Six-breakout heat-shrink boot

The 3M HDBB-605-1-250 is a polyolefin heat-shrink breakout boot with six outlets designed to seal and protect cable junctions in harsh environments. It suits installers who need a single-piece transition for multi-conductor bundles in automotive, industrial or marine wiring.

Semi-rigid abrasion-resistant wall

After shrinking the main body reduces from 2.39 in to 1.45 in while each breakout shrinks from .8 in to .35 in, leaving a .1 in wall that resists abrasion, acids and alkalis. The semi-rigid material stays flexible at -67 degrees F and retains integrity up to 230 degrees F, so the seal survives vibration and thermal cycling without cracking.

Replaces tape and separate glands

This boot replaces labour-intensive tape wraps or multiple cable glands when a harness splits into six legs. The jump is worth it when a permanent, flame-retardant seal is required and the 5.4 in installed length fits the available space.
