Auxiliary nipple 22 mm

Product detailed description

Auxiliary nipples are commonly used in residential and commercial heating and plumbing systems to ensure accurate pipe alignment and secure connections. Installers working on radiator heating, underfloor heating, or drinking water systems often encounter the need to reinforce cut pipe ends and create a smooth, safe surface for coupling connections. This stainless steel auxiliary nipple is specifically designed for 22 mm pipes and is compatible with HEPWORTH disassembly couplings, which allow for repeated assembly and disassembly during installation or system adjustments.

These systems are often used in new builds or renovations where flexibility in pipe layout is required. The use of polybutylene and copper piping is common in such applications, and the HEPWORTH coupling system ensures compatibility between these materials. The auxiliary nipple plays a key role in preparing the pipe end for a secure and leak-free connection, while also protecting against sharp edges that could damage seals or cause injury during installation.

The product is designed for a 22 mm pipe diameter and is made from stainless steel, which provides durability and resistance to corrosion. These parameters are essential for ensuring correct sizing and compatibility with HEPWORTH couplings. The stainless steel construction ensures that the pipe end remains stable and secure during installation and operation, while also supporting the internal jaw mechanism of the coupling.

Installation and connection

To install the auxiliary nipple, first ensure that the pipe is cut cleanly and the end is free from burrs or irregularities. Insert the stainless steel nipple into the pipe end until it is fully seated. This creates a smooth, uniform surface for the coupling to grip. The coupling is then placed over the pipe and tightened by hand until it is secure. No additional tools are required for this step, making the process quick and efficient. During installation, it is important to verify that the pipe is properly aligned and that the coupling is fully engaged. A common mistake is failing to seat the coupling correctly, which can lead to leaks or instability in the system. Always check that the internal jaws are gripping the pipe securely and that the coupling is tightened to the correct position. If adjustments are needed, the coupling can be easily disassembled using a special tool, the pipe removed, and the connection reassembled.

Compatibility and accessories

This auxiliary nipple is specifically designed for use with HEPWORTH disassembly couplings, which are compatible with both polybutylene and copper piping. It is suitable for use in radiator heating, underfloor heating, and drinking water systems. For a complete system, installers may also need to order additional components such as elbows, T-pieces, and other couplings to create the desired layout. The HEPWORTH system is fully disassemblable, meaning that components can be reused if adjustments are needed. This makes it ideal for installations where the final layout is not yet finalized. No additional tools are required for installation, and all components are designed to work together seamlessly.

Technical background for designers

The auxiliary nipple functions as a reinforcement and calibration tool for the pipe end. It ensures that the pipe maintains a consistent diameter and shape, which is essential for the coupling to grip securely. The stainless steel material is chosen for its strength and resistance to corrosion, making it suitable for use in both heating and water systems. The HEPWORTH coupling system uses an internal jaw mechanism to lock the pipe in place. This allows for a secure connection without the need for soldering or welding. The system is designed to be fully disassembled, which is particularly useful during the planning and adjustment phases of an installation. The use of polybutylene piping, which is compatible with the coupling system, ensures flexibility and durability in a wide range of applications. The oxygen barrier in the polybutylene piping prevents oxygen from entering the system, which helps to reduce corrosion and extend the lifespan of the heating system. This is especially important in closed systems where oxygen can cause long-term damage to components such as boilers and heat exchangers.

Service and operation

The HEPWORTH system requires minimal maintenance due to its durable materials and secure connection design. The stainless steel auxiliary nipple does not degrade over time and does not require replacement unless damaged. Regular visual inspections should be carried out to ensure that all connections remain secure and that there are no signs of wear or leakage. During operation, it is important to ensure that the system is properly balanced and that all components are functioning as intended. If a connection needs to be adjusted or replaced, the coupling can be easily disassembled and reassembled without the need for additional tools. This makes the system highly adaptable and easy to maintain over its service life.
