Duraseal - Bullet Terminal

Duraseal Heatshrinkable
TE heat shrinkable pre-insulated nylon splices and crimp terminals provide reliable connections, especially where environmental sealing is important. Covering cable sizes from 0.5mm - 6.0mm², they are designed for use where water or condensation may be encountered, or where abrasion or mechanical abuse could be problematic. To complete a joint, the cable connector is crimped in the traditional manner, and the sleeving is then heated to shrink around the cable insulation. Special adhesive flows during the heating to seal the joint.
The TE Duraseal kit is especially suited for use in automotive (approved by most car manufacturers) and marine builds, where environmental sealing is important Kits are also available comprising various heat-shrinkable pre-insulated nylon splices and terminals, covering ranges from 0.5mm² to 6.0mm².
