Permatex The Right Stuff Black Silicone Gasket Maker, 1-Minute Cure, 3 oz
Permatex The Right Stuff Black Silicone Gasket Maker, 1-Minute Cure, 3 oz
Permatex The Right Stuff Black Silicone Gasket Maker is a fast-curing RTV silicone sealant that forms a leak-proof elastomeric seal around virtually any surface, replacing the need for a traditional cut gasket. It is designed for oil pans, timing covers, transmission pans, and similar sealing applications where a durable, form-in-place gasket is needed. The formula returns the equipment to service in just 1 minute, making it well suited for repairs where downtime matters.
This sealant is highly flexible once cured, allowing it to absorb vibration and movement without cracking. It is a sensor-safe RTV silicone formula, so it will not interfere with oxygen sensors or other engine sensors. The Right Stuff is also oil resistant and holds up to weathering and thermal cycling, forming a fully bonded seal that resists hardening, shrinking, and cracking over time compared to conventional gaskets.
