Permatex Fillers, Adhesives & Sealants

Permatex products in this category

Permatex products in the Fillers, Adhesives & Sealants category cover several common automotive repair and maintenance tasks. The selection includes gasket makers, silicone adhesive sealants, threadlockers, thread sealants, exhaust sealers, and spray adhesive for interior parts.

Use the product titles and specifications to narrow your search by the job you need to complete. Some formulas are designed for high-temperature applications, while others emphasize oil resistance, flexibility, rigid sealing, or high-strength adhesion.

Gasket makers and silicone sealants

The catalog includes RTV silicone gasket makers in black, red, and gray formulas. Their listed features distinguish them by intended performance, including oil resistance, high-temperature use, high flexibility, sensor-safe and non-corrosive characteristics, or suitability for rigid high-torque applications.

Black silicone adhesive sealant is another option shown in the listings. These products may be relevant when you need an adhesive and sealing compound rather than a gasket maker alone. Review each listing for the stated application, cure-related information, form factor, and dispensing format.

Threadlockers, thread sealants, and repair adhesives

Permatex thread products include a medium-strength blue threadlocker and a high-temperature white thread sealant. Threadlocker is generally selected to help secure threaded fasteners, while thread sealant is intended for sealing threaded connections. Match the product type to the connection and the conditions described in its specifications.

The selection also includes muffler and tailpipe sealer for exhaust-related work, plus a heavy-duty headliner adhesive in an aerosol format. The headliner product is described for repairing detached or loose interior parts and drying clear, making the listed finish and spray format useful comparison points.

How to choose between Permatex models

Start with the repair location and the material or connection involved. Then compare the product details for:

• Application: gasket, thread, exhaust, interior trim, or general adhesive sealing.
• Performance needs: oil resistance, temperature resistance, flexibility, rigidity, or strength.
• Format: tube, sealant, or aerosol spray, depending on access and the size of the repair.
• Compatibility details: sensor-safe, non-corrosive, color, and any specific use guidance in the listing.
