Stainless steel
Stainless tubing is available in 1/32", 1/16", and 1/8" OD, in pre-cut or custom lengths.
Electroformed nickel
EFNi tubing is made by electroplating nickel over a diamond-drawn mandrel in a continuous process. The internal surface has a mirror-like 1-2 microinch finish, minimizing carryover potential.
