Urethane Bottle O-ring

This polyurethane seal is a top-tier choice for anyone looking for long-lasting performance when using CO₂ bottles and pressure regulators. Unlike standard rubber O-rings, polyurethane is harder and much more resistant to the extreme cold that occurs during CO₂ release. That means no cracking or breaking even under heavy use and low temperatures.

Although it comes at a slightly higher price, its significantly longer lifespan more than makes up for the cost—especially if you regularly use CO₂ systems.

Please note: Due to slightly different dimensions, this seal is not compatible with markers like Spyder (e.g. bolts or hammers). It is specifically designed for sealing external parts of CO₂ valves and high-pressure bottles.
