10 PSI 0.7 BAR Billet Aluminum Radiator Cap Raw | Fits Small 32mm Neck

Designed for high-performance cooling systems, this CNC Billet Aluminum Radiator Cap is the same high-quality component we use in our radiators, expansion tanks, and swirl pot setups.

Crafted from 6061 billet aluminum, this cap is lightweight, strong, and corrosion-resistant. It is available in raw aluminum or black anodized finish, providing both function and style. This cap will ensure that your cooling system maintains the necessary pressure for maximum efficiency. Key Features: Premium 6061 Billet Aluminum – Strong, lightweight, and built for durability.
