Abstract
A screw-type draincock assembly in which separate body and stem parts are each integral elements and in which the body part provides an external seat and the stem part provides a transverse handle. The valve assembly is preferably formed by initially arranging a head portion of the valve stem to pass through the threaded bore and external seat of the body and, subsequent to assembly of the stem in the body, plastically flaring the head portion to a configuration adapted to seal the external body seat.
