Spring Sealed Drain Fitting Abstract of the Disclosure A drain fitting for bathtubs, sinks or the like has an annular body and a closure member which may be seated against the inlet end of a drain passage through the body. A stem extends from the closure member through a guide element within the drain passage and a spring acts between the stem and guide element to apply sealing pressure to the seated closure member. The closure member may be manually pulled outwardly from the body against the force of the spring and turned angularly to latch the member at an open position when fluid is to be drained. The positive sealing force generated by the spring minimizes or avoids leakage under conditions where the forces of gravity and pressure from overlying liquid may be inadequate for the purpose.
