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 Tubing
Medium-Duty, Polyolefin
Data Sheet
M D T 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
c o n t a m i n a n t s .
Typical Applications
M D T Tubing installs easily and has
shrink ratios to accommodate eff e c t i v e
insulating and sealing over lar g e
transitions, splices and battery cables.
Standard Colors
All sizes available in black. MDT-0400,
-0800 and -1100 are also available in red.
Standard Packaging
F o u r-foot lengths. Other lengths are
available subject to special quotation.
