QUALTEK QRA3

HEAT SHRINK MEDIUM / HEAVY WALL TUBING - ADHESIVE LINED Qualtek Electronics
QR3, QRA3
HEAVY WALL POLYOLEFIN TUBING WITH OR WITHOUT
HOT MELT ADHESIVE
SHRINK RATIO 3:1
Features/Applications
QR3 has properties of excellent insulation, environmental sealing
and resistance to impact and abrasion. Designed for applications to
seal and protect electrical and communication connections.
Provides excellent mechanical protection to cable joints and
terminations. 3:1 shrink ratio allows it to easily fit over irregular
shapes and large connectors.
QRA3 is recommended for applications with light cable and wire
harnesses that require waterproofing and protection of connector
components and encapsulates and seals components within the
tubing.
