FBC System Compatible

Compact Profile

The compact design and thin profile of the FireLoop seismic joint helps keep installations running tight and minimizes the impact on designs.

360° movement

Incredibly flexible, the FireLoop seismic expansion joint comes in sizes that can accommodate up to ±24 inches of pipe movement.

Low pressure loss

The FireLoop seismic expansion joint for fire sprinklers

The Metraflex® Fireloop® seismic expansion joint for fire sprinkler systems is an extremely flexible joint accommodating movement in all directions, providing excellent seismic protection. It meets NFPA 13 guidelines and is UL listed and FM Approved.

Available from Metraflex, the leader in seismic pipe protection, the Fireloop® expansion joint is capable of movement in all directions with 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 and FM Approved for fire sprinkler systems, the FireLoop has the unique ability to handle movement in all directions, bringing the same seismic protection offered in the regular Metraloop expansion joint to this critical, life-saving application. Extremely compact and requiring only one hanger and two connections, it simplifies sprinkler system design and eliminates the need for multiple, convoluted joints or grooved couplings fabricated on site. In addition, the FireLoop joints design offers lower pressure loss, significantly lower than other seismic joint configurations.

In seismic applications, the FireLoop is positioned anywhere movement is expected, such as the building's seismic joint. When the loop is installed vertically or horizontally, the 180-degree return bend of the loop requires just one hanger support to allow the entire FireLoop expansion joint to move freely.

Already installed in thousands of seismic applications for fire sprinkler systems, the FireLoop expansion joint is significantly more compact than grooved pipe loop arrangements.
