CO₂ Washer, Heavy-Duty Hard Plastic

Ensure a gas-tight seal and prevent costly leaks with our Hard Plastic CO2 Washer. Designed to sit securely between your CO2 tank outlet and the primary regulator, this small but essential component is the first line of defense against "empty tank syndrome." Made from durable, high-density plastic, these washers are built to withstand the high-pressure environment of a draft system. While many regulators require these for a proper connection, they are easy to swap out and replace during tank exchanges to ensure your carbonation remains consistent and your CO2 stays in the bottle, not in the air. Pro Tip: Check your regulator before installing. If your regulator features a built-in rubber O-ring (such as the Taprite dual-gauge models), an additional plastic washer is not required.
