ABSTRACT:
A quick-connect coupling for a household faucet or the like and comprising a nipple and a fitting, features an improved seal which is a resilient annulus including a band portion adapted to seal against the inside of the fitting, a wing portion extending down from the top of the band portion and an end portion on the distal end of the wing portion, the end portion including an inward rib. Preferably the rib comprises an inwardly and upwardly facing quarter round, the underside of the end portion being inclined upwardly and outwardly when the fitting is installed on the nipple, whereby the water pressure forces the end portion inward to enhance the seal.
