Press bushing - external thread with O-ring, 1/2" M x 16

Product detailed description

Press bushings are essential components in heating and plumbing systems where rigid connections between plastic pipes and threaded fittings are required. This bushing is commonly used in residential and commercial buildings for connecting ALPEX pipes to internal-threaded components such as valves, radiators or manifolds. Installers working on central heating systems, underfloor heating or hot water distribution lines will find this fitting suitable for applications where a secure, leak-free connection is required under normal operating conditions.

When working with press bushings, it is important to ensure that the pipe is correctly prepared and that the pliers used are compatible with the fitting type. The press connection relies on the deformation of the stainless steel sleeve around the pipe, creating a tight mechanical and hydraulic seal. The O-ring ensures additional sealing against leakage, particularly in systems with thermal expansion or fluctuating pressure levels.

The operating temperature of +120°C and PN 10 pressure rating indicate that this bushing is suitable for systems with moderate thermal and hydraulic demands. These parameters are essential for sizing the fitting correctly to ensure it can withstand the conditions in the installation. The material selection, including nickel-plated brass and EPDM, ensures compatibility with hot water and heating fluids without degradation over time.Installation and connection The bushing is installed by sliding it over the prepared end of an ALPEX pipe and positioning it against the internal thread of the connected component. The stainless steel sleeve must be fully engaged with the pipe wall before pressing with compatible pliers of type B-F-TH. The press operation deforms the sleeve, securing the pipe within the fitting. The O-ring is compressed during this process, forming a secondary seal. It is important to verify that the pliers are correctly aligned and that the press stroke is complete to avoid under-pressing, which can lead to leaks or failure under pressure. Common installation mistakes include using incorrect pliers, failing to clean the pipe end or misaligning the bushing with the thread.Compatibility and accessories This bushing is specifically designed for use with ALPEX pipes and requires a compatible press plier of type B-F-TH for installation. The EPDM O-ring ensures compatibility with hot water and heating media. For complete installation, the system must include ALPEX pipes of the correct diameter and a suitable plier tool. No additional sealing materials are required, as the O-ring provides the necessary seal. This bushing is not interchangeable with other press fitting systems due to differences in sleeve design and plier compatibility.Technical background for designers The press bushing operates by mechanically deforming the stainless steel sleeve around the pipe, creating a rigid connection. The nickel-plated brass body provides corrosion resistance and durability in wet environments. The EPDM O-ring is chosen for its flexibility and resistance to thermal cycling, making it suitable for heating systems. The PN 10 rating ensures the fitting can handle typical pressures in heating and plumbing systems. The integration of this bushing into the system depends on the overall design of the piping network, including pipe diameters, flow rates and thermal expansion considerations. The service life of the fitting is influenced by the quality of the press operation, the compatibility of the plier tool and the operating conditions of the system.Service and operation No routine maintenance is required for this press bushing during normal operation. However, it is important to inspect the connection visually for signs of leakage or mechanical damage. If a leak is detected, the fitting must be replaced, as press connections cannot be re-pressed. The service life of the bushing depends on the quality of the initial installation and the operating conditions of the system. No specific service intervals are defined for this component, as it is designed for long-term use without maintenance.Frequently asked questions

Can this bushing be used with copper pipes?
No, this bushing is designed specifically for ALPEX pipes and cannot be used with copper or other pipe materials.

Is the O-ring replaceable after installation?
No, the O-ring is compressed during the pressing process and cannot be replaced without disassembling the fitting, which is not possible with a press connection.

Can this bushing be used in systems with higher pressure than PN 10?
No, the PN 10 rating defines the maximum allowable pressure for this bushing. Using it in systems with higher pressure may result in failure.

The fitting must be removed and reinstalled with the correct plier tool.
