Permatex 81624 Ultra Red High-Temp Gasket Maker – 13 oz | Oil-Resistant, OEM-Specified

Overview

Permatex’s Ultra Red Gasket Maker is a versatile, high-temp sealant designed for demanding automotive and mechanical applications. Its advanced formulation aims to resist oils and common shop fluids while maintaining adhesion, flexibility, and a practical ease of use. The result is a dependable surface for gaskets and dressings that can endure heat and vibration without becoming brittle or losing seal integrity.

Why choose Permatex Ultra Red Gasket Maker

• High temperature performance, adhesion and flexibility
• OEM Specified, Sensor-safe, low odor, non-corrosive
• Non-flammable, non-toxic
• Can be used as a gasket maker or dressing and meets performance specs of OE silicone gaskets
• Withstands up to 650°F (399°C) intermittent

In practice, the sealant spreads smoothly to form a pliable gasket surface that remains effective under heat, oil exposure, and engine motion. Its texture feels silky as you apply a thin bead along flange edges, and the red hue helps you see coverage clearly without smearing onto unintended areas.

Real-world uses

• Engine gasket applications: timing covers, valve covers, and oil pans where heat and fluids are common
• Intake and exhaust gasket surfaces that experience temperature swings and oil contact
• Thermostat housings, water pumps, and other components requiring a dependable seal
• Gasket dressing on OE silicone gaskets to enhance sealing performance while preserving gasket specs

Users may notice a mild odor and sensor-safe profile, which can help crews work around sensitive components without harsh fumes. The product is non-flammable and non-toxic, aligning with common shop safety practices and allowing for flexible, on-site use.

How to use and care

• Prepare clean, dry surfaces; remove old gasket material and oil residue
• Apply a consistent bead along the gasket edge or onto the mating flange
• Assemble parts within recommended timeframes and allow the surface to set per OEM guidance
• Inspect for uniform compression and check for leaks after initial startup

For best results, follow the OEM’s surface preparation recommendations and use within the product’s temperature tolerance to achieve the intended sealing performance. This gasket maker offers a practical balance of heat resistance, fluid compatibility, and ease of use for common automotive sealing tasks.
