QT-090028 Replacement Quartz Sleeve for Xylem Wedeco LCS4 & LCE4 UV Systems

Replace a damaged, cracked or fouled quartz sleeve in your compatible Xylem Wedeco UV disinfection system with a replacement QT-090028 quartz sleeve.

The QT-090028 is a pure fused quartz sleeve with a 28mm outside diameter, designed for compatible UV systems including the Xylem Wedeco LCE4 / UViFLO 4,000-D range.

The quartz sleeve is supplied with a replacement O-UV-G28-S O-ring, helping provide a reliable seal around the quartz sleeve during installation.

Compatible Xylem Wedeco UV Systems

The QT-090028 replacement quartz sleeve is associated with compatible Xylem Wedeco LCE4 UV systems and the UViFLO 4,000-D range.

A compatible quartz sleeve is an important component of the UV reactor because it separates the UV lamp from the water while allowing UV-C energy to pass through the quartz and into the water.

If you are replacing the quartz sleeve on an LCS4 or LCE4 system, we recommend confirming the part number and dimensions of your existing sleeve before ordering.

Check Your Existing Quartz Sleeve Before Ordering

UV quartz sleeves are available in many different lengths, diameters and end configurations.

Before purchasing a replacement, we recommend checking:

• Existing quartz sleeve part number
• Outside diameter
• Overall length
• End configuration
• UV system manufacturer and model

If you are unsure whether QT-090028 is the correct replacement for your system, send us a clear photograph of the UV system identification label and existing quartz sleeve. Our team can assist with identifying the appropriate replacement.

Why Does a UV System Need a Quartz Sleeve?

A UV lamp needs to be isolated from the water while still allowing the UV-C light generated by the lamp to pass into the water.

The quartz sleeve provides this separation.

It protects the UV lamp from direct contact with the water while allowing UV-C energy to transmit through the quartz and into the water being treated.

For this reason, the condition of the quartz sleeve can have an important effect on the performance of a UV disinfection system.

Fouling and Scale Can Reduce UV Transmission

Over time, minerals, scale, iron, manganese and other deposits can build up on the outside of a quartz sleeve.

This contamination can reduce the amount of UV-C energy transmitted from the lamp into the water.

A UV lamp may still be operating and producing visible light, while deposits or fouling on the quartz sleeve reduce UV transmission.

Regular inspection and cleaning of the quartz sleeve should therefore form part of a routine UV system maintenance program.

If the sleeve is damaged, heavily stained, scratched or cannot be adequately cleaned, replacement should be considered.

Replace the O-Ring When Replacing the Quartz Sleeve

The QT-090028 replacement quartz sleeve is supplied with an O-UV-G28-S O-ring.

Replacing the O-ring at the same time as the quartz sleeve is recommended rather than reusing an old seal.

A new O-ring can help provide the correct seal between the quartz sleeve and the UV reactor assembly and reduce the risk of leaks following reassembly.

QT-090028 Quartz Sleeve for LCE4 UV Systems

The QT-090028 is associated with the Xylem Wedeco LCE4 / UViFLO 4,000-D UV disinfection system.

Published spare-parts information identifies the 4000-D-28 system with:

• L-GXO860 UV lamp
• QT-090028 quartz thimble
• O-UV-G28-S O-ring

This makes the QT-090028 an important replacement component when servicing compatible UV systems.

Consider Replacing the UV Lamp at the Same Time

If the quartz sleeve is being replaced as part of an annual service, it can be a good opportunity to inspect or replace the UV lamp at the same time.

Water Filtration Solutions supplies the compatible L-GXO860 replacement UV lamp for applicable Xylem Wedeco LCS4 and LCE4 systems.

Replacing the lamp and quartz sleeve together can simplify scheduled maintenance and reduce the need to dismantle the UV system multiple times.

Complete LCS4 & LCE4 Annual Service Kit

If you are carrying out a complete annual service rather than replacing the quartz sleeve only, our Xylem Wedeco LCS4/LCE4 annual service kit may be a more convenient option.

The service kit includes the key components required for routine maintenance, including:

• L-GXO860 replacement UV lamp
• QT-090028 replacement quartz sleeve
• O-UV-G28-S replacement O-ring

This can provide a convenient option for customers looking to complete routine UV maintenance using a single service kit.

If you are unsure which quartz sleeve you require, contact our team before ordering. Providing the UV system model, existing part number or a photograph of the current quartz sleeve can help us confirm compatibility.

Frequently Asked Questions

What is a QT-090028 quartz sleeve?

QT-090028 is a replacement UV quartz sleeve/thimble used with compatible Xylem Wedeco UV disinfection systems. It is made from pure fused quartz and has a 28mm outside diameter.

What UV system uses QT-090028?

QT-090028 is associated with the Xylem Wedeco LCE4 / UViFLO 4,000-D UV system range. Always confirm your existing system and part number before ordering.

What size is the QT-090028 quartz sleeve?

The QT-090028 has a 28mm outside diameter. It is a domed-end fused quartz sleeve.

Does the QT-090028 include an O-ring?

Yes. The WFS replacement QT-090028 quartz sleeve is supplied with an O-UV-G28-S replacement O-ring.

When should a UV quartz sleeve be replaced?

A quartz sleeve should be inspected during routine UV maintenance. Replacement may be required if the sleeve is cracked, damaged, scratched, heavily fouled or cannot be adequately cleaned.

Can I clean the quartz sleeve instead of replacing it?

In some cases, a quartz sleeve can be carefully cleaned to remove mineral deposits and other fouling. If the quartz is damaged, scratched, cracked or remains heavily contaminated after cleaning, replacement is recommended.

Should I replace the O-ring when replacing the quartz sleeve?

Yes. It is good maintenance practice to install a new O-ring when replacing the quartz sleeve rather than reusing an old seal.

Do I need to replace the UV lamp when replacing the quartz sleeve?

Not necessarily. However, if the UV lamp is approaching the end of its recommended operating life, replacing it at the same time can be a convenient way to complete the system’s scheduled maintenance.

How do I know if QT-090028 is the correct quartz sleeve for my UV system?

Check the model and part number of your existing UV system and quartz sleeve. If you are unsure, send Water Filtration Solutions a photograph of the system identification label and existing quartz sleeve and we can help confirm the correct replacement.
