In modern piping systems, having the right fitting makes all the difference between efficient flow and costly maintenance. One such essential component is the bouchon-réduit—a reduced end cap fitting commonly used to seal the end of a pipe while also adapting to a smaller diameter.
In this blog, we’ll explain what the 407 bouchon-réduit fitting is, its typical applications, customization options, and where to source high-quality versions directly from the manufacturer
🔧 What Is a Bouchon-réduit – 407 Fitting?
A bouchon-réduit (French for “reduced cap”) is a pipe fitting used to seal the end of a pipeline while simultaneously reducing the diameter of the flow path. It’s part of the 400-series fittings in many catalog systems, with the 407 model referring to a specific design standard.
This fitting is typically used in:
- PPR (Polypropylene Random Copolymer) pipe systems
- Hot and cold water installations
- Industrial or chemical pipelines
- Agricultural irrigation systems
