Rapid fittings in metal, plastic, and stainless steel

The API Rapid Fittings (Series C) provide a fast and secure connection for nylon, polyurethane, and rilsan tubes in compressed air and fluid systems. These fittings are designed for applications requiring a reliable tube-fitting connection. They are available in nickel-plated brass and support tube diameters from 4 mm to 15 mm, with BSP, BSPT, and metric thread options. The series includes straight connections, elbows, tees, banjo fittings, and special configurations such as swivel studs and bulkheads. All fittings comply with Reach and RoHS directives and are suitable for pressures higher than the tube itself and temperatures from -20°C to +90°C. Threads from M5 to 1/2″, pipes from Ø 4 to 15 mm
