HOLE-CUTTING
The hole-cut method of pipe preparation is required
when using mechanical tees, mechanical crosses, and
saddle -lets. The method of pipe preparation requires the
cutting or drilling of a specified hole size on the centerline
of the pipe. Always use the correct hole saw size as shown
in this catalog and never use a torch for cutting a hole. After
the hole has been cut all rough edges must be removed and
the area within 5/8’’ (16mm) of the hole should be
inspected to ensure a clean smooth surface, free of any
indentations or projections that could affect proper gasket
sealing. The area within the “A” dimension should also be
inspected and must be free of dirt, scale or any
imperfection that could affect proper seating or assembly
of the fitting.
