INTRODUCTION
The Master-Lee High Pressure Seal Cutter is designed to precisely cut the Swagelok ferrules from a flux thimble or
a stub on the Seal Table. Once attached to a thimble or stub the rotary cutting tool can be moved in .001” increments
to cut through the ferrule without causing damage to the sealing surface. The tool is equipped with adapters to use
on a Flux Thimble, 5/8” Diameter Stub, and 3/4” Diameter Stub.
