Klir Automatic Fleece Filter Di-7 Replacement Silicone Gasket (SKU: CV-KLIR-DI7-GAS)
The Klir Automatic Fleece Filter Di-7 Replacement Silicone Gasket (SKU: CV-KLIR-DI7-GAS) is an authentic mechanical OEM replacement sealing component distributed by CoralVue to guarantee total water processing security inside your sump chamber. Drop-in automatic roller filters provide a massive efficiency upgrade over traditional cloth socks, continuously advancing a 50-micron fleece roll to lift organic waste entirely out of the water column before it breaks down into nitrates and phosphates. However, because a drop-in unit relies on a flush physical seal with your existing 7-inch filter sock tray panel, the system requires a baseline buffer seal. Without a flexible gasket surrounding the perimeter rim, water will naturally take the path of least resistance, flowing under the mounting plate and dumping raw detritus right into your clean return pump chamber. This premium silicone gasket slips tightly over the collar tracking slots to create a secure barrier, ensuring your water is fully polished.
Molded to meet precise engineering dimensions, the CV-KLIR-DI7-GAS is engineered to handle persistent exposure to high-velocity sump water, aggressive salt creep, and regular maintenance pulling. Over several years of operation, the original factory gasket can stretch out of shape, develop fine micro-tears from sharp edge friction, or go missing during a routine seasonal deep clean. Replacing a damaged or missing ring with this factory-spec silicone gasket immediately re-establishes a watertight seat, keeping your automated filtration system running at peak performance.
Key Features
Forces 100% Core Fleece Processing: Stops physical fish waste, uneaten food flakes, and floating algae from sliding around the collar rim through loose gaps.
Cushions Dynamic Sump Vibrations: Absorbs hard harmonic vibration frequencies transferring from high-output return pumps, keeping your filter stand completely quiet.
Snug Slip-Prevention Hold: Provides critical surface friction against acrylic or glass sock trays, preventing the roller chassis from shifting or unseating under high-flow surges.
(Note: This retail SKU contains (1) standalone replacement 7-inch silicone collar gasket. Complete Klir Di-7 automatic roller filter frames, swappable sock tray adapter collars, 12V DC motor blocks, and replacement fleece rolls 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.
- Roll the old, stretched, or torn gasket downward off the plastic flange collar and discard it.
- Take a soft cloth soaked in warm white vinegar and wipe clean the perimeter tracking channel of the collar rim to remove hard, crusty salt creep or calcified mineral buildup.
- Unpack your fresh CV-KLIR-DI7-GAS silicone gasket and stretch it gently over the base of the lower collar. Align the gasket so it seats flat inside the molded tracking groove without twisting.
- Verify the gasket sits perfectly uniform with zero bunching, then carefully lower the Klir Di-7 unit back down into your sump tray's 7-inch sock opening, checking for a flush, snug fit.
Pro Tips:
- Never Apply Adhesives, Superglue, or Household RTV Silicone to Secure the Gasket. When installing this fresh replacement seal onto your Di-7 framework, never use cyanoacrylate superglues, liquid silicone adhesives, or tape to anchor it into the track. This gasket is designed to hold its position purely via engineered elastic tension. Gluing the ring down makes it impossible to remove later when performing routine chassis tear-downs, permanently ruining your modular mounting components.
- Ensure the Ring is Not Twisted Inside the Track to Prevent Frame Wobble. As you stretch the flexible silicone band over the plastic frame, run your thumb along the entire perimeter to verify that the ring sits perfectly flat inside the groove. If the silicone ring is twisted or rolled over on itself in one section, it will create a high spot. This unlevel spot will cause the entire filter roller to sit tilted inside your sump tray, resulting in a wobbly frame, loud vibration noises, and potential bypass paths on the opposite side.
- Soak the Gasket in Warm Vinegar to Easily Clear Off Calcified Mineral Scale. During your semi-annual filter deep cleanings, pull the silicone gasket completely off the frame and drop it into a cup of warm, household white vinegar for 15 minutes. Over several months, splashing aquarium water will deposit hard layers of calcium carbonate scale onto the smooth silicone surface. This mineral scale hardens the flexible material, causing it to lose its sealing grip. A quick vinegar soak dissolves the scale and completely restores the silicone's original flexibility.
