Vital Black RTV VT-157SE replaces traditional gaskets on engine components and industrial machinery. It cures at room temperature into a flexible silicone rubber capable of withstanding 315°C. This acetoxy-system sealant resists automotive oils and common fluids. The updated 70g tube replaces the previous 85g version for more efficient single-job application.
Key Features
- Thermal Stability: Operates between -62°C and 315°C. Seals components through extreme thermal cycling.
- Fluid Resistance: Chemically stable against motor oil and transmission fluids. Stops leaks in high-lubricant environments.
- Fast Tacking: Reaches a tack-free state in under 25 minutes. Speeds up assembly in heavy humidity.
- High Elasticity: Elongation exceeds 300% with 1.2 MPa tensile strength. Maintains a seal during heavy vibration.
- Material Integrity: Hardness rating of 18 Shore A prevents shrinking. The gasket stays firm without cracking.
Frequently Asked Questions
How long does Vital Black RTV take to dry?
