Description
xOverview
Permatex 81160 High-Temp Red RTV Silicone Gasket Maker is a durable formed-in-place sealant designed for demanding automotive and heavy-duty applications. Instead of relying solely on cut gaskets, it creates reliable seals directly in place, adapting to mating surfaces and contours for a snug fit that holds up under thermal cycling. The vivid red silicone formula also helps coat pre-cut gaskets to boost their reliability during operation.
Why this matters
- Engineered for hi-temp environments or heavy-duty service where seals must endure daily use and tougher conditions.
- Forms in-place gaskets that resist cracking, shrinking, and migration as temperatures fluctuate.
- Coats pre-cut gaskets to improve leak resistance and seal integrity.
- Wide temperature tolerance supports intermittent exposure from -65°F to 650°F, broadening its applicability.
Key capabilities
In addition to sealing, the product demonstrates strong oil resistance and torque-retention characteristics, which are valuable in engines and assemblies exposed to fluids and vibration. The formula is noted as sensor-safe and compatible with modern materials such as aluminum, bi-metal alloys, and high-tech plastics, aligning with both OEM production needs and service tasks.
Real-world use cases
- Engine bays and heavy-duty applications where towing, performance, or daily driving demand dependable seals.
- Applications involving new component materials that can benefit from a flexible, formed-in-place gasket.
- Maintenance tasks that prefer sealing in place rather than sourcing and installing multiple pre-cut gaskets, saving time and reducing complexity.
Usage notes
The gasket maker is designed to resist thermal cycling and maintain a reliable seal across a range of fuels and lubricants. While results depend on the specific joint and materials, the formulation offers a practical option for OEM-grade sealing and service tasks that require a formed-in-place solution.
Specifications at a glance
OEM heritage, robust oil resistance, tarry-free performance, and compatibility with modern engine components help it fit into both production and field service workflows. For jobs involving aluminum, bi-metal alloys, or advanced plastics, this product presents a familiar, sensor-safe sealing choice.
