Heat Shrink Transition Boot for Cable Harness - Y / T / 2 3 4 Way

About Heat Shrink Transition Boot for Cable Harness - Y / T / 2 3 4 Way

Where a cable harness splits into branches, taped or tubed joints tend to crack, leak and look different every time. Gala's moulded transition boots give each branch point a fixed shape with mechanical protection, strain relief and sealing against dust and moisture.

Each transition is supplied expanded and shrinks with heat onto the main bundle and each branch. Shapes cover the common layouts: Y-type and T-type for two branches, Q-type with a side branch (including a 30-degree bifurcated version), 2-way boots for two parallel branches, E-type and 3-way boots for three branches and 4-way boots for four. The inner wall can be pre-coated with adhesive for sealing and waterproofing.

Boots are offered in three material grades: -10 semi-rigid fluid-resistant modified elastomer (-75 to 150 deg C, installs at 175 deg C), -20 semi-rigid flame-retardant polyolefin (-55 to 135 deg C, installs at 150 deg C) and -30 semi-flexible polyolefin (-42 to 105 deg C, installs at 150 deg C), with three adhesive options: -11 general-purpose hot melt, -22 high-performance hot melt and -33 epoxy.

Typical users are harness makers for defence, railway and public transport, commercial vehicles and industrial equipment. Sizes are chosen from the bundle diameter at the body end and at each branch, using the supplied and recovered diameters in the charts.

Supplied by Gala, India. Datasheet and size selection on request.
