MKS heater jackets are designed for use on stainless steel tubing and components. The cleanroom-compatible, CE compliant jackets are made with a unique molded design for proper fit and easy installation. Materials ensure consistent and uniform heating where the heater jacket comes in contact with the piping, while maintaining a safe, "warm to touch" temperature on the outside of the jacket. Snap-on flange insulators keep the flanges hot, eliminating cold spots.
