PPG® PR-2001 B-2 Fuel Tank Sealant – 6 oz 654-SemKit is a rapid-curing, gray elastomeric compound designed for fillet and general fuel tank sealing applications inside aviation fuel tanks.

This Type 2, Grade 1 sealant features a low-sag formula for easy application on vertical or horizontal surfaces using an extrusion gun or spatula. Packaged as a two-component kit to keep ingredients separate until use, it ensures reliable, aerodynamic smoothing protection to stop leaks before they start.
