Product Facts
3:1 and 4:1 shrink ratios
allow for connector-to-cable
sealing
Tubing environmentally
seals and protects
components and
interconnections
Medium wall provides
increased mechanical
protection
The adhesive in ATUM
tubing bonds to a wide
variety of plastics, rubbers,
and metals, including
polyethylene, aluminum,
steel, and copper
RoHS compliant
Applications Installation Operating Temperature Range
Environmentally seals and Minimum shrink -55C to 110C

tor sealing, breakouts, and
connector-to-cable transi-
tions. High expansion ratio
makes it possible to repair
most damaged cable jackets
without removing connectors.
