摘要：#$%^&*AU2019100400C420200820.pdf> Abstract An O-ring-free plumbing fitting (10) comprising a hollow body (14) and a tubular engagement portion (12) opening to the hollow body (14) for engagement within a pipe. The tubular engagement portion (12) comprises a tapered distal end (16) for receiving the pipe and an arrangement of circumferential ribs (22) each of the same diameter between the tapered distal end portion (16) and a proximal end portion (18) of the tubular engagement portion (12). The arrangement of circumferential ribs (22) sealingly engages the pipe when the pipe is crimped on the tubular engagement portion (12) with a sleeve retaining member (6) and an overlying crimping sleeve (120). The arrangement includes at least one elongated flat circumferential rib (24) and at least one barbed circumferential rib (20, 26) on each side of each elongated flat rib. Each elongated flat rib (24) has a flat outer sealing surface with a length of at least 1.5 mm.
