connection are threaded. No additional fittings are required if the existing system already has matching threads. However, if the system requires different thread types or sizes, appropriate adapters or conversion fittings must be used. Related products such as gas regulators, pressure gauges, or shut-off valves may also be required depending on the system configuration.

Technical background for designers

The hose operates as a flexible conduit for gas, allowing for movement and minor positional adjustments while maintaining a secure connection. It is constructed from materials that resist gas permeation and are suitable for indoor use. The FF thread configuration ensures a secure and leak-tight connection when properly tightened. The hose's flexibility is achieved through a coiled or corrugated internal structure, which allows it to bend without kinking. The service life and efficiency of the hose depend on correct installation, avoiding excessive bending or mechanical stress, and ensuring compatibility with the gas type and system pressure.

Service and operation

Periodic inspection of the hose is recommended to ensure that there are no signs of wear, corrosion, or damage. The connections should be checked for tightness and signs of leakage. If the hose is cut during installation, the cut ends should be inspected for burrs or irregularities that could affect performance. No specific service intervals are provided in the technical data, but it is advisable to replace the hose if it shows signs of degradation or if the system is being modified or upgraded.

Frequently asked questions

Can this hose be used for outdoor gas connections?
No, this hose is intended for indoor use only. It is not suitable for outdoor environments or for exposure to weather conditions.

What tools are needed to install this hose?
A suitable wrench or spanner is required to tighten the threaded connections. A cutting tool may also be needed to adjust the hose length to the required size.

Can this hose be used with both natural gas and propane?
Yes, the hose is suitable for use with both natural gas and propane in indoor applications, provided the system pressure and other requirements are compatible.

Is it possible to extend the hose beyond 150 cm?
No, the hose is available in a maximum length of 150 cm. If a longer connection is required, an additional section or a different hose type should be used.
