## Overview

Supplied as a 6 oz low-sag paste, it ensures precise, mess-free application for professional-grade aircraft maintenance.

## Description

This material is designed for fillet sealing of 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 polysulfide compound.

It cures at room emperature to form a resilient sealant having excellent adhesion to common aircraft substrates.

Review: Not an 8-Pack - The sealant is fine, expiration date was good, but BUYER BEWARE!!! the ad says it is an 8-pack, WRONG, you get a single 6 ounce tube
