IceCap 90 Watt UV Replacement Quartz Sleeve (SKU: IP-UV-90SLV)
The IceCap 90 Watt UV Replacement Quartz Sleeve (SKU: IP-UV-90SLV) is an authentic, structural OEM replacement component distributed by CoralVue to preserve peak ultraviolet output and maintain a safe electrical barrier in massive marine filtration systems, large multi-tank aquaculture arrays, and commercial ponds. Inline ultraviolet sterilization acts as an absolute biosecurity line, scrambling the cellular DNA/RNA profiles of problematic dinoflagellates, cloudy bacterial blooms, and aggressive waterborne fish parasites. However, the system relies entirely on the clarity of the elongated quartz sleeve shielding the hot germicidal bulb. Because this sleeve is continuously subjected to an immense, pressurized stream of mineral-heavy water, it naturally accumulates a dense layer of calcium scaling and organic slime over months of use. This accumulation permanently clouds the glass, acting like a physical shield that prevents vital UVC rays from interacting with passing water.
Molded to meet tight commercial manufacturing tolerances, this specialized replacement quartz tube drops directly into the internal housing tracking of the flagship IceCap 90W External Inline UV Sterilizer (IC-HOUV-90W). Unlike cheap consumer-grade glass tubes that filter out high-energy wavelengths, the IP-UV-90SLV features a specialized optical-grade quartz structure that provides near-flawless light transmission. Swapping out an old, heavily crusted or accidentally scratched sleeve during your annual maintenance refresh ensures your high-volume display remains crystal clear while keeping raw saltwater completely isolated from your dry electronic ballast wiring loops.
Key Features
Guarantees Uncompromised Pathogen Kill Rates: Maximizes germicidal 254nm radiation delivery across the contact chamber, turning back rapid parasite or green hair algae outbreaks.
Bypasses Overtightening Stress Fractures: Serves as an immediate direct replacement for hobbyists who accidentally cracked or shattered their original sleeve during a routine descaling teardown.
Eliminates Ballast and Pump Short-Circuits: Re-establishes a flawless structural barrier inside the heavy-wall vessel casing to keep pressurized saltwater out of live high-voltage terminal lines.
(Note: This retail SKU contains (1) individual standalone 90W UV Quartz Sleeve. Threaded housing compression nuts, replacement blue rubber O-ring seal packs, high-output replacement bulbs, and external mounting clips are sold under separate product categories).

- Shut down your primary return pump or the dedicated feed line supplying your inline 90W UV loop. Close any ball valves upstream and downstream to isolate the UV circuit, and completely drain the internal water column.
- Unthread the protective cord-lock assembly nut on top of the housing lid and slide the massive high-output 90W UV bulb assembly entirely out of the dry sleeve core. Set the bulb down carefully on a soft towel.
- Unthread the master compression quartz sleeve housing nut holding the top flange of the glass tube down against the internal vessel framework.
- Carefully pull the long quartz sleeve straight up and away from the body. Warning: Because this is a massive 35+ inch glass tube, support the body evenly with both hands. If the sleeve is shattered or cracked, use protective gloves to remove the broken glass fragments and clean the inner seat track completely.
- Remove the old blue rubber sealing gaskets from the track, wipe the groove clean of any debris, and seat a fresh, level rubber gasket pack into position.
- Slide your new IP-UV-90SLV quartz sleeve straight down into the center cavity until it catches the bottom tracking groove, thread the housing compression nut clockwise entirely by hand until tight, lower your bulb back inside, re-secure the top locking ring, and check for leaks before restoring power.
Pro Tips:
- Never Use Pliers or Metal Hand Tools to Tighten the Housing Compression Nut. When securing your fresh IP-UV-90SLV quartz sleeve back into the top of the commercial sterilizer column, always thread and tighten the plastic housing compression nut entirely by hand. Never use household pliers, channel locks, or pipe wrenches. The high brute-force torque from a metal tool will instantly over-compress the top lip of the glass tube, causing the fragile quartz flange to fracture, shatter, or develop a hidden hairline crack that will cause an active water leak once it is placed under pressure.
- Always Dry-Test Your Blue Gasket Configuration Before Turning on the Ballast. The waterproof sealing system on the 90W inline housing depends entirely on the blue ring gaskets compressed by the main housing nut. When lowering the new long quartz sleeve into place, check that the blue gaskets sit perfectly flat, even, and level within their recessed tracking grooves. If a gasket twists or rolls even a tiny fraction during reassembly, it will create a microscopic gap. Water will slowly track through that gap and flood the inside of the sleeve, shorting your electronics, ruining your bulb filaments, and tripping your home GFCI breaker.
- Soak Your New Sleeve in Vinegar or Citric Acid Every 3 Months to Avoid Replacement. To ensure you get multiple years of reliable service out of your fresh quartz sleeve without having to replace it prematurely, make it a strict habit to pull the tube out and descale it every 3 months. Because the heat generated by the internal bulb causes calcium carbonate to continuously bake onto the outer glass face, a thick white crust forms quickly. Never attempt to scrape this crust off with steel wool, razor blades, or wire brushes, as you will permanently scratch the quartz. Instead, soak the entire tube in a warm citric acid or white vinegar bath for 20 minutes to dissolve the scale completely.
