Handhole Seat Cleaning Kit

Handhole Seat Cleaning Kit

Handhole Seat Cleaning Kit
(Part No. 9175-1)

The Wilson Handhole Seat Cleaning Kit includes all the tools you need to remove rust, deposits, torn gaskets and other encrustations from boiler drums, sectional headers, plug seats, handholes and pipe flanges. It is also suitable for the surfacing of corners, as well as flat areas of tanks, stacks and bulkheads, prior to painting.

  • Light rust and encrustation, a frequent cause of handhole leaks, are rapidly removed with the kit's special 2-inch diameter cup brush.
  • The air motor that comes with the kit readily converts to a powerful 1/4-inch capacity 4500 rpm drill.
  • The spindle and brush supplied with the kit clean drums and internals.
  • Expanding brushes can be used with the extension spindle to clean tube seat holes to insure optimum rolled joints.

Light rust and gasket encrustations, a frequent cause of handhole leaks, are quickly removed with the special Wilson Cup Brush. A smooth seat is produced up to the corner of the outerbore. The short bristle will not damage the seat.

Clean tube seat holes are essential to producing optimum rolled joints. Both the inside and outside of the drum or sheet hole, as well as the outside of the tube, must be cleaned. Expanding brushes may be used with the extension spindle furnished with the kit.
