Elbow reducer 90° SiGMA-Li KR3225 PP 32×25 mm

SiGMA-Li KR3225 is a 90° elbow reducer in polypropylene (PP) with inlet and outlet diameters of 32×25 mm. Intended for plumbing and drainage systems, this fitting connects pipes of different diameters at a right angle, allowing a change of direction while reducing pipe size. Its polypropylene construction provides chemical resistance, light weight and suitability for both indoor and outdoor installations where corrosion resistance and durability are required.

Advantages

The polypropylene 90° elbow reducer offers corrosion and chemical resistance compared with metal fittings and resists common household and industrial fluids. Its reduced weight simplifies handling and installation, and the molded transition between 32 mm and 25 mm diameters ensures a compact, space-saving connection. The right-angle design enables precise direction change in tight installations without additional adapters.

Suitable for

• Domestic and commercial drainage systems
• Plumbing installations requiring diameter transition from 32 mm to 25 mm
• Vent and waste pipe routing where a 90° change of direction is needed
• Indoor and sheltered outdoor installations exposed to non-extreme chemicals

Key specifications

• Material: polypropylene (PP)
• Shape: 90° elbow reducer
• Connection diameters: 32 mm (inlet) × 25 mm (outlet)
• Application: plumbing and drainage
• Suitable for indoor and outdoor use (non-extreme conditions)
• Weight: lightweight construction for easier handling

How to use

Ensure pipes are clean and cut squarely before assembly. Fit the 32 mm end to the corresponding pipe and the 25 mm end to the smaller pipe, using the appropriate joining method for PP fittings (such as solvent cement or a compatible mechanical coupling) according to local plumbing standards. Align the elbow so that the 90° change of direction meets the system layout, and secure connections to prevent movement. If used outdoors, protect exposed joints from prolonged UV exposure if required by installation conditions.

Usage recommendations

Verify compatibility of joining methods and seals with polypropylene material and the transported media. For installations carrying aggressive chemicals or operating under high temperature or pressure, consult technical guidelines to confirm suitability. Adhere to local plumbing codes and best practices for connection strength and accessibility for maintenance.
