Here's the translation:Black elastomer reduction buffer Ø40 mm Nicoll
Soit 4.12 HT / unité
This black elastomer reduction seal from Nicoll allows you to connect a 40 mm diameter female PVC pipe to a metal pipe with a diameter between 12 and 40 mm. Made of flexible and durable elastomer material, it ensures optimal sealing and adapts to diameter variations. Its black color makes it discreet once installed. This versatile plumbing fitting is suitable for many applications in drainage or sewage systems.





















Features of the Nicoll Ø40 mm elastomer reducer cap
This black reducer cap made by Nicoll is designed to easily connect pipes of different diameters and materials. On one side, it connects to a 40 mm diameter female PVC pipe. On the other side, it can accommodate a metal pipe with a diameter ranging from 12 to 40 mm. This wide adaptation range is made possible by the flexible and deformable elastomer material, which perfectly conforms to the shape of the inserted pipe. Water-tightness is thus guaranteed regardless of the configuration.
Material and design
The cap is made of high-quality black elastomer. This material offers several advantages:
- Excellent elasticity to adapt to diameter variations
- Good mechanical and chemical resistance
- Perfect water-tightness thanks to its flexibility
- Long lifespan, does not degrade over time
Its black color makes it discreet once installed. The robust design ensures a reliable and durable connection between different plumbing elements.
Applications and advantages of the Ø40 mm reducer cap
This versatile reduction fitting finds many applications in drainage and sewage systems:
- Connecting a sink or washbasin to the main pipeline
- Junction between different sections of a drainage system
- Adaptation between PVC and metal pipes of varying diameters
- Quick repair in case of leakage on an existing fitting
Its main advantages are its ease of installation, great flexibility of use, and perfect water-tightness. It allows for simple connections that would be complex with classic rigid fittings.
Installation and maintenance
Installing this reducer cap is very simple. Just insert it onto the 40 mm female PVC pipe, then introduce the smaller diameter metal pipe into it. No specific tools are needed. The elastomer naturally adapts to any surface irregularities, ensuring optimal water-tightness. A simple regular visual check is sufficient to verify the good condition of the fitting over time. In case of a leak, replacement is quick and does not require any special plumbing skills.
