Reducing tee 28x18x28 mm - thin-walled galvanized carbon steel press-fitting PC5130 0281828

Application and Construction of Reducing Tee

This pipe system component is used to create branches in installations where pipes of different diameters must be connected. In this model, the main flow line maintains a diameter of 28 mm, while the side branch reduces to 18 mm. Such a configuration is typical for heating, sanitary, or ventilation systems, where fluid or gas flow must be adapted to smaller circuits without the need for additional reducing fittings.

The material of manufacture is carbon (alloyed) steel, which provides high mechanical strength and resistance to damage during installation. The entire surface has undergone galvanic or electrolytic galvanization. This is not merely an aesthetic issue – the zinc layer acts as a protective barrier against corrosion, which is crucial in environments with increased humidity or in contact with water. Thanks to this, the fitting is suitable for long-term operation in internal installations.

Mounting System and Operational Parameters

A key feature of this product is the use of a press-fit system. All three openings (two with a diameter of 28 mm and one with 18 mm) are equipped with crimp sleeves that require the use of a dedicated pressing head for permanent connection to the pipe. This method eliminates the need for welding or gluing, significantly accelerating the installer's work and reducing the risk of human error. The connection is leak-tight and durable after the first pressing cycle.

It is worth noting the maximum working pressure, which is 16 bar at a temperature of 20°C. This is a standard parameter for most water supply and heating installations in residential and public buildings. The "Tee" type construction, equipped with EPDM rubber seals, guarantees the hermeticity of the system even under pressure or temperature changes.

Benefits for the Installation and User

Choosing this specific model of reducing tee brings concrete benefits both at the installation stage and during subsequent operation:

• Fast installation: The press-fit system allows the connection to be made within a few seconds after pipe preparation (cutting, edge treatment). There is no need to wait for welds to cool or glue to dry.

• Corrosion resistance: Galvanized carbon steel handles moisture better than black steel, while at the same time being more durable than some plastic alternatives in mechanically loaded applications.

• Dimensional versatility: Connecting two 28 mm diameters with one 18 mm diameter allows for flexible routing of pipe runs without the need to purchase many different intermediate components.

• Connection durability: The crimp sleeve creates a mechanical connection that does not loosen as easily under vibrations or thermal cycles as traditional threaded fittings without proper sealing.

Thanks to precise surface treatment and compliance with standards for B/V profiles (thin-walled), this fitting forms a solid foundation for a reliable pipe installation. It is a solution proven in engineering practice, combining the strength of metal with modern fire-free mounting technology.
