QUALTEK QR2

HEAT SHRINK MEDIUM / HEAVY WALL TUBING - ADHESIVE LINED Qualtek Electronics
QR2, QRA2
MEDIUM WALL, POLYOLEFIN TUBING WITH OR WITHOUT
HOT MELT ADHESIVE
SHRINK RATIO 3:1
Features/Applications
QR2 has properties of excellent insulation, environmental sealing and
resistance to impact and abrasion. Designed for applications to seal and
protect electrical and communication connections, providing excellent
mechanical protection to cable joints and terminations. 3:1 shrink ratio
allows it to easily fit over irregular shapes and large connectors.
3
QRA2 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.
Operating temperature: -55°C to +110°C
