Reducing connector 42x28 - thin-walled crimped galvanized carbon steel PC5243 0422800

Diameter change in gas and water installations

This reducing connector is a key component for joining pipes of different diameters in press-fit systems. The product enables a smooth transition from a pipe with an outer diameter of 42 mm to a pipe with a diameter of 28 mm, which is essential when expanding installations or connecting devices with smaller connections. Thanks to the use of carbon steel and electro-galvanization, the fitting ensures corrosion resistance under typical operating conditions, and its design is adapted for press-fitting installation.

Construction and installation method

The fitting is manufactured as a one-piece element, eliminating the risk of leaks resulting from loose mechanical connections. One side features a crimping sleeve (connection 1), while the other has a push-in end (connection 2), facilitating adaptation to different pipe types within a single circuit. The presence of a stop flange on connection 1 ensures precise pipe positioning during pressing, which is crucial for joint durability. The entire assembly is made of alloy (carbon) steel, guaranteeing the mechanical strength required for pressurized installations. The product surface is coated with an electro-galvanic/electrolytic zinc layer, protecting against rust, while the press-fitting joining method allows for fast and clean installation without the use of fire or welding. The total length of 82 mm enables compact installation layout even in tight technical spaces.

Application and operating conditions

The product is intended for gas and water installations where tightness and resistance to a working pressure of up to 16 bar at 20°C are required. The absence of traditional seals (at the metal-metal contact point) and the use of steel make the fitting suitable for applications where other materials might degrade due to external factors or temperature. It should be noted that the product does not carry UL or FM certifications; therefore, its application is limited to standard building installations compliant with local standards for galvanized steel.

Thanks to its simple shape and the absence of eccentric elements, installation proceeds quickly without the need for additional auxiliary tools beyond a hydraulic or manual press dedicated to the B-Press Gas system. This is a solution for installers seeking proven steel components for gas systems, where safety and durability of the metal joint are the top priorities.
