Internal - external thread

This category includes stainless steel braided flexible gas hoses with internal and external thread connections. These hoses are designed for safe gas transmission to heating boilers, stoves, and other gas appliances. The flexible design allows for easy routing and installation in tight spaces while maintaining a secure connection. All products are antistatic and meet safety standards for gas supply systems.

Available in various lengths and thread sizes, these hoses are suitable for both residential and commercial gas installations. The internal thread connects to the appliance, while the external thread fits into the gas supply line. The stainless steel braiding provides durability and resistance to corrosion and mechanical stress.

How to choose

• Select the appropriate thread size (e.g., 1/2" or 3/4") to match the appliance and supply line connections.
• Choose the correct hose length based on the distance between the gas supply and the appliance (e.g., 30–60 cm, 50–100 cm, or up to 2000 mm).
• Ensure compatibility with the system pressure and gas type (e.g., natural gas or propane) to avoid performance issues.
• Verify that the hose is antistatic and certified for use in gas supply systems to ensure safety and compliance with installation standards.
