Grooved Fittings & Couplings

Grooved fittings and couplings

Reliable grooved mechanical fittings and couplings designed for fire protection, sprinkler systems, and commercial mechanical piping applications.

Compatible with Victaulic-style grooved piping systems, these fittings provide dependable mechanical connections for commercial and industrial infrastructure projects.

Overview

"Grooved fittings and couplings provide a practical connection solution for piping systems that require efficient installation, secure sealing, and easier access for maintenance. They use mechanical couplings and fittings to connect pipes more quickly while allowing easier adjustments or modifications when needed.

These components are commonly used in:

  • fire sprinkler systems
  • mechanical fire protection infrastructure
  • commercial piping systems
  • industrial utility applications

Grooved systems help make piping installation faster and more flexible by minimizing the need for extensive welding or threading, while also supporting reliable performance and easier long-term maintenance."
