Reduced nipples are essential components in heating systems where pipe sizes change between sections. This type of fitting is commonly used in residential and commercial buildings, particularly in boiler rooms and underfloor heating systems. Installers frequently use these fittings to adapt between different pipe sizes in steel-based heating circuits. The IVAR 25200262 model is suited for applications where a transition from 1 inch to 6/4 inch MM is required, ensuring a secure and leak-free connection.

These fittings are typically installed in systems where space constraints or design requirements necessitate a size reduction. They are often found in central heating systems, where they connect boiler outlets to distribution piping or in secondary circuits. The fitting must be selected based on the system’s hydraulic requirements and the compatibility of the connected components.

Technical parameters

Code	25200262
Brand	IVAR

The fitting is designed for a 1 inch male on one end and a 6/4 inch MM male thread on the other. This allows for a transition between different pipe sizes within a single system. The selection of this fitting depends on the system’s pressure and requirements, as well as the need for a secure and durable connection. The material ensures compatibility with standard components.

Installation and connection

Installation involves threading the fitting into the corresponding female connections on the 1 inch and 6/4 inch MM pipes. It is important to ensure that the threads are clean and free from debris before tightening. A sealing compound or PTFE tape should be applied to the male threads to prevent leaks. The fitting should be tightened evenly to avoid cross-threading or damage to the threads. Common mistakes include over-tightening, which can deform the threads, or under-tightening, which may lead to leaks over time.

Compatibility and accessories

This fitting is compatible with standard steel and copper piping in heating systems. It is typically used in conjunction with valves, radiators, and boiler connections. When installing, it is important to ensure that the connected components have the correct thread type and size. Additional components such as unions or isolation valves may be required depending on the system design.

Technical background for designers

The IVAR 25200262 is a brass fitting designed to provide a reliable transition between different pipe sizes in heating systems. The material’s resistance to corrosion and its mechanical strength make it suitable for use in wet and high-pressure environments. The fitting is integrated into the system by connecting it between two different pipe sizes, ensuring a continuous flow path. The longevity of the fitting is influenced by the quality of the installation, the system’s operating conditions, and the compatibility of the connected components.

Service and operation

Regular inspection of the fitting for signs of leakage or corrosion is recommended. If any issues are detected, the fitting should be removed and inspected for thread damage or wear. No specific service intervals are provided, but maintenance should be carried out as part of routine system checks. The fitting is generally low-maintenance and does not require frequent servicing under normal operating conditions.

Frequently asked questions
