Viqua SHO320-QL UV Lamp & Quartz Sleeve

Description

The Viqua SHO320-QL UV Lamp & Quartz Sleeve Kit is a genuine replacement combo designed to restore the performance of your Viqua/Sterilight UV disinfection system. This all-in-one kit includes a high-output UV lamp and matching quartz sleeve — the two most important components for effective ultraviolet water purification. By replacing both parts together, you ensure your system continues to deliver safe, bacteria-free water with optimal UV light transmission.

Key Features

• Complete lamp and sleeve replacement kit including: UV lamp (S320RL-HO) and quartz sleeve (QS-320).
• Designed for easy annual maintenance — replace the lamp every year and the sleeve when cleaning no longer restores clarity.
• Genuine Viqua/Sterilight parts for reliable fit and performance.
• Helps maintain proper UV-C output for microbial inactivation.
• Includes necessary O-rings in many kits for a complete service.

Compatibility

Compatible UV Systems

This replacement kit fits the following Viqua/Sterilight residential and light-commercial UV systems:

• SPV-6
• SP320-HO
• SC-320
• SCM-320

These systems use a high-output 37 W UV lamp and require the QS-320 quartz sleeve for proper UV disinfection performance.

⚠️ Always verify your specific system model before ordering replacement parts to ensure proper fit and performance.

Compatible UV Lamps

• S320RL-HO UV Lamp — the high-output lamp included in this kit, designed to deliver strong UV-C intensity (≈ 37 W) and typically replaced annually to maintain system efficiency.

If you need individual components instead of the kit, you can purchase a separate replacement lamp or sleeve, but bundled kits like this make maintenance simpler and usually more cost-effective.

Specifications

• Part Number: SHO320-QL
• UV Lamp Model: S320RL-HO high-output lamp
• Quartz Sleeve Model: QS-320
• Lamp Length (approx.): 16.5″ (42 cm)
• Sleeve Length (approx.): 17.8″ (45.2 cm)

Applications

Ideal for residential and cottage water systems where ultraviolet light disinfects well or municipal water. This kit restores your UV system’s ability to inactivate bacteria, viruses, and other pathogens without chemicals — a clean, sustainable way to treat drinking water.

Maintenance

• Annual lamp replacement is recommended even if the lamp still glows — UV intensity decreases over time.
• Quartz sleeve should be inspected and cleaned each time you service the system; replace if it remains cloudy, stained, or cracked after cleaning.
• Replacing both lamp and sleeve together helps ensure your system operates at peak performance.
