The 100% tested, pre-assembled, seismic ready joint. You know you’ll meet code. You know it will work.

The Metraflex® FireVoop™ seismic expansion joint for fire sprinkler systems. Great seismic protection when you need a different footprint to fit your design and installation location.

A little longer, with a different compact configuration, the FireVoop™ seismic joint has undergone the same rigorous UL testing as the Fireloop seismic joint. It is an extremely flexible joint accommodating movement in all directions, providing excellent seismic protection. And it meets NFPA 13 guidelines.

Available from Metraflex, the leader in seismic pipe protection, the FireVoop™ expansion joint is available in sizes able to accommodate movements up to ±24 inches. It should be installed anywhere building or pipe movement is expected, including seismic, thermal growth and building settlement.

UL listed for fire sprinkler systems, the FireVoop™ seismic joint has the unique ability to handle movement in all directions, bringing the same seismic protection offered in the Fireloop expansion joint to this critical, life-saving application.

• Seismic protection with a smaller footprint
• Can handle building settlement and thermal growth
• UL Listed in stock sizes from 2″ through 8″ diameter
• Available in movements up to +/- 24″
