Gas hose inner - outer 1000 mm

Product detailed description

Gas hoses with inner and outer threading are commonly used in residential and commercial buildings to connect gas appliances to supply lines. Installers and technicians working on gas systems often require flexible solutions to accommodate misalignment or movement between components. These hoses are typically installed in kitchens, boiler rooms or utility areas where gas cookers, boilers or meters are located. The design allows for easy installation and removal during maintenance or replacement of equipment, while ensuring a secure and durable connection that resists mechanical damage and maintains system integrity.

When fitting gas appliances, the flexibility of the hose helps absorb vibrations or minor shifts in the installation, reducing stress on the pipe network. This is particularly important in systems where thermal expansion or structural movement can affect rigid piping. The hose ensures a reliable seal while allowing for some degree of axial and angular adjustment. It is essential to verify the correct thread configuration to ensure compatibility with the appliance and supply line fittings.

Technical parameters

Installation and connection

Before installation, confirm that the appliance and supply line have compatible internal and external threads. Use a clean cloth to remove any debris from the threaded ends. Apply a small amount of thread sealant to the male thread to enhance sealing, then hand-tighten the hose onto the fittings. After tightening, use a wrench to secure the connection further, taking care not to overtighten and damage the threads or sealing surfaces.

Ensure the hose is free from kinks or sharp bends that could restrict flow or cause stress points. Check that the hose is aligned properly and does not twist under normal operating conditions. After installation, perform a visual inspection and use a leak detection solution to test for gas leaks around the connections. A properly installed hose should allow for some flexibility without sagging or applying tension to the fittings.

A common mistake is using the wrong thread configuration, which can lead to poor sealing or failure to connect. Another issue is over-tightening the hose, which can deform the threads or compromise the integrity of the seal. Always follow the manufacturer’s guidelines for installation and ensure the hose is installed in a location that allows for regular inspection and access for future maintenance.

Compatibility and accessories

This hose is suitable for connecting gas appliances such as cookers, boilers and gas meters where a flexible connection is required. It is compatible with standard gas supply systems using 1/2 inch internal and external thread fittings. For installations involving non-standard or larger thread sizes, alternative hose models must be selected. No additional accessories are required for basic installation, but a thread sealant and wrench may be useful for ensuring a secure connection.

Technical background for designers

The hose consists of a flexible stainless steel tube reinforced with a metal braid made from stainless steel. The outer layer is covered with a protective plastic coating to prevent mechanical damage and provide a smooth surface for handling. The inner tube is made from rubber to ensure airtightness and resistance to gas permeation. The combination of materials provides flexibility, durability and resistance to corrosion and mechanical wear.

The stainless steel construction offers high tensile strength and resistance to deformation, making it suitable for environments where vibration or movement is expected. The hose can handle a range of gas types, including natural gas, propane and butane, without degradation. The design allows for integration into existing gas systems without requiring major modifications, making it a versatile option for both new and retrofit installations.

Service and operation

Regular inspection of the hose is recommended to ensure continued safe operation. Check for signs of wear, such as cracks, dents or abrasions on the outer casing, and verify that the connections remain secure and free from leaks. If any damage is detected, the hose should be replaced immediately to prevent potential gas leaks or system failures. No specific service intervals are defined for this product, but it should be replaced if it shows any signs of deterioration or if it has been subjected to excessive stress or exposure to harsh conditions.

Frequently asked questions

Can this hose be used to connect a cooker with an external thread to a gas supply with an internal thread?
Yes, the hose is specifically designed for this application, with internal and external threads matching the respective fittings on the appliance and supply line.

What is the difference between inner and outer threading in gas hoses?
Inner threading refers to a female thread on the hose end, while outer threading refers to a male thread. This hose has both configurations to allow direct connection to fittings with opposite thread types.

Is this hose suitable for all types of gas?
Yes, the hose is approved for use with natural gas, propane, butane and other common gas types used in heating and cooking applications.

How long can this hose be expected to last under normal conditions?
The hose has an indefinite lifespan when installed correctly and maintained regularly. However, it should be replaced if any physical damage or signs of wear are observed.
