ABSTRACT:
A leak-tight non-contaminative joint, for connecting tin lined copper tubing with a tin lined coupling member, is formed by exposing the tin lining at the tube end and inserting an elastic "O"-ring between the exposed lining and the surrounding coupling, so that the fluid within the tubing and coupling does not contact any metal other than tin. A clamp for holding the coupling member and tubing together is also disclosed.
