Bouchon-réduit – 407 Pipe Fitting Customized

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
