Our Polypropylene Barbed to Female Luer Lock Adapters provide a convenient way to connect soft-walled tubing with products that feature a male luer slip or luer lock end. Each adapter has a lip to engage with the locking ring surrounding the mating male luer lock nose, for more secure connections; however, male luer slip style adapters can also simply press-fit into these adapters. Each adapter is manufactured from either polypropylene (for most aqueous solutions) or from Tefzel® (ETFE, for superior chemical resistance) and are packaged individually.
