Stopper PRESS, 32

Product detailed description

Press stoppers are essential components in press-fit piping systems, particularly in heating and plumbing installations where secure and leak-free pipe terminations are required. These fittings are commonly used in residential and commercial buildings, including underfloor heating systems, central heating circuits, and domestic hot and cold water distribution. Installers working with ALPEX pipes will find press stoppers ideal for sealing pipe ends during system commissioning or maintenance. The compact design and robust materials ensure compatibility with press tools and long-term reliability in demanding environments.

Correct selection and installation of press stoppers are critical to system integrity. The stopper must match the pipe diameter and be compatible with the press tool type. Installers should ensure that the press tool is correctly aligned and that the stopper is fully seated before applying pressure. Any misalignment or improper seating can lead to leaks or system failure. The stopper should also be visually inspected for damage before installation.

The operating temperature of +120°C and nominal pressure of PN 10 make this press stopper suitable for a wide range of heating and plumbing applications. These parameters are essential for determining compatibility with system design specifications and ensuring long-term performance. The material selection, including nickel-plated brass and EPDM sealing, ensures resistance to corrosion and thermal expansion, which is crucial for maintaining a tight seal under varying operating conditions.Installation and connection The press stopper is installed using a compatible press tool. The stopper is inserted into the end of the ALPEX pipe, and the press tool is used to compress the sleeve and sealing ring around the pipe. The connection size is 32 mm, and the stopper is designed for use with ALPEX pipes of the same diameter. During installation, the installer must ensure that the stopper is fully seated against the pipe end and that the press tool is correctly aligned. Common installation mistakes include misalignment of the press tool, insufficient pressure application, and using a stopper with a damaged sleeve or sealing ring. These errors can compromise the integrity of the connection and lead to system failure.Compatibility and accessories This press stopper is specifically designed for use with ALPEX pipes and is compatible with press tools of types B, F, and TH. It is recommended to use the stopper with a press tool that is calibrated for the specified pipe and fitting combination. No additional accessories are required for installation, but it is important to ensure that the press tool is in good working condition and that the stopper is not damaged. Related products include other press fittings and tools from IVAR, which are designed for use in similar applications.Technical background for designers The press stopper operates by compressing a stainless steel sleeve and EPDM sealing ring around the ALPEX pipe. This creates a mechanical and hydraulic seal that prevents leakage. The nickel-plated brass body provides corrosion resistance and durability, while the EPDM sealing ring ensures flexibility and compatibility with thermal expansion. The stopper is integrated into the system by pressing it onto the pipe end, and its performance is influenced by the quality of the press tool, the condition of the pipe, and the accuracy of the installation. Proper system design should account for the thermal expansion of the pipe and the mechanical strength of the press connection to ensure long-term reliability.Service and operation Once installed, the press stopper requires no regular maintenance. However, it should be visually inspected during routine system checks for signs of damage, wear, or leakage. If any issues are detected, the stopper should be replaced immediately. There are no scheduled service intervals for this component, as it is designed for long-term use under normal operating conditions. In the event of system failure, the stopper should be removed and replaced with a new unit to restore the integrity of the connection.Frequently asked questions

Can the press stopper be used with other types of pipe besides ALPEX?
No, this press stopper is specifically designed for use with ALPEX pipes and is not compatible with other pipe materials or systems.

Is it possible to reuse the press stopper after installation?
No, once the stopper has been pressed onto the pipe, it cannot be removed or reused without damaging the sealing ring or sleeve.

What press tool types are compatible with this stopper?
The stopper is compatible with press tools of types B, F, and TH. It is important to use the correct tool to ensure a secure connection.

Can the stopper be used in systems with higher operating temperatures?
No, the maximum operating temperature is +120°C. Use in systems with higher temperatures may cause the sealing ring to degrade and compromise the connection.
