Pentair SMART UV Sterilizer Quartz Sleeve

Go by the wattage on the vessel label — the table above lists the model each part number fits, and several sleeves are shared between two wattages.

Ordinary glass absorbs UV-C at 254 nm; high-purity quartz passes it, so a quartz sleeve protects the lamp without cutting the dose reaching the water.

Inspect after the first three months and set your interval from what you find — hard water, iron and biofilm all foul faster, and any film on the sleeve reduces the dose.

When it is cracked, chipped, deeply scratched, etched or the fouling will not come off — all of those permanently reduce UV transmission through the sleeve wall.

Yes — renew the sleeve gasket and O-rings any time the sleeve or lamp comes out; the 960533-P gasket suits every SMART UV model and O-ring service kits are stocked by size.

No — the sleeve keeps the lamp dry and at its correct operating temperature, and running a lamp in direct water contact will cool it, cut its output and destroy it.

Prices are shown in the dropdown above; select the part number for your wattage, or contact us if your model is not listed.
