Constructed from high-quality quartz material, the sleeve is durable, heat-resistant, and resistant to UV radiation, ensuring long-term performance and reliability.

The quartz sleeve is transparent, allowing UV light emitted by the lamp to pass through effectively without significant attenuation or loss of intensity, maximizing the sterilization efficiency.

The sleeve acts as a protective barrier around the UV lamp, preventing direct contact between the lamp and water while allowing UV light to pass through.
