The Linsen Expanders are power-driven tools designed for making tubing connections without fittings. It enlarges the end of a tube, leaving .015-inch clearance for slip fit, so that another tube can be inserted and soldered like a sweat fitting. It is excellent for short bends, U-turns, copper, brass, aluminum, or thin steel tubing.

Wilson Long-Reach Expanders expand tubes at points far back from the tubesheet, such as the point at which it passes through a baffle sheet. Tube Outer Diameter: 58 to 412-Inch, 8 to 22 GaugeRoll length: 1 12 or 2 14-Inch and RelievedExtended reach: 6, 12, 18, 24, 30, 36, or 60-Inch

Easy to useOnly hand wrenches for insertion and withdrawalOverall length held short to operate in tight places

Wilson Captive Mandrel Tube Expanders enable tubes to be rolled where mandrel travel is limited because of restrictions in the tube Inner Diameter or when the tube bend is very close to the rolling area. For 38- to 2 12-Inch Outer Diameter tubesTo order a captive mandrel expander, provide us with the details of your specific application (tube Outer Diameter and Gauge, tubesheet thickness, and maximum mandrel travel)

True Up or Bring Pipe or Tube Ends to Round Wilson Pipe Sizing Expanders bring pipe or tube ends to a precise diameter to prepare them for soldering or brazing into sil-braz and similiar pipe fittings. Very close manufacturing tolerances ensure that rolls expand in a parallel manner. Features: For .435- to 12-Inch Inner Diameter pipe and tubesWhen ordering, specify tube Outer Diameter and Inner Diameter, tube metal and approximate depth of rolling.

The Series 41-A and 44-A Expanders were primarily designed for very small tubes as generally found on lubricating oil coolers and heat exchangers of similar characteristics. It features an adjustable ball bearing collar to meet the requirements of various thicknesses of tubesheets. The assembly comes complete with mandrel, rolls, cage, and collar with a flush (for 14-inch size) or 116 recess (for 38-inch size). NOTE: On selection of expanders, wall thickness of tubes run either nominally or minimum wall.

Available for 72 and 73 Series Expander. Allows rolling on far end where tubes project up to 3 inches. Order by basic "Thin Gauge Collar". Assembly no. and required dash no. 7300 for 1-Inch, 72000 for 2-Inch, and 7400 for 3-Inch.

Optional Collar Assembly used for rolling tubes too close to shell sides, divider plates, etc. to allow the greater diameter of standard collars to pass. Collars available from flush to 1516-inch recess for all tube expanders offered.

Thrust-bearing collar assembly is furnished on all Wilson Expanders up to 1-inch Outer Diameter tube sizes except 72 and 73 series 20-23 Gauge. Supplied with a 116-inch recess. Recesses up to 1516-inch available on special order.
