Abstract
An integrally threaded brass insert is molded into the discharge conduit of a condensate pan such that a steel drainage pipe can be threadably engaged to the insert without causing damage to the plastic discharge conduit. Bonding between the insert and the surrounding conduit is enhanced by providing a knurled surface on the outer periphery of the insert.
