ABSTRACT:
A compression sill-cock flange has a pipe coupling (1) with a flange (8) extended radially outward from a seal end (5). The pipe coupling (1) is straight-threaded internally from an attachment end (3) to a tapered sealing wall (4). The tapered sealing wall (4) is extended inward conically at a select angle from an inside circumferential periphery of the straight threading (2) to a circumferential coupling base (6) that is positioned in sliding contact with an outside periphery of a pipe (12) to which the pipe coupling (1) is attachable. The circumferential coupling base (6) extends to a desired position relative to the seal end of the pipe coupling (5). A set-screw orifice (9) with appropriate threading in a set-screw boss (10) can be provided on the pipe coupling (1). Use means are provided for use in relation to a double-tapered washer (14) and a sill cock (17).
