Centering collar tightener
Fitted with thrust bearings
Two sizes; a smaller tightener with an adjusting wheel and a larger tightener with an adjusting crank.
Both tighteners fit all of our collar sizes, but we recommend using the larger tightener with collar size DN/NS 350 or larger because it has a 50 mm longer span and provides more torsional force. It is also better suited for thicker-walled pipes (max 6 mm).
