28mm Radiator Blanking Cap

Designed for radiators that utilise a separate header tank, the Fenix radiator blanking cap seals the radiator filler neck while allowing the header tank to manage coolant expansion, pressure, and overflow.

Features:

• Suitable for 28mm radiator filler necks.
• Compatible with both deep plunger & shallow style radiator necks.
• Fenix branded sticker.

NOTE: This blanking cap must only be used with cooling systems that utilise a separate header tank. It is not suitable for radiators designed to run a standard sprung / pressure-rated radiator cap, as the cooling system may not pressurise correctly and coolant may expand out through the overflow pipe. This may result in coolant loss, overheating, cooling system issues, or engine damage.
