These gas posts feature a distinctive score or strike to help easily identify them. Specifically, a gas ball lock will only be compatible with a gas ball lock post, and likewise, a liquid ball lock will only fit on a liquid ball lock post. This ensures a secure and accurate connection for your system. 

The package includes a high-quality Ball Lock Post O-Ring, which is essential for a proper seal and optimal performance. Please note that the poppet is not included, and will need to be purchased separately for full functionality. 

These gas posts are designed for durability and are perfect for use in homebrewing or kegging setups. Be sure to check your system’s requirements before purchasing to ensure compatibility.
