Reducing sleeve KZ/KW PVC-U 1 1/4"x1" 437-168

PVC-U Reducing Sleeve – Reliable Connection in Installations

Reducing sleeve KZ/KW made of PVC-U is an element connecting pipes of different diameters, ensuring the tightness and durability of the installation. Designed for piping systems built to the inch (IPS) standard, it corresponds to the dimensions of steel pipes, making it easier to modernize existing installations. Made of high-quality polyvinyl chloride, it guarantees resistance to corrosion and the action of many chemical compounds.

Application and product features

The 1 1/4" x 1" reducing sleeve is used in cold water, air conditioning and industrial installations where resistance to aggressive media is required. Its construction allows for a glued connection of pipeline elements, providing a secure and durable connection. The white color makes it easier to identify in the system. The outer diameter of the sleeve is 42.1 mm.

• Versatility: Ideal for connecting pipes of different diameters in PVC-U systems.
• Durability: PVC-U material ensures a long service life of the installation – estimated at a minimum of 50 years.
• Chemical resistance: Resistant to the action of several hundred chemical compounds, making it ideal for industrial applications.
• Hygiene: Physiologically and microbiologically inert allows for use in drinking water installations.
• Easy installation: Glued connection does not require specialized tools or electricity, which speeds up and reduces installation costs.
• Flow resistance reduction: The fitting design minimizes local flow resistance, ensuring optimal medium flow.
• Insulation: High thermal insulation reduces condensation of water vapor on the surface of cold water pipelines.

Construction and material properties

The polyvinyl chloride (PVC) used is characterized by a low weight compared to traditional materials (metal), which facilitates transport and installation. The smooth inner surface of the pipes reduces flow resistance, and excellent fire-resistant properties (does not support combustion) increase safety. In addition, PVC provides electrical insulation, eliminating the risk of galvanic and electrochemical corrosion – particularly important in underground installations. There is no oxygen diffusion through the material, which is important for protecting against internal corrosion of pipelines.
