The Metraflex Fireloop seismic expansion joint for fire sprinkler systems is an extremely flexible joint accommodating large amounts of movement, providing excellent seismic protection, Metraflex says. It meets NFPA 13 guidelines and is UL listed and FM approved for movement in any direction, up to +/- 24”. It should be installed anywhere building or pipe movement is expected, including seismic and building settlement. Rated for use in both wet and dry systems, this seismic expansion joint is available in sizes 1” to 12” and can be used with the Seismic Breakaway Hanger to ensure complete freedom of movement, Metraflex points out.
