The AnvilStar Tri-Flex Loop is the only flexible pipe loop that absorbs and compensates pipe movement in six degrees of freedom (three coordinates axes, plus rotation about those axes simultaneously.)
The patented multi-plane movement design make the AnvilStar Tri-Flex Loop the safest and most reliable means of absorbing movement resulting from random seismic shifts in a fire protection system.
AnvilStar Tri-Flex Loop manufactured with a 4:1 safety factor.
