Original UV Dynamics Replacement Quartz Sleeve for Model 400 Systems

If you need a replacement quartz sleeve for your Model 400 System, then you've come to the right place! If you don't need that, then what the heck are you doing here?

Oh, and we always recommend keeping a spare quartz sleeve on hand. The sleeves can be cleaned with CLR, but if one breaks, you want to have one on standby.
