Abstract
A special fitting for installing a flanged nipple from the exterior of a duct. The threaded nipple has a handling stem formed integrally therewith, which is used to hold the nipple and flange inside the duct while a flexible cup seal washer is deformed and passed through the space between the handling stem and the duct. Thereafter, the fitting is drawn up with a nut and the handling stem cut off to provide a nipple.
