Professional RTV Black Silicone Sealant - High Temperature Engine Sealing
When engine seals fail, you need a sealant that can handle extreme heat, constant vibration, and harsh chemical exposure without breaking down. This high-grade RTV (Room Temperature Vulcanising) silicone sealant is specifically engineered for engine and housing applications where ordinary sealants simply can't cope with the punishment.
From exhaust manifold gaskets to transmission housings, this professional-grade sealant creates permanent, flexible seals that maintain their integrity through temperature extremes and mechanical stress. Perfect for automotive, marine, and industrial applications where seal failure means costly downtime and repairs.
Extreme Temperature Performance
Operating range from -60 C to +250 C with short-term resistance up to +300 C makes this sealant suitable for the most demanding engine bay applications. Whether you're sealing around exhaust components, turbocharger housings, or high-performance engine builds, it maintains flexibility and sealing integrity where other products fail.
The permanently elastic properties with 25% movement capacity mean your seals won't crack or fail as components expand and contract through heat cycles. This flexibility is crucial for modern engines that operate at higher temperatures and tighter tolerances than ever before.
Professional Grade Chemistry
The MEKO-free silicone technology provides fast, neutral curing without the corrosive byproducts that can damage sensitive engine components. Unlike acid-cure sealants that can attack metals, this neutral-cure system is safe for use on all engine materials including aluminium, steel, and cast iron.
Excellent adhesion to non-porous substrates means it bonds securely to metal surfaces without primers or special preparation. The solvent-free system eliminates shrinkage and provides consistent, reliable sealing performance that won't let you down.
Workshop-Ready Application
The 200ml cartridge with automatic dispensing makes application precise and mess-free. No mixing, no waste, no guesswork - just consistent, professional results every time. The 15-minute skin formation time gives you adequate working time while setting quickly enough to maintain productivity.
High gap-filling capacity up to 2mm handles imperfect surfaces and manufacturing tolerances without compromising seal integrity. Perfect for older engines where perfect surface preparation isn't always possible, or high-performance applications where gasket compression varies.
Durability You Can Trust
Superior UV, weather, moisture, and aging resistance ensures your seals last the life of the engine. The corrosion prevention properties protect expensive components while maintaining seal integrity through years of service. This isn't a temporary fix - it's a permanent solution.
The 12-month storage life means you can stock up with confidence, while the proven chemistry delivers consistent results whether you're doing quick repairs or complete engine rebuilds.
