Overview

PR-1422 Class B is an aircraft integral fuel tank sealant. It has a service range from -65F (-54C) to 250F (121C), with intermittent excursions up to 275F (135C). This material is designed for fillet sealing fuel tanks and other aircraft fuselage sealing applications. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas.

PR-1422 Class B is a two-part, dichromate cured poly-sulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form resilient sealant having excellent adhesion to common aircraft substrates.

Reviews

Its a fair market price for the sealant and as far as versatile sealants it s impervious to fuel, even auto fuel, oil and water. Ive used a lot over the past 15 years.

Q&A

Q: I have never used this before, do I need something more than the container it comes in to apply it to the tank surface, and if so, what? p/n 09-04703

The kit comes with a push rod for the plunger end to help push out the material. You may want to purchase a nozzle, p/n 02-00099, to help apply in tight corners, or apply narrow beads of material.
