RTV Silicone Engine Gasket Maker THREEBOND 1215 (250g)

Do Not Compromise Engine Sealing: THREEBOND 1215 Silicone Gasket Maker 250g

The reliability of an engine or a gearbox in a sports vehicle relies entirely on sealing. Choosing an inferior or unsuitable gasket maker means losing peace of mind and risking a catastrophic leak that could severely damage your high-performance mechanics.

What Will You Lose by Not Using THREEBOND 1215?

Opting for a non-professional seal or not having this silicone mastic on hand exposes your engine to costly risks:

• You risk oil loss: A failing seal between the gearbox casings or engine sumps inevitably leads to weeping. You lose the integrity of your lubrication system.
• You lose your time and money: A paste that does not resist the temperature or vibrations of sports engines will require rapid disassembly, causing you to lose valuable usage hours.
• You compromise cleanliness: Leaks from low-quality gasket makers dirty your engine and compartment, degrading the premium look of your vehicle.
• You lose ease of application: Thanks to its RTV (Room Temperature Vulcanizing) formula and extended open time, the 1215 saves you the stress of overly rapid application. You lose this comfort with instant-cure products.
