Product details
Description
Engineered for heavy-duty automotive and mechanical repairs, this high-performance red RTV silicone sealant creates reliable, leak-proof instant gaskets for demanding applications. Formulated to withstand extreme thermal conditions, it handles continuous temperatures up to 600°F and intermittent spikes reaching 650°F.
The sensor-safe, low-volatile formula ensures that vehicle computer components and oxygen sensors remain protected from fouling or damage during curing. It provides exceptional resistance to common automotive fluids including transmission fluid, oil, grease, and antifreeze, while remaining flexible to resist shrinking, cracking, and peeling.
Ideal for replacing pre-cut gaskets on exhaust manifolds, timing chain covers, valve covers, and metal-to-metal joints, this professional-grade sealant delivers a secure bond with high pressure resistance. Sourced authentically from the United States, it provides the rugged dependability needed for professional mechanics and automotive enthusiasts alike.

fixed the leak finally
my old sealant kept melting near the manifold and drove me crazy. switched to this red rtv stuff last weekend and it held up against the heat without cracking. packaging was fine and delivery was quick.

good product works well
applied it on the valve cover during the weekend garage session. takes the full 24 hours to cure completely which is a bit slow if you are in a rush to drive, but once set it handles oil and grease without any issues.
