Reducing Tee 35x28x35 mm - thin-walled galvanized carbon steel, swaged PC5130 0352835

Application and Construction of Steel Reducing Tee

This connecting component is designed to create branches in piping systems made of thin-walled steel pipes, where it is necessary to join three sections of different diameters. In this specific case, the configuration is 35 x 28 x 35 mm, meaning the tee connects two pipes with an outer diameter of 35 mm to one pipe with a diameter of 28 mm. This solution is dedicated to press-fit systems, eliminating the need for welding or threaded connections. As a result, installation is not only faster but, above all, cleaner and safer, especially in hard-to-reach locations or during work in confined spaces.

The material is alloy carbon steel, which has undergone galvanic or electrolytic zinc plating. Such surface treatment ensures corrosion resistance, which is crucial for the durability of water, heating, and ventilation installations. All three openings (connections) feature compression couplings with a stop flange, ensuring precise pipe centering during installation. The absence of gaskets in the traditional sense (the components are "raw" in the sense that no additional rubber inserts are visible externally, although sealing is achieved via rings inside the coupling) and the use of steel as the base material make the fitting highly resistant to mechanical damage and high pressures.

Key Operational Benefits and Performance Parameters

Selecting this reducing tee directly translates into the reliability of the entire piping network. Thanks to the press-fit technology, the connection achieves permanent tightness without the risk of loosening due to vibrations or temperature changes. This component is designed for operation at a working pressure of up to 16 bar at 20°C, meeting the requirements of most standard building installations.

The dimensional configuration allows for flexible pipeline connections: the main arms with a 35 mm diameter maintain the continuity of the main line, while the side arm with a 28 mm diameter enables branching to a smaller circuit without additional intermediate reducers. Inside the couplings, ethylene-propylene-diene monomer (EPDM) rubber gaskets are used, characterized by high chemical and thermal resistance, ensuring long-term tightness even with medium temperature fluctuations. Such a combination of materials – a steel structure and flexible sealing – defines the scope of applications in water, heating, and gas installations in accordance with system standards, while the press-fit coupling type simplifies on-site installation logistics.

Installation and System Compatibility

The installation process of this component requires the use of a dedicated hydraulic or manual press tool for the CONEX press-fit system. There is no room for errors resulting from under-tightening or threaded leaks – after proper pressing, the connection becomes an integral part of the pipe. The stop flange in each coupling acts as a depth limiter for pipe insertion, which is important for installers: simply push the pipe until it stops and perform the pressing at the marked location on the coupling.

This component does not have a drain valve or air vent – its role is solely the physical connection of three pipe sections at one point. As a result, it maintains low flow resistance and a compact design. This is a universal solution for professionals seeking a quick way to implement complex branches in steel installations, as well as for end investors valuing installation durability and safety without the need for regular inspections of mechanical joint tightness. The absence of UL or FM certifications does not indicate a lack of quality – the product meets rigorous European standards for galvanized steel piping systems used in general and technical construction.
