AC, AD, and T-type male tees feature a 24° tapered female tee thread, designed to form a tight, leak-proof connection with the pipe end. This tapered thread design enhances sealing performance and ensures stable engagement with mating components, even under high-pressure conditions.

These fittings support two standard pipe diameter ranges compliant with DIN 2353: 24° tapered light-duty fittings (06L–42L), designed for weight and space efficiency in light industrial applications such as automated production lines; and 24° tapered heavy-duty fittings (06S–38S), whose enhanced durability is suitable for heavier-duty applications in oil/gas processing or large-scale manufacturing. Additionally, reducing tee fittings are available, further expanding compatibility to accommodate a wide range of pipe sizes in complex fluid systems.
With maximum pressure ratings up to 630 bar (9,000 PSI), AC, AD, and T-type male tee fittings excel in high-risk applications and maintain stable performance under extreme loads. Combining rugged construction, global compliance, and flexible connectivity, they are the trusted choice for professionals seeking reliable, efficient branch connections in high-performance fluid systems.
To ensure universal quality, compatibility, and safety, AC AD T male tees conform to DIN 3861 and ISO 8434 international standards.
