ABSTRACT:
The disclosure relates to a tube coupling having a hollow tubular body having collet form couplings at either end thereof to receive and lock tubes in the body at either end. The body has an internal annular wall and an inner lines which extends over the wall shoulder and along the body to either side of the annular wall shoulder towards the locations of the collets. The liner is formed from a material which is inert to the fluid to be passed through the tubes and has integral annular seals to seal with the tubes inserted in the body to prevent loss of fluid from the tubes into parts of the body not covered by the liner.
