Reducing tee 35x22x35 mm - thin-walled galvanized carbon steel, swaged PC5130 0352235

Application and Construction Characteristics

This component from the group of steel fittings is used to create branches in piping systems where it is necessary to connect a pipe with a diameter of 35 mm to a pipe with a smaller cross-section of 22 mm, while maintaining full flow in the main line. Thanks to the use of alloy carbon steel and pressing technology, the product eliminates the need for traditional joining methods such as welding or threading, which significantly accelerates installation and reduces the risk of human error. The entire assembly is made from a thin-walled profile, which, while maintaining mechanical strength, allows for material savings and easier installation in tight spaces.

A key aspect here is the diameter reduction – the 35x22x35 mm arrangement allows for connecting a smaller branch without the need for additional reducers or adapters, simplifying the system structure. All three openings are equipped with press-fit couplings, which require the use of a dedicated hydraulic or manual press tool for a permanent connection to the pipe. This mounting method guarantees leak-tightness based on EPDM seals (although the seals themselves are not listed as a separate item in the specification, their presence is standard for this type of coupling), resistant to typical heating and water media.

Strength and Operating Conditions

The material of manufacture – galvanized alloy steel – provides a solid barrier against corrosion in indoor environments. The raw surface after galvanizing is ready for installation without additional anti-corrosion treatment, which is important given the fast pace of installation work. This component does not have end caps or drain valves; it is a pure flow-diverting fitting.

It is worth noting the maximum working pressure, which is 16 bar at 20°C. This parameter is typical for central heating systems, domestic hot water systems, or low-pressure air conditioning systems. The built-in stop flange in the coupling structure prevents pipe movement during pressing and ensures proper positioning before the permanent connection. The lack of UL or FM certifications means that the product is intended primarily for European markets and does not meet specific American fire protection standard requirements for fire suppression systems, but it is standardly used in sanitary and heating installations in accordance with local building regulations.

Summary of Key Features

For the installer, this means a simpler work process:

• Quick installation: The pressing system allows for connection within a few seconds after proper measurement and cleaning of the pipe.
• Dimensional precision: Outer diameters of 35 mm (two openings) and 22 mm (one opening) are strictly defined, eliminating problems with fitting steel pipes of standard nominal diameters DN32/DN20 (depending on the pipe class).
• Connection durability: The galvanized steel construction guarantees longevity in dry or slightly damp technical rooms.
• Versatility: The "reducing tee" fitting is ideal where a smaller circuit (e.g., a radiator or draw-off point) needs to be supplied from a main collector with a larger diameter.

This product is a solid link in CONEX piping systems, combining the strength of metal with modern fire-free mounting technology. Its construction allows for flexible design of distribution networks where changing the pipe diameter is necessary for flow optimization or adaptation to existing infrastructure.
