High-Performance Gasket Maker and Sealant 

Flexible Sealing for Demanding Applications

When durability, flexibility, and resistance are critical, Silicone Black RTV3 delivers superior sealing performance across a wide range of demanding applications.

Ideal for sealing engines, transmissions, pumps, and industrial equipment, it ensures long-lasting protection and precision bonding wherever it’s applied.

Built to Withstand the Heat and Pressure

Unlike standard sealants, RTV3 Black Silicone is engineered to handle high-temperature environments—making it perfect for automotive and industrial use. Once cured, it withstands continuous exposure to temperatures up to 250°C, providing a strong yet flexible seal even under intense operating conditions.

Its black colour ensures a clean, professional finish that blends well with dark metal surfaces or OEM parts, so your repairs and builds always look as good as they perform.

Versatile Performance Across Materials

This RTV silicone adheres powerfully to metal, glass, ceramics, plastics, and rubber, making it a versatile choice for professionals and DIY enthusiasts alike. Whether you’re assembling new components or replacing a worn gasket, RTV3 fills gaps and creates a dependable, leak-proof seal.

It’s also resistant to oils, water, and most automotive fluids, ensuring long-term reliability in any workshop, garage, or industrial setting.

Easy Application for Accurate Results

The 80ml tube format provides controlled, mess-free application every time. Simply clean the surfaces, apply a continuous bead of RTV3, and assemble the parts while the silicone is still tacky. Curing begins upon exposure to air and completes within 24 hours, leaving behind a flexible, durable gasket that won’t crack or shrink.
