Viqua Sterilight QS-330 UV Quartz Sleeve

Description

The Viqua Sterilight QS-330 UV Quartz Sleeve is a genuine replacement sleeve designed to protect the UV lamp inside your ultraviolet water disinfection system while allowing maximum UV-C light transmission for effective water treatment. Quartz sleeves form the critical barrier between the UV lamp and the water stream—keeping the lamp dry and helping your system maintain consistent disinfection performance.

Made from high-clarity fused silica, this sleeve helps ensure full UV output reaches the water, while resisting thermal shock and buildup from minerals in the water. Over time, mineral deposits or staining can reduce UV transmission, so routine inspection and replacement are important for maintaining optimal system efficiency.

Key Features & Benefits

• Genuine Viqua/Sterilight replacement sleeve for reliable performance and fit.
• 14.8″ length (approx. 375 mm) — designed specifically for select Viqua/Sterilight models.
• Transmits germicidal UV-C light while protecting the lamp from water exposure.
• Helps maintain optimal UV disinfection performance and water quality.
• Replace if the sleeve becomes cloudy, stained, chipped, or cracked after cleaning.
• Includes O-rings (with most kits) for a secure, watertight seal.

Applications & Compatibility

This quartz sleeve is compatible with a variety of Viqua/Sterilight UV systems, including:

• S2Q-PA / S2Q / S2Q-GOLD models
• VT4 series
• SSM-17 series
• (Verify your system’s required part before ordering.)

Maintenance & Replacement

• Inspect annually when replacing the UV lamp — quartz sleeves should be cleaned to remove mineral buildup and checked for clarity.
• Replace when necessary (cloudy after cleaning, cracked, or otherwise damaged) to ensure UV light penetration isn’t compromised.
