There are two varieties of Luer Taper connections: Luer Lock and Luer Slip. Luer Lock fittings are securely joined by means of a tabbed hub on the female fitting which engages threads on the male fitting. Luer Slip fittings simply conform to Luer taper dimensions and are held together by friction. Luer components are manufactured either from metal and plastic and are available from many companies worldwide.
