Tridon Radiator Cap – TRC11 | Blanking | Metal Bayonet Style

Protect your cooling system with quality you can trust.

The Tridon TRC11 is a blanking radiator cap designed for systems that do not require a pressure-rated cap. Commonly used on overflow bottles or header tanks, this cap seals the system to prevent coolant loss while ensuring long-lasting reliability.

Product Features:

• Series: TRC
• System Type: Blanking (non-pressure)
• Cap Style: Metal
• Connection Type: Small bayonet
• Use Case: Ideal for overflow bottles or sealed systems using a separate pressure cap
• Built for durability and corrosion resistance

Why it matters:

The radiator cap plays a critical role in engine protection and coolant retention. If it’s worn or not sealing properly, it can lead to overheating or coolant leaks. The TRC11 offers a reliable blanking solution for systems that need a tight seal without pressure regulation.

For help choosing the right cap for your vehicle, consult your vehicle’s manual or contact your parts specialist.
