Product Information
Full details
The Laguna Pressure-Flo Quartz Sleeve is an essential replacement component for pond owners utilizing Laguna Pressure-Flo 4000/7500 or PowerClear Multi 3500/7000 filtration systems. This genuine spare part is designed to house the UV bulb, protecting it from direct water contact while ensuring maximum UV light penetration for effective pond clarification. While it is a critical component for maintaining water health, it is made of fragile quartz glass and requires careful handling during installation to prevent cracks or breakage.

FAQs
Do I need to replace the O-ring when replacing the quartz sleeve?
It is highly recommended to inspect the O-ring for any signs of wear or cracking. If it is not perfectly pliable, replace it to ensure a watertight seal.
Can I touch the quartz glass with my bare hands?
It is best to handle the sleeve with clean gloves or a soft cloth. Skin oils can cause uneven heating on the glass surface.
How often should I clean the quartz sleeve?
Cleaning should be performed whenever you replace your UV bulb or if you notice visible limescale buildup, typically every 6 months depending on water quality.
Is this compatible with generic UV clarifiers?
No, this is a proprietary part designed specifically for Laguna Pressure-Flo and PowerClear systems. It may not fit other brands.
What happens if the sleeve cracks?
If the sleeve cracks, water will enter the UV bulb chamber, which will cause the bulb to fail immediately and could damage the internal electrical components of your filter.
Troubleshooting
Water inside the quartz sleeve
The sleeve is likely cracked or the O-ring seal is improperly seated. Inspect the sleeve for hairline fractures and replace the O-ring if it appears flattened or brittle.
UV light appears dim or ineffective
Mineral deposits have likely built up on the glass. Remove the sleeve and clean it with a vinegar-based solution to ensure maximum UV light transmission.
Pros and Cons

Cons
- Made of delicate quartz glass susceptible to cracking

Setup, Compatibility & Care
To install, ensure the filtration unit is disconnected from the power supply and the water flow is turned off. Carefully remove the UV assembly from the filter lid. Gently unscrew or release the old quartz sleeve, keeping track of the O-rings or seals. Slide the new sleeve into place, ensuring the seal is lubricated and seated perfectly to maintain a watertight environment.

Care Instructions: Handle the quartz sleeve only by the edges where possible. Oils from your skin can create hot spots on the glass when the UV lamp is running, which can shorten the lifespan of both the sleeve and the bulb. Clean the exterior surface monthly using a soft cloth and a mild descaling agent if your water is "hard."
