Collection: 4.0" (102mm)

Mild steel electronic cutouts for 4.00 inch (102mm) pipe, slip-fit style — clamped over the pipe rather than welded in.

The 303540 single and the 303540D dual. Four inch is the largest in the mild steel slip-fit range and suits big-bore systems where a smaller cutout would be the restriction.

Size to the outside diameter of the pipe. Between two sizes, size down and use an adapter.
