These are male or female cylindrical reels which are fitted with a flange at one end in order to connect to any other unit by means of a pull-ring one-part and smooth at the other end.

Two versions are manufactured in the "MULTIFORM" system: male and female – and both are for general application in practically all installations, thus facilitating the connection of existing tubes to tubes with pull-rings one-part.

Male cylindrical hose connections are usually used at the end of the line as a connecting unit between the gates and the flexible hoses which connect the fixed or moving machine heads to the rigid metallic tubing network. They are normally connected to the inside of the heads.

Female cylindrical hose connections are usually used as part of the starting system of the installation, and are either welded or overlapped on the outside of the machine outlet hose connections in order to facilitate the initial assembly of tubing sections with a pull-ring one-part system.
