A plumbing connection wherein preformed tubes of a selected range of diameters cooperate with a connecting member having a passage of standard diameter. The tubes of all sizes in the selected range have tapered ends, each of whose outer small diameter portions is receivable in said passage and whose innermost large diameter portion is of a diameter greater than the diameter of the passage. Each tube carries slip nuts for pressing said tapered tube ends into circumferential sealing engagement with a connecting member when abutting the large end of a tapered tube portion and screw threaded on said connecting member.
