End piece, 1" M; 20

Product detailed description

End pieces are essential components in the installation of flexible hose connections within plumbing and heating systems. They provide secure, leak-free interfaces between rigid pipe systems and flexible hoses, commonly found in applications such as domestic hot water distribution, underfloor heating loops, and industrial process circuits. Installers working in residential, commercial, and light industrial environments frequently use these fittings when connecting expansion vessels, circulating pumps, or heat exchangers.

During installation, the end piece is threaded into an internal female pipe fitting, ensuring a tight seal. It is important to ensure that the internal thread is clean and undamaged before tightening to prevent leakage. The CW617N brass construction provides good corrosion resistance and mechanical strength, making it suitable for long-term use in a variety of fluid conditions.

Technical parameters

The operating temperature limit of +120°C allows for use in hot water systems, while the PN 10 pressure rating ensures suitability for standard domestic and low-pressure industrial applications. These parameters are critical for correct sizing and selection to avoid performance issues or premature failure due to overloading.

Installation and connection

To install the end piece correctly, begin by cleaning the internal thread of the receiving fitting with a wire brush to remove debris or old sealing material. Apply a thin layer of thread sealing compound or PTFE tape to the male thread of the end piece. Carefully screw the end piece into place using hand tightening followed by a wrench for final tightening. Avoid over-tightening to prevent thread damage or distortion.

Key checks after installation include visual inspection for misalignment and confirming that all threads are fully engaged. A common mistake is using the wrong sealing method or applying excessive torque, which can lead to leaks or component failure. Always verify that the end piece is compatible with the hose and fitting material to prevent galvanic corrosion.

Compatibility and accessories

This end piece is intended for use with hoses and fittings that have an internal 1 inch thread. It is typically paired with flexible hoses equipped with corresponding hose ferrules and clamps to ensure a secure connection. Additional components such as sealing compounds, washers, or gaskets may also be required depending on the application and system design.

Technical background for designers

The end piece functions as a fixed connection point for flexible hose assemblies, transferring hydraulic loads from the hose to the rigid piping system. The CW617N brass material offers high tensile strength and resistance to dezincification, which is particularly important in potable water applications. The PN 10 rating indicates that the fitting is suitable for systems with moderate pressure levels and does not require reinforcement beyond standard piping practices.

The integration of the end piece into the overall system should account for thermal expansion and contraction effects, especially in hot water systems. The material’s thermal conductivity and coefficient of expansion must align with adjacent components to maintain system integrity over time. Proper alignment and support of the hose assembly will help reduce stress on the fitting and improve long-term reliability.

Service and operation

During operation, the end piece requires no active maintenance under normal conditions. However, periodic inspections should be carried out to check for signs of corrosion, leakage, or thread wear. If any of these issues are detected, the fitting should be removed and replaced. No specific service intervals are provided for this component, but regular visual checks are recommended during routine system maintenance.

Frequently asked questions

Is this fitting suitable for temperatures above 120°C?
No, the maximum operating temperature specified is +120°C. Exceeding this limit may result in material degradation and reduced performance.

What thread type is used for connection?
The end piece features a male internal thread sized for 1 inch, designed to connect to a corresponding female thread in the system.

Can I use a sealing ring instead of PTFE tape?
A sealing ring may be used if compatible with the thread size and system requirements. Ensure that the ring is properly seated and does not interfere with full thread engagement.
