PRESS-GAS elbow 90° - internal thread, 3/4" F x 26

Product detailed description

Gas distribution systems in residential and commercial buildings require reliable fittings to ensure safe and efficient operation. In such systems, elbows are used to change the direction of piping, especially in tight spaces or where the layout requires a 90° turn. This 90° elbow is specifically designed for use with ALPEX-GAS piping, which is commonly used in gas installations due to its flexibility and ease of installation. The internal thread allows for secure connection to external threaded components, making it suitable for use in gas supply lines, meter connections, and appliance feed lines.

When installing gas systems, it is essential to use fittings that meet the required pressure and temperature specifications. This elbow is suitable for environments where the operating temperature ranges from -20 °C to +60 °C, and it supports a nominal pressure of PN 10. These parameters are critical for ensuring the integrity of the system under normal operating conditions and during transient pressure spikes.

Technical parameters

Brand	IVAR

The nominal pressure rating of PN 10 indicates that the fitting is suitable for use in systems operating at up to 10 bar. The operating temperature range from -20 °C to +60 °C ensures compatibility with a wide range of installation environments, including cold storage facilities and heated buildings. These parameters are essential for selecting the correct fitting for the intended application and ensuring long-term system reliability.

Installation and connection

To install the 90° press elbow, the ALPEX-GAS pipe is inserted into the fitting until it reaches the stop mark. A press tool is then used to compress the fitting around the pipe, creating a secure and leak-proof connection. The internal thread allows for connection to external threaded components such as valves, regulators, or other fittings. It is important to ensure that the pipe is clean and free from debris before installation to prevent damage to the sealing surface. Common installation mistakes include over-pressing the fitting, which can cause deformation, or using the wrong type of press tool, which may not apply even pressure around the circumference of the fitting.

Compatibility and accessories

This elbow is compatible with ALPEX-GAS piping and is designed for use with internal threaded components. It is recommended to use it with clamping tools of type B for optimal performance. When ordering, ensure that the required number of fittings is available for the installation. Additional components such as straight press fittings, T-fittings, and valves may also be required depending on the system layout.

Technical background for designers

The operating principle of this elbow is based on the press-fit connection, which relies on the deformation of the metal fitting around the pipe to create a tight seal. The CW617N brass material provides good mechanical strength and resistance to corrosion, making it suitable for gas applications. The HNBR sealing material ensures a reliable seal under varying pressure and temperature conditions. When integrating this fitting into a gas system, it is important to consider the overall pressure drop, flow rate, and system layout to ensure efficient operation. The service life of the fitting is influenced by the quality of the installation, the operating conditions, and the maintenance practices followed.

Service and operation

No specific maintenance is required for this fitting during normal operation. However, it is recommended to periodically inspect the system for leaks, especially at connection points. If a leak is detected, the affected section should be isolated and the fitting replaced. There are no defined service intervals for this product, as it is designed for long-term use without maintenance.
