## Long description

SiGMA-Li Kolano PP 25/90 K9025 is a polypropylene 90° elbow fitting with a 25 mm nominal diameter designed for creating right-angle connections in plastic piping systems. Intended for installations that use polypropylene components, this elbow provides a compact turn that redirects flow while maintaining the chemical and corrosion resistance properties of PP. Its smooth internal profile reduces flow turbulence and helps preserve hydraulic performance in water supply, heating circuits and general plumbing applications.
Advantages
The fitting is manufactured from polypropylene, offering resistance to corrosion, many chemicals and scale buildup compared to metal alternatives. Its standardized 25 mm diameter and 90° configuration enable predictable fitment with compatible polypropylene pipes and fittings. A compact design minimizes space requirements in confined installations, and the smooth internal surface supports steady flow with reduced pressure loss.
Suitable for
Residential and commercial cold and hot water supply systems
Heating circuit connections and radiator linkages
Plumbing runs in utility rooms, bathrooms and kitchens
Repair or modification of existing polypropylene piping networks
Key specifications
Material: polypropylene (PP)
Connection angle: 90° elbow
Nominal diameter: 25 mm
Application: plastic piping systems for water and heating
Internal profile: smooth to reduce turbulence
How to use
Prepare pipe ends by cutting square and deburring to ensure full insertion and a uniform joint. Depending on the chosen joining method for polypropylene systems (heat fusion, socket welding or compatible mechanical fittings), follow the appropriate installation procedure and tools specified for PP components. Ensure correct alignment at a right angle and allow cooling or curing time if fusion welding is used. After installation, inspect joints for leaks and verify system pressure according to project requirements.
Usage recommendations
Use this polypropylene elbow with pipes and fittings rated for the same service conditions and temperature range. Avoid exposure to aggressive solvents and open flames. For heated systems, confirm compatibility of joining method and pressure class with system design. When in doubt, consult installation standards or a qualified installer to ensure safe and durable connections.
