Upchurch Scientific® LuerTight fittings are specifically designed to connect semi-rigid fluoropolymer tubing without barbs or nuts. By integrating ferrules into the luer bodies, LuerTights will reliably hold your fluoropolymer tubing in place while giving you the convenience of a luer connection - a great improvement over barbed luer connections. An inline set of LuerTight fittings provides a quick and easy disconnection option. LuerTight connections are also less bulky and more economical than nut-to-luer style fittings.
The bodies of these products are manufactured from polypropylene and the ferrules (separate ferrules not used with the P-831) are made of Tefzel (ETFE). Each LuerTight fitting conforms to ISO requirements for medical luer taper configuration and performance (45 psi/3.1 bar).
