Klir 7in Filter Sock Di-7 Adapter Set
SKU: CV-KLIR-FSRING7
- Universal Sump Conversion Solution: Eliminates fitting issues across various custom aquarium sump brands by altering the frame's mounting diameter.
- Dual Multi-Spec Sizing Profiles: Arrives packed with (1) 6.9-inch diameter adapter collar and (1) 7.25-inch expanded diameter adapter ring.
- Stops Unfiltered Water Bypass: Forms a tight, flush support platform over your sump's sock panel, forcing all incoming drain water directly through the wide 50-micron fleece.
- Heavy-Duty Snap-Fit Construction: Precision-molded from rigid, cell-cast saltwater-inert polymers that resist micro-cracking, stress warping, and salt creep.
- Tool-Free Interchangeable Setup: Swaps out easily by hand, sliding over the main chassis tracks without requiring messy aquarium silicone or plumbing modifications.

Klir Di-7 7-Inch Filter Sock Adapter Collar Set
The Klir Di-7 7-Inch Filter Sock Adapter Collar Set (SKU: CV-KLIR-FSRING7) is an authentic structural OEM replacement hardware optimization package distributed by CoralVue to ensure absolute sealing integrity and universal installation flexibility inside aquarium sump chambers. Automatic fleece rollers serve as a premium replacement for traditional cloth filter socks, continuously advancing non-woven fleece across the drain path to capture organic physical waste before it breaks down into nitrates and phosphates. However, while the industry uses "7-inch" as a standard classification for large-format mechanical filter sock trays, actual manufacturing thresholds vary significantly between brands. A socket tray from one manufacturer might measure exactly 6.9 inches inside, while another uses a wide 7.25 inches opening. If a drop-in roller fits too loosely or sits unevenly, pressurized water will bypass the filter entirely. This specialized multi-ring set completely eliminates this gap by providing swappable collar footprints tailored to secure your large-format roller frame perfectly.
Molded to meet precise structural metrics, the CV-KLIR-FSRING7 includes both the standard and expanded sizing collars used by the Klir Di-7 Automatic Fleece Filter series. The rings slide smoothly onto the lower tracking tracks of the filter's primary body frame. Over long periods of heavy operation, changing your filtration layout, or forcefully pulling the chassis during seasonal deep cleanings, these outer alignment rings can suffer structural wear, snap at the mounting seams, or get lost during home moves. Dropping this factory-spec adapter set onto your frame instantly secures a watertight seat, keeping your automated filtration working at peak performance without dumping detritus into your return chamber.
Key Features
Restores Absolute Frame Squareness: Eliminates rocking, tilting, and vibrations caused by trying to sit a standard filter frame inside an oversized sock hole opening.
Optimizes Smart Sensor Performance: Ensuring the frame sits level allows the internal water column to rise uniformly, preventing false optical level sensor alerts on your control box.
100% Reef-Safe Materials: Fabricated entirely from marine-grade polymers that will not alter your aquarium's surface tension or cause your protein skimmer to overflow.
(Note: This retail kit contains (2) alternative swappable structural adapter rings only. Complete Klir Di-7 automatic roller filter assemblies, replacement 50-micron fleece rolls, flexible silicone perimeter gaskets, and 12V DC motor blocks are sold under separate product categories).

- Unplug your automatic fleece roller filter's electronic smart controller from the wall outlet to prevent any accidental motor cycles during maintenance.
- Carefully lift the entire Klir Di-7 unit straight up out of your sump's filter sock tray opening and lay it flat on a dry towel.
- Remove your flexible silicone perimeter gasket and gently slide the existing plastic adapter collar downward off the lower retention channels of the filter frame body.
- Clean the matching mounting grooves on your filter housing with a warm vinegar cloth to clear away any hard, crusty salt creep or calcified mineral scale.
- Select the ring from the CV-KLIR-FSRING7 adapter set that matches the diameter of your sump hole. Slide the new ring upward into the frame channels until it locks firmly.
- Re-stretch your silicone gasket over the newly installed adapter ring track, lower the unit back down into your sump's 7-inch sock hole, and check for a snug, flush seating arrangement.
Pro Tips:
- Never Force the Filter Frame Down into a Tight Sump Opening. When testing your new collar configuration inside a tight acrylic or glass sock plate, never push down with heavy force or wedge the plastic collar into position. Forcing a rigid plastic adapter ring under extreme structural stress can cause the frame corner joints or the sump tray itself to develop micro-cracks ("crazing"). If the 6.9-inch ring is slightly too snug, use a fine piece of sandpaper to smooth down the inside lip of your sump tray opening rather than forcing the filter down.
- Always Couple these Hard Rings with a Flexible Gasket to Block All Leaks. Keep in mind that these hard polymer rings are designed to correct structural diameter clearances, not to form a flexible seal. To stop all unfiltered water bypass, always re-install your soft silicone perimeter gasket (SKU: CV-KLIR-DI7-GAS) completely over the adapter ring edge. The flexible silicone acts as a compression gasket, filling in micro-gaps between the hard plastic collar and your sump tray wall to ensure 100% of the water passes through your fleece.
- Keep the Unused Adapter Ring Stored Safely in a Dry Cabinet. Once you have determined which ring matches your current sump tank setup, take the remaining unused adapter collar, wrap it in a clean zip-top bag, and store it safely in your equipment cabinet. If you ever upgrade your large-volume aquarium setup, switch to a different sump manufacturer, or sell the automatic roller filter to another hobbyist down the road, having the alternative 6.9-inch or 7.25-inch fitting ring on hand ensures complete hardware flexibility.
