How should I cut Siltek® / Sulfinert® / SilcoNert® 2000 tubing?
Cut the tubing ends with a standard metal tubing cutter. Point the tubing end down when cutting or reaming to prevent metal filings from depositing inside the bore.  Always flush tubing sections after cutting and end-cleaning to ensure the removal of metal or coating particles generated during cutting.

What is the solvent compatibility of Siltek® / Sulfinert® / SilcoNert® 2000 tubing?
Sulfinert®-treated tubing is compatible with a wide variety of solvents including methylene chloride, pentane, acetone, methanol, and water.  Avoid hydrofluoric acid and bases or strong hydrochloric acid solutions. These acids and bases will damage the Sulfinert® layer.
