HEAT SHRINK MEDIUM / HEAVY WALL - ADHESIVE LINED
QRS
MEDIUM WALL, POLYOLEFIN TUBING WITH BLACK MASTIC SEALANT
SHRINK RATIO 3:1
Features/Applications
QRS tubing is mastic lined heat shrinkable tubing designed specially for protecting
metal pipe joints, soil nails and any other connectors requiring environmental
sealing. The radiation cross linked jacket provides effective mechanical protection
and mastic layer provides excellent water and moisture proof.
