Motorcycle Radiator Pressure Cap – 0.5 to 2.0 Bar

Product Description

Premium motorcycle radiator pressure caps, engineered for reliable performance across a wide range of cooling system requirements. These caps are made and assembled in England (UK) and offered in multiple pressure ratings, suitable for standard road bikes, performance motorcycles, and specialist applications.

High-pressure variants feature a stainless steel case for excellent corrosion resistance and durability, while the low-pressure 0.5 bar option is supplied with a zinc-coated steel case, ideal for older or sensitive cooling systems.
