FireVoop Grooved End Seismic Joint for Fire Sprinklers | Metraflex

The Metraflex FireVoop™ Grooved End Seismic Expansion Joint is engineered to protect commercial fire sprinkler and suppression networks against pipe rupture and structural stress. Designed for integration into wet, dry, or preaction fire protection piping layouts, this compact V-loop assembly installs directly into the line to absorb multidirectional movement across X, Y, and Z axes. It prevents critical failure during seismic activity, thermal expansion and contraction, and ongoing building settlement.

This component satisfies the strict regulatory guidelines outlined in NFPA 13, which mandates comprehensive requirements for seismic bracing, flexible connections, and adequate pipe clearance to structural members. Utilizing this UL-listed expansion joint ensures code compliance and maintains the operational integrity of your life safety infrastructure.

• V-Loop Configuration: Features a compact footprint that fits tight spaces where traditional seismic loops cannot deploy.
• Multidirectional Movement: Accommodates movements in all directions (X, Y, Z), with configurations supporting movement ranges up to ±24 inches.
• Grooved End Design: Adapts to dynamic environments and provides fast, secure, and leak-proof connections.
• Pre-Assembled Units: Arrives 100% factory-tested and pre-assembled to reduce on-site labor time and installation costs.
• Stress Mitigation: Manages thermal growth, pipe expansion, contraction, and building settlement to extend system longevity.

Always verify local Authority Having Jurisdiction (AHJ) mandates and consult the manufacturer technical data sheets before beginning installation on site.
