Garbage disposal splash guards: QCB-AM vs SMG-OO vs Waste King ~3⅛"

When the rubber flaps tear, harden, or smell, you buy a replacement sink baffle / splash guard — not a new disposer. Shoppers often order “InSinkErator splash guard” by brand look-alike and get an Evolution Quiet Collar that will not seat in a Badger flange, or a Badger mounting gasket that is the wrong OD for a Waste King EZ-Mount. This page helps you match QCB-AM / Quiet Collar (~3⅜" removable, Evolution), SMG-OO / 09963D (~3.88" Badger-family mounting gasket), and Waste King / Whirlaway / GE ~3⅛" removable baffles to the disposer on the sink and the old part, then reorder Amazon-available guards.

Who needs this

• InSinkErator Evolution owners whose Quiet Collar flaps are torn, stiff, or hard to clean
• Badger 1 / 5 / 5XP / Septic owners hunting SMG-OO / 09963D after a leaky or shredded under-flange gasket
• Waste King / Whirlaway / GE EZ-Mount owners needing a ~3⅛" removable baffle or 1025-class stopper+guard
• Anyone who ordered a “universal disposal splash guard” that sits too small or too large in the sink opening
• DIYers measuring the old baffle OD and matching OEM crosses before Amazon reorder

How to choose (measure, model, part number, when to replace)

1. Measure the old baffle OD (and note whether it pulls out from above or sits under the mounting flange). Write the number before you discard the torn rubber.
2. Read the disposer model on the unit label / rating plate (Evolution vs Badger vs Waste King / GE / Whirlaway) and any part number on the old guard.
3. Pick the family — QCB-AM, SMG-OO, and ~3⅛" EZ-Mount are not interchangeable by “splash guard” alone.
   • QCB-AM / Quiet Collar: removable antimicrobial baffle for Evolution series; listings ~3⅜" / ~3.4" (some OEM charts cite ~3.25" class). Push-in from above; not for Badger. Strong Amazon aftermarket presence (e.g. B09NR5RBKH / B09XCHCXPC-class titles).
   • SMG-OO / SMG-00 / 09963D: standard Badger-family splashguard/mounting gasket ~3.88" / ~3-⅞" OD. Fits Badger 1, 5, 5XP, Pro 333, Septic, and related ISE mounts. Often requires dropping the disposer to replace under the flange — not a drop-in Quiet Collar.
   • Waste King / Whirlaway / GE EZ-Mount ~3⅛": removable baffles ~3.125"; Waste King 1025 stopper+splash-guard kits and Amazon 3-1/8" multipacks (e.g. B0B3WNKV6J-class). Not Evolution QCB-AM and not Badger SMG-OO.
4. Watch brand look-alike listings. “Fits InSinkErator” alone can mix Evolution Quiet Collars with Badger mounting gaskets. Prefer titles that list QCB-AM, 09963D / SMG-OO, or exact 3-1/8" / 3⅜" OD.
5. Replace when flaps tear or harden. Cleaning helps odor; a new baffle is for torn flaps, warped rubber, or a gasket that no longer seals splash.
6. Confirm Amazon listing crosses. Prefer titles that list your exact OEM number or measured OD. Ignore “universal disposal splash guard” alone.

FAQ

Is QCB-AM the same as SMG-OO / 09963D?

No. QCB-AM is a removable Quiet Collar for Evolution (~3⅜" class). SMG-OO / 09963D is a ~3.88" Badger-family mounting gasket, often under the flange. Wrong OD / wrong mount = leaks or a baffle that will not seat.

Why did my “InSinkErator splash guard” not fit?

Many Amazon titles say InSinkErator without Evolution vs Badger. Quiet Collar and Badger mounting gaskets look similar in photos. Measure OD and match the old part number or disposer series.

Do I have to drop the disposer to replace the baffle?

QCB-AM and many Waste King / GE removable baffles pull from above. Badger SMG-OO-style mounting gaskets often sit under the flange and may need the disposer dropped — check your install before ordering “easy pull-out” only.

Will a 3⅛" Waste King baffle fit Evolution?

No. Evolution Quiet Collar openings and Badger ~3.88" gaskets are different families. Use QCB-AM for Evolution, SMG-OO for Badger, ~3⅛" for Waste King / Whirlaway / GE EZ-Mount.

How is this different from refrigerator water filters?

Fridge pages cover dispenser cartridges. This page is for sink splash guards / baffles on the disposer opening — a size/fit rubber replacement part, not a water filter.

Quick reorder checklist

• Measure old baffle OD (and note pull-out vs under-flange)
• Write disposer model from the unit label (Evolution / Badger / Waste King / GE)
• Read old part number if visible (QCB-AM, SMG-OO, 09963D, 1025, etc.)
• ~3⅜" / ~3.4" removable Evolution → often QCB-AM Quiet Collar
• ~3.88" / ~3-⅞" Badger mount → often SMG-OO / 09963D (plan for possible disposer drop)
• ~3⅛" / 3.125" EZ-Mount → Waste King 1025-class / 3-1/8" packs
• Skip “universal InSinkErator splash guard” unless OD + series match
• Replace when flaps tear or harden; clean as needed either way
