Swagelok Co. has introduced the multihead hydraulic swaging unit (MHSU) that properly pre-swages multiple sizes of fractional and metric Swagelok tube-fittings. Available in 1/2- to 1-inch and 12- to 25-mm, or 1- to 2-inch and 25- to 60-mm Swagelok tube-fitting sizes, the MHSU reduces makeup torque and installation time. The unit has interchangeable, corrosion-resistant stainless steel toiling and is available with a tube-marking feature that indicates when the tube is properly bottomed. www.swagelok.com Swagelok Co.
