FerMonster Carboy Replacement Lid O-Ring – Food Grade Silicone

Description

Maintain an airtight fermentation environment with the FerMonster Replacement Lid O-Ring. Designed specifically for the wide-mouth FerMonster carboys, this food-grade silicone seal prevents oxygen from entering your fermenter and CO2 from escaping. Over time, original gaskets can stretch or absorb odors; this fresh replacement ensures your airlock stays bubbling and your beer stays protected.

Maintenance Tip: To ensure a perfect seal without bunching, apply a light coat of food-grade silicone lubricant (Keg Lube) to the O-ring before threading the lid on. Hand-tighten only—the gasket provides the seal, so excessive force is not required.
