Compression fittings Ø 4mm to 15mm

The API Compression Fittings (Series O) provide a safe and reliable connection for metal, nylon, polyurethane, and rilsan tubes in compressed air and fluid systems. These fittings are designed for applications requiring high pressure resistance and a secure connection. They are made of 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, reducers, and banjo fittings. All fittings comply with DIN 3870-3861 standards and are suitable for pressures up to 60 bar, depending on the tube used. The single cone ogive ensures optimal sealing when tightening the nut.
