Product Information
Full details
The Lotus T5 Quartz Sleeve O-Ring Set is essential for pond enthusiasts who maintain UV filtration systems from Lotus, Oasis, and AquaTeck. These O-rings are specifically designed to ensure a watertight seal at the end of the quartz sleeve, protecting sensitive electrical components from water damage and maintaining optimal UV efficiency. While they are a vital maintenance component, users should note that they are size-specific and must be replaced annually to prevent the common issue of seal degradation over time.

FAQs
How often should I replace these O-rings?
It is highly recommended to replace these O-rings annually, ideally at the same time you replace your UV lamp.
Are these compatible with non-Lotus brands?
These are designed for Lotus, Oasis, and AquaTeck units. Check your specific manual to confirm it uses a standard T5 quartz sleeve size.
Do I need any special tools to install them?
No special tools are required. You should only use your hands to seat the rings to avoid scratching the quartz glass or the plastic housing.
Can I reuse the old O-rings after cleaning?
It is not recommended. O-rings lose their shape and sealing ability over time due to UV exposure and water pressure, so new rings are always safer.
Will these fit a 36w UV system?
No, this set is specific to 4w, 6w, 7w, 8w, 10w, 16w, and 18w systems.
Troubleshooting
Water visible inside the quartz sleeve
The O-ring has likely lost its elasticity or was not seated correctly. Replace with a new O-ring and ensure the groove is free of debris.
Difficulty sliding the quartz sleeve into the housing
Apply a tiny amount of silicone lubricant to the new O-rings to help them glide into the housing without catching or twisting.

Setup, Compatibility & Care
To install, first power off and unplug your UV unit completely. Carefully slide the quartz sleeve out of the housing and remove the old O-rings. Clean the groove area thoroughly with a soft cloth to ensure there is no scale or debris that could compromise the seal of the new rings. Lubricate the new O-rings with a light coating of food-grade silicone grease if recommended by your filter manual to prevent pinching. Slide the new rings into place, ensuring they sit perfectly flat within the designated slots. Regarding compatibility, this set covers 4w through 18w systems. Inspect the quartz sleeve for cracks before reinstalling to ensure the unit remains safe for operation.
