Bulkhead connectors are essential for creating secure, leak-free connections when passing pneumatic tubing through panels or enclosures. Commonly used in air brake systems, these fittings ensure the integrity of the pneumatic circuit by providing a stable and protected routing point for air lines. Their design minimises tubing stress and prevents kinking, offering a tidy and reliable solution for industrial applications where lines must traverse a barrier. They are crucial for system efficiency and safety.
