Performance Data


Parker Mineral Insulated MI Trace is designed for various temperature ranges including: Freeze protection and viscosity maintenance of 40°F
(4.4° C) to 80° F (26.7° C) at ambient temperatures down to -60°F (-51.1° C); and Process temperature maintenance of 120° F (48.9° C) to 170° F (76.7° C) at -60° F (-51.1°C) and 260° F (126.7° C) to 310° F (154.4° C) at 80° F (26.7° C).

Standard product has a Maximum Temperature Rating (MTR*) of 400° F (204.4° C). Higher temperature rated designs are available, please contact us.

*Maximum Temperature Rating is the maximum allowable temperature of the tracing fluid. Temperatures in excess of this may damage the product or alter its performance.



Analyzer, impulse and instrument lines; small diameter process lines; stack gas sampling lines; and utility lines.


Type 122 DHP Seamless Copper and 316/316L Welded and Seamless Stainless Steel, PFA, FEP and PTFE are standard. Wall thicknesses are available upon request, please contact us.

Heat Transfer Foil

An aluminum heat transfer foil for even heat distribution for precise temperature control.


Air-spaced, cross wrapped applied non-hygroscopic fiberglass thermal insulation for minimum heat loss.


The tough, black, 105°C rated, flame-resistant PVC (FR PVC) jacket, protects the tubing against corrosive atmospheres, water, oils, acids, alkalies, and most chemicals. Additional jacket materials are available upon request. For Material Specifications of jackets, please contact us.


Each tube in every length of Parker Mineral Insulated trace is pressure tested prior to shipment to assure the instrument engineer a high quality, reliable, trouble-free product. For Testing Specifications, please contact us.

NOTE: It is absolutely necessary to seal the ends against contamination from moisture and/or corrosive liquids. Neither Parker Hannifin and/or Motion & Flow Control Products, Inc. can assume any liability for product damage caused by moisture from unsealed ends.
