Threaded Loops

Threaded Loops have carbon steel male NPT threaded ends as standard.

As in other configurations of Seismic Loops, choose from either 2″, 3″ or 4″ of motion from center-line. For steam service, EFP recommends placing the loops in either an inverted or horizontal installation when conveying steam. A drain port should also be specified for steam service. We can also add an eyelet at the 90 degree elbow to accommodate a support rod or cable.
