End piece, 5/4" M; 40

Product detailed description

End pieces are essential components in the installation of pipe systems, particularly in applications involving hose connections. They are commonly used in residential and commercial buildings for water supply lines, heating circuits and irrigation systems. Installers often work with these fittings when connecting flexible hoses to rigid piping or appliances. The IVAR 853032040 model is specifically intended for use in systems with internal thread connections and is suited for environments where potable water compliance is required.

In such installations, the fitting serves as a secure and leak-proof transition between the hose and the threaded pipe. It ensures a stable hydraulic connection while maintaining the integrity of the system under operational conditions. The design allows for straightforward assembly and disassembly, which is beneficial for maintenance and replacement tasks.

Technical parameters

Installation and connection

Installation begins with verifying the internal thread size of the connected pipe. The fitting is designed for a 5/4 inch M internal thread connection, which must be matched precisely. Apply a suitable sealing compound or PTFE tape to the threads before tightening to ensure a watertight seal. Carefully align the hose and tighten the fitting using an appropriate wrench to avoid over-torquing, which can damage the brass material. After installation, perform a visual inspection for misalignment and a pressure test to detect leaks. A common mistake is using the wrong thread type or failing to clean the threads before assembly, both of which can lead to leaks or premature failure.

Compatibility and accessories

This end piece is compatible with standard hose fittings and internal-threaded pipe systems. It is typically used in conjunction with hoses of appropriate dimensions and sealing materials. Additional components such as sealing rings or thread sealants may be required depending on the system setup and local regulations. No related products are specified for this model.

Technical background for designers

The fitting operates by forming a mechanical and hydraulic seal between the hose and the threaded pipe. The CW617N brass material provides good corrosion resistance and mechanical strength, making it suitable for long-term use in potable water systems. The internal thread design ensures compatibility with standard piping components. The service life and efficiency of the fitting depend on correct installation, adherence to pressure and temperature limits, and the quality of the mating components. It is important to consider the thermal expansion of the system and the potential for vibration when designing the layout.

Service and operation

Regular inspection for signs of wear, corrosion or leakage is recommended during routine maintenance. No specific service intervals are provided in the technical data. To maintain performance, ensure that the sealing surfaces remain clean and undamaged. In case of suspected issues, disassemble the fitting and inspect the threads and sealing surfaces. Reapply sealing material if necessary and reassemble carefully.
