Fittings with nipple - male thread, 1/2" M x 20 x 2, ALU

Product detailed description

Threaded fittings with nipples are commonly used in residential and commercial building installations for connecting rigid and flexible piping systems. They are particularly useful in heating and plumbing applications where Alpex pipes are employed. Installers and technicians often use these fittings in underfloor heating systems, domestic hot water circuits, and central heating installations. The fitting allows for secure and leak-free connections between threaded components and Alpex tubing, ensuring reliable performance in pressurised environments.

When working with these fittings, it is important to ensure that the system pressure and temperature conditions align with the fitting's specifications. The fitting is designed for use in systems operating at up to 120°C and nominal pressure PN 10. These parameters are essential for selecting the correct fitting for the intended application and ensuring long-term system integrity.

Technical parameters

Installation and connection

Installation of the threaded fitting with nipple involves connecting it to a 1/2 inch external thread and inserting it into an Alpex pipe. The fitting includes an EPDM O-ring that ensures a watertight seal. Prior to installation, the threads should be cleaned and inspected for damage. The Alpex pipe should be cut cleanly and deburred to avoid interference with the fitting's insertion. After assembly, the connection should be checked for leaks by pressurising the system and observing for any signs of water or steam escaping.

Common installation mistakes include using incorrect thread sizes, failing to clean the threads, and not ensuring that the Alpex pipe is fully inserted into the fitting. These errors can lead to leaks or premature failure of the connection. It is also important to avoid over-tightening the fitting, as this can damage the O-ring or deform the brass body.

Compatibility and accessories

This threaded fitting is specifically designed for use with Alpex pipes (IVAR.TA). It is not compatible with other types of flexible or rigid piping unless specified in the manufacturer's documentation. When installing, it is necessary to ensure that the Alpex pipe is of the correct diameter and that the fitting is properly aligned with the threaded component. No additional accessories are required for standard installation, but it is recommended to have spare O-rings on hand in case of damage or wear.

Technical background for designers

The fitting operates by creating a mechanical and sealing connection between a threaded component and an Alpex pipe. The nickel-plated brass body provides corrosion resistance and mechanical strength, while the EPDM O-ring ensures a flexible and durable seal. The CW617N brass alloy is known for its good mechanical properties and resistance to dezincification, making it suitable for use in hot water and heating systems. The fitting is integrated into the system by threading it onto a pipe or valve and inserting it into the Alpex tubing. The service life and efficiency of the fitting depend on correct installation, proper system pressure and temperature conditions, and the absence of aggressive media in the system.

Service and operation

During operation, the fitting requires no regular maintenance. However, it is important to periodically inspect the connection for signs of leakage or wear. If a leak is detected, the fitting should be removed and inspected for damage to the O-ring or deformation of the brass body. In such cases, the fitting should be replaced. There are no specified service intervals for this product, as it is designed for long-term use under normal operating conditions.

Frequently asked questions

Can this fitting be used with other types of flexible piping?
It is specifically designed for Alpex pipes (IVAR.TA). Use with other types of piping is not recommended unless specified in the manufacturer's documentation.

What is the maximum operating temperature for this fitting?
The fitting is rated for operation at up to +120°C, making it suitable for hot water and heating systems.

Is it possible to replace the O-ring after installation?
Yes, the EPDM O-ring can be replaced if it becomes damaged or worn. It is recommended to replace the O-ring when disassembling the fitting for inspection or repair.

What should be checked during a system pressure test?
During a pressure test, the connection should be inspected for leaks. Any signs of water or steam escaping indicate a faulty seal and require the fitting to be reassembled or replaced.
