Elbows - internal thread

This category includes 90° elbows with internal thread, specifically designed for gas systems. These fittings are used to connect ALPEX-GAS piping to external threaded components in heating and gas distribution systems. The elbows are suitable for use in environments with temperatures ranging from -20 °C to +60 °C and are commonly used in residential and commercial gas installations.

Each elbow is manufactured to ensure compatibility with standard gas piping systems and includes a stainless steel sleeve and HNBR sealing ring for durability and leak prevention. The fittings are suitable for nominal pressures up to PN 10 and PN 5 for continuous operation.

How to choose

• Select the correct internal thread size (e.g., 1/2", 3/4", or 1") to match the external thread of the connected pipe or fitting.
• Ensure the elbow is compatible with ALPEX-GAS piping and intended for gas applications as specified in PTN 704 05.
• Verify the operating pressure and temperature range (up to PN 5 and -20 °C to +60 °C) to confirm suitability for the installation conditions.
