SST and AST provide a simple, positive splice-sealing method
that offers protection under adverse environmental conditions.
Tubing supplied with standard sealant provides water sealing
and environmental protection in wet or underground applica-
tions. The thermoplastic adhesive not only seals, but also pro-
vides mechanical strain relief. The polymer tubing has excellent
insulating, abrasion-resisting, and strain-relief properties.
Features/Benefits

Strain relief.
•
Waterproofing.
•
Thick-wall insulation and abrasion-protection.
•
No need for greases, tape, or epoxy.

place of asterisk* substitute length of tubing to be ordered. For example, SST*-11, as the third column indicates, comes in 6-, 9-, and 12-inch lengths, so 9-inch SST tubing would be
SST 9-11. The suffix M = medium-wall tubing.
