MDT Tubing
Medium-Duty, Polyolefin
Data Sheet
Product Description
3M
™
MDT Tubing offers increased
flexibility in combination with excellent
abrasion, corrosion and environmental
resistance properties and meets MIL-
DTL-23053/15, Class 2.
Uncoated product (without sealant)
is available on special order. 3M MDT
medium-duty tubing is designed to
provide reliable performance as well as
excellent mechanical and environmental
protection. These flame-retardant
products combine the important
advantages of easy handling and
installation with maximum operating
reliability and system protection.
MDT comes with a factory-applied
sealant. This sealant is a heat-activated
thermoplastic material that remains soft
and flexible over long periods under
adverse environmental conditions.
During heating the sealant softens, bonds
to underlying surfaces and fills small
voids that might be present. When cool,
the sealant forms a barrier against water,
moisture, dirt and other environmental
contaminants.
Standard Colors
All sizes available in black. MDT-0400,
-0800 and -1100 are also available in red.
Standard Packaging
Four-foot lengths. Other lengths are
available subject to special quotation.
Ordering Information
Order MDTTubing by product name,
size equivalent to the expanded inside
diameter, package type and color. Always
order the largest size that will shink
snugly over the component to be
covered.
Example: MDT-1100-48A, 4 ft., black.
Typical Applications
MDT Tubing installs easily and has
shrink ratios to accommodate effective
insulating and sealing over large
transitions, splices and battery cables.
