Total Crossed Beams

(Applied to the functional coverage of connection types)

Full performance coverage across multiple fitting shapes, tube sizes, and connector materials.

Ensures complete compatibility with any pneumatic layout—whether branching, distributing, splitting, or extending air circuits throughout a machine.

Engineered for consistent airflow, secure mechanical retention, and stable operation in diverse installation orientations.

Beam Pitch Options

(Translated as: tubing sizes, connection formats, material variants)

Available in a wide range of tubing diameters, thread types, and connection interfaces, ensuring perfect integration into any pneumatic system.

Options include:
• Tube outside diameters from small signal lines to large air-supply lines
• Thread types (metric, G-thread, R-thread, NPT depending on variant)
• Material variants such as brass, nickel-plated metal, polymer, and stainless steel
• Multiple shapes: straight, elbow, tee, cross, Y-splitters, reducers
• Tubes in PA, PU, and PE materials for flexibility, durability, or chemical resistance

These choices allow the system to be tailored for compact routing, high-pressure conditions, harsh environments, or flexible installation paths.

⭐ Important: The broad variety of fittings and tubing ensures optimal flow distribution and connection reliability for any pneumatic architecture.
