Zep 143301 Gasket Maker Sealant 9 Oz Black Tube

Product Description

The ZEP 143301 is a black gasket maker sealant supplied in a 9 oz tube with a 7.25 oz net fill. It forms a flexible, durable seal on mating surfaces across a wide service temperature range, from -60 degrees F up to 450 degrees F. This product is used to create formed-in-place gaskets and to supplement or replace pre-cut gaskets on mechanical assemblies, engine components, and HVAC equipment housings. Automotive technicians, HVAC mechanics, and maintenance professionals install this sealant where a reliable, oil- and fluid-resistant seal is required on static joints and flanged surfaces.

This gasket maker is suited for residential and commercial applications wherever a formed-in-place gasket is needed. Typical uses include sealing oil pans, valve covers, timing covers, thermostat housings, and similar flanged joints in automotive and light mechanical service. Its operating temperature range also makes it appropriate for use on HVAC equipment access panels, blower housings, and ductwork flanges where low- or high-temperature exposure is a factor.

Installation Notes

Applied by licensed technicians and qualified mechanics working on mechanical assemblies. Before applying, power down or de-energize equipment and allow all components to cool completely. Clean and degrease mating surfaces thoroughly before applying a continuous bead of sealant, then assemble parts before the sealant skins over. Allow full cure time before returning the assembly to service or introducing fluids.
