Underground UF Splice Kit

The Gardner Bender HST-1300 kit provides heat-shrink tubing for waterproof splicing of underground feeder cables. It accommodates wire sizes from 14 AWG to 18 AWG and is rated for 600V. The black tubing measures 8 inches by 1.3 inches in diameter and carries a UL listing. One bag is supplied per card.

Suited for direct-burial repairs

Electricians and property owners making permanent underground splices on UF cable will find the kit matches the required wire range and voltage rating. It is not intended for cables larger than 18 AWG or for installations exceeding 600V. Buyers needing connectors for thicker conductors or higher-voltage circuits should look elsewhere.

14 AWG to 18 AWG wire range

This specification defines the only cables the kit can safely join. Using it on wires outside this range voids the UL listing and risks water ingress. Confirm the conductor size before purchase.

Questions about this item

How can I verify the splice is watertight after heating the tubing?

After applying heat, the black tubing shrinks tightly around the UF cable and the adhesive lining bonds to the insulation, creating a continuous seal rated for 600 V direct burial.

What comes in the HST-1300 kit and what must I supply?

The carded kit includes the heat-shrink tubing and connector; you supply a heat gun or torch, wire strippers for 14 AWG to 18 AWG conductors, and the UF cable itself.

Which wire sizes does the HST-1300 accommodate?

The kit is designed for UF cables from 14 AWG up to 18 AWG, covering the range stated in the specifications.
