The Stanley Mini Radiator Refills are medium pile roller sleeves designed for professional painting applications with emulsion and water-based paints. These compact 4-inch refills are ideal for radiators, narrow surfaces and detailed work where standard-size rollers cannot reach. Manufactured from woven polyacrylic with a 12mm pile height, these sleeves deliver excellent coverage and a quality finish on both smooth and semi-rough surfaces. The medium pile construction ensures optimal paint pickup and release, whilst the durable material provides extended service life across multiple projects. The mini radiator format makes these refills particularly suitable for painting behind radiators, in confined spaces, and for cutting in around architectural features. The 6mm wire core diameter ensures secure fitting to compatible mini roller frames, maintaining stability during application.
