Permatex High Tack Spray‑A‑Gasket 9 oz Aerosol — Fast‑Drying, Sensor‑Safe Gasket Adhesive & Sealant

Permatex 80065 High Tack Spray-A-Gasket in a 9 oz aerosol delivers an easy-to-apply, all-purpose gasket adhesive and sealant for automotive and light industrial assembly. It sprays on quickly, dries to a tacky paste that won’t harden or crumble, and provides resistance to fuels and common lubricants. Because it’s sensor-safe and tolerates extreme temperatures, it’s a convenient choice when you need a temporary or long-term tack to hold cut gaskets or to improve sealing during installation.

How does this sealant make installing gaskets easier?

The spray application lets you coat a mating surface or a gasket evenly and quickly, creating a sticky film that holds parts in place while you assemble them. The adhesive remains tacky indefinitely so gaskets can be positioned ahead of final assembly without losing grip. This reduces fiddling with alignment and speeds up multi-step jobs.

• Sprays on for fast, uniform coverage of flanges or gasket faces.
• Holds cut rubber, cork, paper, or composite gaskets in place.
• Lets you set parts in position before tightening bolts or clamps.

Will it resist oil, fuel, and high temperatures?

Yes — the formula is designed to withstand automotive fluids and a wide temperature span without becoming brittle or dissolving. It remains effective from -65°F to 500°F (-54°C to 260°C), and is resistant to gasoline, oil, antifreeze, axle lube, kerosene, propane and butane. These properties make it suitable for many engine- and fuel-system sealing tasks.

• Temperature stable from -65°F to 500°F (-54°C to 260°C).
• Resistant to gasoline, oil, antifreeze, and common lubricants.
• Maintains tack and sealing performance under thermal cycling.

Is Permatex High Tack safe to use around modern engine sensors?

This product is formulated to be sensor-safe, so it can be used near sensitive engine electronics and monitoring devices without degrading sensor operation. As with any aerosol, follow application instructions and avoid excessive coating of electrical connectors or exposed circuitry. Allow adequate drying time and use targeted spray techniques for best results.

• Sensor-safe formulation for use near engine sensors when applied correctly.
• Avoid direct spraying on exposed electrical terminals or connectors.
• Apply light, controlled coats and allow tack to form before assembly.

What typical applications work best with this spray gasket adhesive?

Permatex High Tack Spray-A-Gasket is commonly used for valve covers, fuel pumps, carburetors, intake and exhaust manifold gaskets, and to help seal cut gaskets on irregular surfaces. It bonds to rubber, cork, paper and composite gasket materials, providing a tacky interface that simplifies alignment and reduces leaks caused by misplacement during assembly.

• Valve covers, fuel pumps, carburetors, manifolds.
• Securing cut or pre-formed rubber, cork, paper, and composite gaskets.
• Temporary tacking during multi-part assemblies or staging repairs.

Who is this for: Permatex High Tack Spray-A-Gasket is aimed at mechanics, restoration hobbyists, fleet technicians and anyone who needs a dependable, easy-to-spray gasket adhesive and sealant. It’s especially helpful when you want a tacky, non-brittle film to position gaskets quickly, resist common automotive fluids, and tolerate wide temperature swings without compromising nearby sensors or components.
