Gear Oil Rtv Sealant 3oz 12pk - Permatex

The Permatex 81182 Gear Oil RTV Sealant is an oxime-cure gasket maker specifically engineered for the demanding conditions found in differentials, transfer cases, and other critical driveline components. This professional-grade formulation provides reliable, leak-proof sealing, resisting breakdown from aggressive conventional and synthetic gear oils, including the performance-enhancing friction modifiers often present in modern axle designs. Each 12-pack case of 3 oz tubes ensures technicians have a consistent supply of this sensor-safe silicone, delivering flexible and durable gaskets for long-term integrity in both automotive and industrial applications.

Key Features

• Gear Oil Specific Formulation: Designed to withstand continuous exposure to aggressive gear lubricants and friction modifiers, offering enhanced durability where standard RTV sealants may fail.
• Formed-in-Place Gasket: Effectively fills surface imperfections, replacing or complementing traditional pre-cut gaskets to minimize leaks and reduce the need for reworks.
• Wide Temperature Resilience: Maintains a robust and flexible seal across a broad temperature range from -65°F to 500°F (-54°C to 232°C), suitable for high-load, high-temperature environments.
• Sensor-Safe and Non-Corrosive: Engineered to prevent corrosion on aluminum, steel, or cast iron housings and is safe for use around ABS, speed, and other sensitive driveline sensors.
• Efficient Curing Profile: Skins in approximately two hours and achieves full cure within 24 hours under standard shop conditions, facilitating efficient workflow for professional service.

Applications

This Permatex RTV sealant is ideal for creating durable, leak-proof seals in critical driveline assemblies, including:

• Resealing front and rear differential covers on passenger cars, light trucks, SUVs, and heavy-duty axles.
• Sealing transfer case halves and covers on 4WD and AWD vehicles.
• Gasketing axle housings and inspection covers exposed to high-load gear lubricants.
• Can be utilized as a primary gasket maker or as a supplementary dressing to enhance the seal of original equipment gaskets.

(Note: Not recommended for cylinder head gaskets or components exposed directly to gasoline.)
