Gas hose quick coupling - outer 1000 mm

Product detailed description

In industrial and residential settings, gas supply lines require reliable and durable flexible connections to accommodate movement and simplify maintenance. This stainless steel gas hose is commonly used in boiler rooms, kitchens, and industrial facilities where gas appliances such as cookers, boilers, and gas meters are installed. Installers often encounter situations involving axial stress, vibrations, or frequent disassembly during inspections and repairs. The hose provides flexibility while maintaining sealing integrity under operational conditions.

Flexible gas hoses are essential in piping systems where rigid connections would introduce stress points or hinder accessibility. They allow for slight misalignments between components and provide a secure link even when exposed to mechanical shocks or thermal expansion. The hose’s design ensures compliance with safety standards and facilitates safe handling during installation and servicing.

The hose operates up to a maximum working pressure of 0.5 bar, which is suitable for low-pressure gas systems. Its fire classification (B, -s2, d0) and resistance to temperatures up to 650 °C for 30 minutes make it suitable for environments with potential fire risks. The 1/2 x 1/2 connection size ensures compatibility with standard fittings. These parameters guide correct selection based on system pressure requirements and application environment.

Installation and connection

To connect the hose, align the male internal thread with the female fitting or valve body. Tighten the connection manually until snug, then use a spanner to apply a final quarter-turn. For the quick coupling end, insert the connector into the socket and twist to lock using the bayonet mechanism. Always verify that the coupling is securely engaged and that the locking tab is fully seated. Before commissioning, inspect the hose for visible damage such as cuts or deformations. Ensure the stainless steel braid is intact and the inner tube is free from blockages. Incorrect installation can lead to leaks or failure. Common mistakes include over-tightening the threaded end, which can damage the fitting, or failing to engage the quick coupling properly. Always follow the manufacturer’s guidelines for torque and alignment during assembly.

Compatibility and accessories

This hose is compatible with gas appliances featuring a 1/2 inch female quick coupling or internal thread. It works well with standard gas valves, regulators, and metering devices designed for low-pressure gas distribution. When ordering, ensure that all mating components have matching thread sizes and coupling types. Additional components such as isolation valves or pressure regulators may be required depending on the system configuration.

Technical background for designers

The hose consists of a flexible stainless steel core encased in a braided AISI 304L layer and a protective plastic sheath. The stainless steel construction resists corrosion and maintains structural integrity under repeated bending and movement. The quick coupling uses a plastic bayonet-style mechanism with a stainless steel male tip for secure engagement. This design minimizes exposure to contaminants and reduces the risk of accidental disconnection. The hose integrates into gas distribution systems by providing a flexible yet robust link between fixed infrastructure and movable appliances. Its fire resistance and antistatic properties enhance safety in high-risk environments. Long-term performance depends on proper installation, avoiding excessive bending or mechanical stress, and regular inspection for wear or degradation.

Service and operation

During routine maintenance, visually inspect the hose for signs of wear, corrosion, or deformation. Check the integrity of the stainless steel braid and the condition of the coupling mechanism. If any damage is found, replace the hose immediately. No specific service intervals are provided, but regular checks are recommended in accordance with local safety regulations. Always disconnect the gas supply before performing any inspection or replacement.

Frequently asked questions

Can this hose be used for propane or butane systems?
Yes, it is suitable for all types of gas including natural gas, propane and butane mixtures.

What is the maximum temperature the hose can withstand?
The hose is fire-resistant up to 650 °C for 30 minutes as per its classification.

Is it necessary to apply sealant or tape to the threaded end?
No, the internal thread is self-sealing and does not require additional sealing compounds.

How should the hose be stored when not in use?
Store the hose in a dry location away from sharp objects to prevent physical damage.
