Accessories
Parts and extras to keep your filters, UV systems and pumps running well.
How to choose
- Know what you're working on: a filter housing, a UV system or a pump.
- Match brand and model where it matters. O-rings, lamps and sleeves are specific to each system.
- Check thread and tube sizes before ordering fittings and connectors.
- Changing cartridges? A housing spanner and food-grade O-ring lube make the job easier.
Common questions
How do I find the right O-ring for my housing?
Match the brand and housing size. Genuine O-rings for Davey, Pentair and Waimana Water housings are listed under Filtration Accessories.
What's the difference between push-fit and threaded fittings?
Push-fit connectors, like DMfit, join tubing without tools. Threaded fittings, like Hansen, screw together.
Do I need to replace the quartz sleeve with the lamp?
Not always. Clean it at each lamp change and replace it if it's scratched or cloudy.
Will a pump cover suit my pump?
Each cover lists the pumps it's made for. Check the product page before you order.
