Elbow press 90° - male thread, 3/4" M x 20

Product detailed description

This press elbow is commonly used in domestic and commercial plumbing systems where rigid angular connections between ALPEX piping and threaded components are required. Installers typically find this fitting useful in central heating, hot water supply, and underfloor heating circuits. The elbow allows for directional changes in the pipework while maintaining a secure and leak-free connection. The design ensures compatibility with standard threading conventions and facilitates installation without the need for additional tools beyond the press unit.

The nickel-plated brass construction provides corrosion resistance suitable for long-term operation in environments with moderate chemical exposure. The press connection method ensures consistent sealing performance without relying on the installer’s manual tightening precision. The elbow can be integrated into both new builds and retrofit projects where space constraints limit the use of more complex fittings.

Technical parameters

Installation and connection

To connect the elbow to ALPEX pipe, first ensure the pipe end is clean and free from burrs. Insert the pipe into the elbow until it reaches the stop mark. Use a compatible press tool to apply uniform force around the circumference of the fitting. After pressing, verify the connection by checking for any visible gaps or irregularities. Confirm the press depth using the tool’s indicator to ensure correct engagement. Common mistakes include insufficient pressing depth, which leads to leaks, or over-pressing, which may damage the fitting or pipe wall.

The external thread dimension is 3/4 inch M x 20, meaning it connects to components with corresponding internal threading. Always verify thread direction and pitch match before tightening. When tightening the threaded side, avoid overtightening to prevent thread stripping or deformation of the brass body.

Compatibility and accessories

This elbow is specifically designed for use with ALPEX copper-aluminium composite pipes. It requires a press tool compatible with the IVAR press system for proper installation. For threaded connections, ensure that the mating component has a standard ISO metric thread matching the 3/4 inch M x 20 specification. Additional components such as straight couplings, unions or adapters may be needed depending on the layout of the system.

Technical background for designers

The elbow operates via a mechanical press connection, where the stainless steel sleeve compresses around the ALPEX pipe during pressing, forming a gas-tight seal. The nickel-plated brass body resists oxidation and maintains structural integrity over time. The EPDM sealing ring ensures flexibility and resilience against thermal expansion. Integration into the system should account for linear expansion compensation due to the metal-to-metal nature of the press joint. Longevity depends on avoiding excessive vibration, ensuring correct installation technique, and maintaining stable operating conditions within the specified limits.

Service and operation

During routine inspections, check for signs of leakage or corrosion, especially at the press zone and threaded interface. If any defects are found, replace the fitting immediately. No regular disassembly or lubrication is required for the press connection. Ensure that the system pressure and temperature remain within the rated PN 10 and T = 120 °C limits during operation.

Frequently asked questions

Can this elbow be used with copper or PEX piping?
No, it is designed exclusively for ALPEX composite pipes. Using it with other materials could compromise the integrity of the press joint.

Is it possible to reuse this fitting after disassembly?
No, once pressed, the fitting cannot be reused. Any disconnection requires replacement of the elbow to maintain system integrity and safety.

What press tool is required for installation?
A press tool compatible with the IVAR PT 5711 fitting system is necessary. Check the tool specifications to confirm compatibility with this model.

Can this elbow be used in steam systems?
No, the operating temperature limit of +120 °C does not permit use in steam applications where higher temperatures occur.
