Product Description

FireStrait compensates for pipe offset and lateral movement.

The new FireStrait by Metraflex accommodates pipe offsets and lateral movement anywhere along your fire sprinkler piping system. Accomodate pipe offsets at odd angles and avoid labor costs associated with cutting fittings at difficult or small angles. Offsets ranging from 0 to 180 degrees are easily managed with the FireStrait flexible connector.

Utilize the same flexible technology as our Fireloop seismic expansion joint to absorb movements ranging from 1/8” offset from minor vibrations all the way up to +/-60” offset due to large mechanical movements such as mobile racking and floating dock connections.

Available in grooved and flanged, and threaded end-fittings, FireStrait connectors come in sizes ½” through 12” with galvanized end-fittings available upon request.

Product Highlights
  • Provide flexible connections to pipe offsets where odd connection angles or lateral movement is required.
  • UL Listed for use in fire sprinkler systems
  • Available in grooved, threaded, and flanged end-connections
  • Longer lengths availble for use on mobile storage racks and large mechanical movements
  • Flanged pump connector option available
