Permatex The Right Stuff RTV Gasket Maker — 5 oz cartridge, fast-setting oil-resistant seal

This 5 oz cartridge is engineered for rapid, reliable sealing where traditional pre-cut gaskets fall short. Designed for automotive, heavy-duty, and marine applications, The Right Stuff gives a formed-in-place rubber gasket that resists vibration, thermal cycling and common shop fluids like oil, ATF and coolant. Because it cures quickly to a tough elastomeric seal and is sensor-safe and non-corrosive, many OEMs and professional shops specify it for production and service work.

How quickly does The Right Stuff set and when can I reassemble parts?

The product is a one-minute gasket maker: it skins over fast so you can reassemble components almost immediately for many applications. Full cure and long-term elastomeric performance follow, but the rapid initial set eliminates the typical wait time for gasket adhesives.

• Initial skin-over in about one minute under normal shop conditions
• Immediate reassembly for most oil pans, covers and housings
• Final cure time varies by bead size, temperature and humidity

Which engine and drivetrain parts is it best suited for?

The Right Stuff is formulated for sealing oil-resistant, high-flexibility joints across engines, transmissions and differentials. It’s commonly used where movement and fluid exposure demand a resilient, blowout-resistant seal.

• Oil pans, timing covers and valve covers
• Transmission pans and differential covers
• Pumps, gearboxes and other housings exposed to ATF, oil or coolant

What temperatures and fluids can this gasket maker withstand?

This RTV handles a wide operating range and is engineered to resist common shop and vehicle fluids. It maintains seal integrity across severe temperature shifts and repeated thermal cycling.

• Continuous service from -75°F to 450°F (-59°C to 232°C)
• Intermittent exposure up to 500°F (260°C)
• Resistant to ATF, engine oil, coolant and many shop chemicals

Is The Right Stuff compatible with sensors and safe for metal parts?

Yes—Permatex formulated this gasket maker to be sensor-safe and non-corrosive so it won’t damage electrical sensors or attack common metal substrates. That makes it suitable for critical engine and transmission surfaces where electronic monitoring is present.

• Non-corrosive formulation safe for metal mating surfaces
• Sensor-safe chemistry for use near monitored components
• Used on OEM production lines and specified in service parts programs

Who is this for: mechanics, fleet maintenance teams, DIY enthusiasts and marine technicians who need a fast, durable alternative to pre-cut gaskets. If you work on oil pans, timing covers, transmission or differential housings and require a flexible, oil-resistant seal that sets quickly and withstands vibration and temperature extremes, Permatex The Right Stuff 29208 5 oz delivers a professional, long-lasting solution.
