UV Dynamics 400435 UV Quartz Sleeve

Description

The UV Dynamics 400435 UV Quartz Sleeve is a genuine replacement quartz sleeve engineered for use in select UV Dynamics ultraviolet water disinfection systems. It is specifically designed to protect the UV lamp while allowing maximum transmission of germicidal UV-C light into the water stream — critical for delivering effective microbial inactivation.

Key Features

• OEM Replacement Sleeve – Made to original specifications for proper fit and performance in compatible UV Dynamics systems.
• High-Purity Quartz Construction – Excellent ultraviolet light transmission ensures that the UV lamp’s germicidal output is delivered effectively through the water.
• Protects the UV Lamp – Prevents direct water contact with the lamp while allowing UV-C light to penetrate the water stream.
• Includes Replacement O-Rings – Seals securely in the UV chamber to prevent leaks when installed.
• Easy to Service – Designed to be swapped out quickly with your regular UV lamp change — usually once per year.

Compatibility

This quartz sleeve is the correct match for systems that use the UV Dynamics 400434 UV Lamp, including:

✔ UV Dynamics UVD180 ultraviolet disinfection systems

✔ UV Dynamics UVD245 ultraviolet disinfection systems

These models are commonly used for residential and light-commercial whole-house UV water disinfection applications with rated flows where UV Dynamics lamps and sleeves of this size are specified.

📌 Note: Always check your system model label or manual to confirm compatibility before purchasing — different UV models use different lamp/sleeve sizes.

Specifications

• Part Number: 400435
• Type: Quartz UV sleeve / lamp protective tube
• Material: High-purity UV-grade quartz
• Function: Protects the UV lamp and maximizes UV transmission
• Includes: Quartz sleeve + replacement O-rings (unless specified otherwise)
• Use: Cold water disinfection systems

Why This Part Matters

In a UV disinfection system, the lamp generates the germicidal UV-C light and the quartz sleeve allows that light to pass into the water without obstruction. Over time, mineral scale, sediment, or discoloration can build up on the sleeve, reducing UV light transmission and lowering disinfection effectiveness. Replacing the quartz sleeve during routine service — often when the lamp is replaced — helps maintain validated performance and ensures your system continues to protect against bacteria, viruses, and other pathogens.

Maintenance & Replacement

• Lamp & Sleeve Together: When servicing your UV unit, it’s best practice to replace the quartz sleeve at the same time as the UV lamp (e.g., 400434), ensuring the strongest possible UV dose.
• Cleaning: Inspect the sleeve for scale or deposits at each lamp change. If it appears cloudy or stained, replace it rather than just clean it.
• O-Ring Care: Always install new O-rings or lubricate existing ones with food-grade silicone grease to prevent leaks.

Applications

This quartz sleeve is suitable for:

• Residential UV water disinfection
• Well water and municipal pre-UV systems
• Whole-house UV installations
• Light commercial UV disinfection systems

By replacing the sleeve at proper intervals, you help maintain optimal UV performance and long-term system reliability.
