Vorsprung TruSeal High-Performance AFLAS Coolant Gasket Upgrade

Vorsprung Autowerk TruSeal AFLAS Cooling Gasket Upgrade (Audi 3.0T)

The Ultimate High-Heat Sealing Solution for Tuned Supercharged 3.0T Engines

Engineered specifically for the Audi 3.0T (Supercharged V6), the Vorsprung Autowerks TruSeal AFLAS Gasket Upgrade replaces factory EPDM seals with a premium, motorsport-grade TFE/P fluoroelastomer compound. Designed to withstand the extreme thermal environments of modified, tracked, or heavily driven 3.0T platforms, these gaskets eliminate the premature hardening, flattening, and degradation common to factory coolant seals.

Whether you are servicing the failure-prone thermostat housing, the water pump module, or the crossover pipes beneath the supercharger, TruSeal delivers permanent resistance to chemical and thermal degradation.

Why Upgrade to AFLAS?

• True Lifetime Replacement: Impervious to extreme heat and corrosive engine fluids, our AFLAS seals will never degrade, harden, or leak, guaranteeing lifetime performance.
• Immunity to OAT Coolants & Additives: Modern Organic Acid Technology (OAT) coolants and aggressive cooling system flush additives can degrade standard rubbers over time. AFLAS features a unique chemical backbone that is completely inert to high-pH environments, amines, and coolant concentrates.
• Oil & Fuel Cross-Contamination Protection: In the valley of the Audi 3.0T, coolant seals often come into contact with weeping engine oil from the PCV system or oil filter housing. While standard EPDM swells and fails when exposed to petroleum, TruSeal AFLAS is dual-resistant, maintaining structural integrity against both oil and coolant.
• Thermal Superiority: Capable of handling continuous operating temperatures up to 200°C (392°F), these seals resist the extreme thermal cycling of pushed supercharged engines, preventing the compression set (flattening) that causes mysterious slow coolant leaks.

⚠️ Critical Climate Disclaimer (Warm Climate Only)

IMPORTANT APPLICATION NOTE: AFLAS is a specialized compound optimized for high-temperature and extreme chemical environments. It possesses a higher glass transition temperature than factory EPDM rubber.

• Temperature Limitation: These gaskets are strictly rated for ambient operational temperatures above -5°C (23°F).
• Geographic Constraint: Do not install this product on vehicles operated in geographical regions that experience sub-freezing winter climates or overnight freezing soaks. In temperatures below 23°F, the material will temporarily lose its elasticity and harden, which can cause coolant weeping upon cold startup until the engine reaches operating temperature. For cold-weather regions, standard peroxide-cured EPDM or low-temperature FKM gaskets must be used.

TruSeal AFLAS Coolant Gasket FAQ

Can I install this if I live somewhere with cold winters?
No. AFLAS is rated only for ambient temperatures above -5°C (23°F). In colder climates, use a standard peroxide-cured EPDM or low-temperature FKM gasket instead.

What components use this gasket?
It's used when servicing the thermostat housing, water pump module, or crossover pipes beneath the supercharger on the 3.0T platform.

Why not just use the factory EPDM seal?
Factory EPDM hardens and flattens under the extreme heat cycling of a tuned or tracked 3.0T, and can swell when exposed to oil weeping from the PCV system. AFLAS resists both.

Does this work with modern OAT coolants?
Yes. AFLAS is chemically inert to Organic Acid Technology coolants and cooling system flush additives that degrade standard rubber over time.

Is this a lifetime part?
Within its rated warm-climate application, yes — it's designed to resist the degradation and compression set that causes factory seals to eventually leak.
