DEISEL ENGINE
EXPANDER

Features
Designed for rolling injector sleeves into heads of diesel engines. These expanders are made to order for each application, and a detailed drawing of the injector sleeve and engine head is needed.



PR EXPANDER

Features
The rapid taper on mandrel allows full expansion of tube with minimum travel of mandrel. Mandrel is retained at rear of expander with nut to allow use near sharp tube bends.



STEP ROLLING
EXPANDER

Features
Ideally suited for faster tube rolling in tube sheets that are 10" and thicker without removing expander from tube. Expander cage has grooves spaced 1" apart and fitted with a spring- loaded, quick-spacing thrust collar that permits fast step rolling in 1" increments throughout full thickness of tube sheet.



"PST" PIPE
SIZING TOOL

Features
PST Series pipe sizing expanders are designed to true pipe ends, and to enlarge the pipe diameter to provide the correct clearance between the pipe O.D. and the I.D. of a fitting before making a silver solder or brazed joint. The threaded mandrel allows minute adjustments for accurate sizing of the pipe end.
