UVC Quartz Sleeves

Maintain maximum ultraviolet penetration and protect your UV-C bulbs with our range of high-transmittance UVC quartz sleeves, replacement glass tubes, and watertight sealing O-rings. Engineered specifically for pond UV clarifiers, stainless steel sterilisers, and drum filter immersion units, premium quartz sleeves provide the vital protective barrier needed to keep electrical lamps dry while allowing peak germicidal light to pass into circulating water.

Manufactured from high-purity fused silica quartz, our replacement sleeves offer outstanding optical clarity, thermal shock resistance, and high ultraviolet-C transmission efficiency. Unlike conventional glass that blocks essential germicidal wavelengths, pure quartz ensures that full-strength UV radiation reaches suspended single-celled green algae and waterborne pathogens, keeping your pond water clear and balanced. Our collection includes both open-ended tubes and single-ended domed quartz sleeves in a comprehensive range of diameters and lengths to fit leading pond clarifiers and amalgam systems. When changing your annual UVC lamp or servicing your unit, replacing clouded, scratched, or limescale-encrusted quartz sleeves restores your clarifier to peak performance and ensures a dependable, leak-free seal.
