QUICK-CONNECT COUPLING HAVING IMPROVED SEAL ABSTRACT OF THE INVENTION 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 in- ward rib. Preferably the rib comprises an inwardly and upwardly facing quarter round, the underside of the end portion being in- clined upwardly and outwardly when the fitting is installed on the nipple, whereby the water pressure forces the end portion inward to enhance the seal. -1-
