• Weep holes allow instant leak detection.
• Unique ferrule action helps prevent excessive deformation of the seal area of tube end and body.
• Fitting does not reduce tube wall thickness.
• Fittings can be made, disconnected, and remade easily to provide a reliable leak-tight seal.

Options and Accessories

Pre-Setting Tool
The pre-setting tool is suggested for initial assembly of Swagelok high-pressure tube fittings when used with annealed tubing. The pre-setting tool must be used for initial assembly of these tube fittings when used with Swagelok hardened tubing.

Coning Tool
High-pressure tubing used with Swagelok high-pressure tube fittings should be prepared with a Swagelok coning tool. The Swagelok coning tool cuts a smooth, concentric cone on the tube end to help ensure reliable sealing in the fitting body. It is designed to prepare 1/4, 3/8, and 9/16 in. outside diameter heavy wall tubing. Each coning tool comes in a carrying case with Rapid Tap™ cutting lubricant; 1/4, 3/8, and 9/16 in. collets and tool bits; and inside-diameter deburring tool. Replacement parts are also available.

Pre-Coned Tubing
Pre-coned tube lengths of hardened or annealed tubing are available from 2 to 120 in. (5 to 305 cm) in length. Tube lengths are precisely coned with a high-quality finish. Annealed tubing is rated to 30 000 psig (2067 bar). Hardened tubing is rated to 60 000 psig (4134 bar).
