摘要

The tubular tool for use in effecting a gas exchange in multiplate insulating glass units provided with a sealant spacer has a sharpened end (1) like a plug drill and is provided with a handle portion (2) at the other end. The handle portion (2) has a port (3) for connection to a device which exchanges gas in a space between glass plates of the insulating glass unit. The wall of the tubular tool (20) is provided with throughgoing openings (4) in a portion between the sharpened end (1) and the handle portion (2). The tubular tool also can have a portion without throughgoing openings having a length approximately equal to a thickness of the sealant spacers both at the sharpened end and at the handle portion.
