Overview
Choose BT8-1912 when you want fast installs and reliable moisture control.
Because it uses a closed-cell, non-porous structure, it helps stop sweating on cold lines and improves efficiency on warm lines.
Additionally, it stays flexible for tight routing and handles vibration common in mobile HVAC.
Function & Performance
-
Closed-cell foam blocks moisture and limits condensation.
-
Flexible construction cuts vibration and reduces line noise.
-
It performs across typical mobile HVAC line temperatures; always verify your application range.
-
Sold by the foot so you can order exact lengths; we supply a continuous length when possible.
Durability & Handling
-
The micro-cell structure keeps performance steady when you seal seams correctly.
-
You cut it cleanly with a sharp blade; then you seal joints with elastomeric adhesive or matching tape.
-
It pairs well with copper and aluminum when tubing is clean and dry.
Installation
First, measure and cut to length.
Next, dry-fit and slide the insulation over the tubing.
Then seal all longitudinal and butt joints to maintain the vapor barrier.
Finally, support the lines so you don’t compress the insulation at bends and hangers.
Applications
Use on heavy trucks, buses, off-road and ag equipment, and shop/OEM piping where elastomeric covering is specified.
