Zep 143201 Gasket Maker Sealant 9 Oz Red High-temp

Product Description

The ZEP 143201 is a red, high-temperature gasket maker sealant supplied in a 9 oz tube with a 7.25 oz net fill. It forms a flexible, solvent-resistant gasket seal in place of pre-cut gaskets across a wide range of automotive and mechanical applications. Rated for service from -60 degrees F up to 550 degrees F, it handles the thermal cycling demands common in engine, transmission, and HVAC equipment applications. HVAC technicians, mechanics, and service pros use this type of silicone gasket maker when a formed-in-place seal is required on flanged joints, covers, and housings.

This gasket maker is suited for use on valve covers, oil pans, thermostat housings, timing covers, and similar gasketed surfaces in automotive and light mechanical service environments. The red color is standard for high-temperature silicone formulations and helps confirm full coverage and bead placement during application. It is appropriate for both preventive maintenance work and repair jobs where an OEM-style gasket is unavailable or where a custom bead profile is preferred.
