Type-A Radiator Cap, 1.5 BAR (21.8 PSI)

Nuke Performance Type-A Radiator Cap 1.5 BAR — High-Performance Cooling System Cap

The Type-A Radiator Cap 1.5 BAR (SKU 452-01-015) is a high-pressure option in the Nuke Performance radiator cap range, rated at 1.5 BAR (21.8 PSI). This pressure rating is suitable for performance and competition vehicles where cooling system components — including the radiator, hoses, and fittings — have been upgraded or verified to withstand elevated system pressure.

High Pressure Cooling for Motorsport Applications

Racing engines and highly modified performance engines produce significantly more heat rejection demand than standard engines. Increasing the cooling system operating pressure to 1.5 BAR raises the coolant boiling point substantially above the 1.1 BAR standard, providing critical additional margin in sustained high-load conditions encountered in circuit racing, hill climb, and time attack events across Norway, Sweden, and Denmark.

Key Features

• 1.5 BAR (21.8 PSI) pressure rating — elevated system pressure for performance applications
• Type-A format — compatible with Nuke Performance coolant expansion tanks
• Significantly increases coolant boiling margin for sustained track use
• For use with cooling system components rated for elevated pressure
• Genuine Nuke Performance motorsport cooling component

System Compatibility Requirement

Always verify that all cooling system components — hoses, clamps, radiators, heater cores, and water pump seals — are rated for 1.5 BAR before fitting this cap. The full pressure rating range (1.1, 1.3, 1.5, 2.0 BAR) is available from Arctic Performance Parts for customers in Scandinavia.
