Overview

PR-1428 Class B is a low adhesive sealant. It has a service temperature range -65F (-54C) to 250F (121C), with intermittent excursions up to 250F (135C). The material is designed for use as an access door sealant or in the fabrication for form-in-place (FIP) gaskets. It can also be used to protect electrical wired, terminals and equipment against fuel moisture, dirt and short circuits.

After a long search for Cessna 172RG fuel tank plate sealant part number. I ordered it from Air Spruce. And the sealant has the right amount for plates. 6 oz. I dont order much like bulk. But Air Spruce is a good company to order from. Gennaro Bruno
