AMI / ARC MACHINE CASSETTES / COLLETS

For Tube and Pipe Orbital Welding Applications

We custom engineer aftermarket collets compatible with AMI. Read here to understand why our collets are improvements 

All our collets are made from 18-8 stainless steel to give you better wear over aluminum type collets.  

Our compliant grips  will hold oversize, undersized tubing and prevent maring.  The  500 heads now offer gate screws with springs to hold the latch up to make closing the upper gate easier. Our one-piece construction on the lower head will give you better alignment on both sides of your tubing.

AMI weld head compatible collets

Note: All Aftermarket collets are manufactured by Elite Industrial Sales and are not genuine Tri Tool, George Fisher, Orbitalum, AMI, Arc Machine or Swagelok products.  Each is a trademark of its own.
