Seismic Gator Joint

seismic-gato-combined-bg

In-line seismic expansion joint

Designed to protect engineered piping systems crossing a building’s seismic joint, the rugged Seismic Gator’s small profile makes it ideal for applications requiring a minimal footprint.

The Seismic Gator can be installed vertically or horizontally, and is maintenance free for the life of the piping system.

Designed and engineered to combine tried and true gimbal and bellows technologies with the rugged MetraGator expansion joint, the Seismic Gator is an extraordinarily strong, compact seismic expansion joint capable of handling high temperatures and pressures.
