Protect your commercial, industrial, or institutional fire sprinkler systems against structural movement with the Metraflex Firevoop Grooved End Seismic Expansion Joint. This flexible joint installs directly into fire protection piping assemblies to absorb axial and lateral pipe movement, building settlement, and thermal expansion. By isolating vibration and accommodating seismic events, it prevents rigid pipe fracture and maintains system integrity when you need it most.
Engineered to satisfy NFPA 13 installation requirements for seismic protection, this assembly ensures your building stays compliant with critical life safety codes. The grooved-end design allows for quick, secure field installation using standard mechanical couplings, reducing labor time on the job site while delivering reliable movement accommodation.
