Compression Fittings
POOLKE Brass Compression Fittings are designed for secure and reusable tube connections in pneumatic, fluid and industrial piping systems. The compression sealing structure provides reliable tube retention without requiring welding or special assembly equipment, making installation and maintenance easier across a wide range of machinery and process applications.
The product range includes CN, CP, CB and other configurations with straight, elbow, tee, bulkhead, union and multi-port connection styles. Depending on the series, tube sizes cover approximately 4–24 mm together with inch sizes, while BSPP, BSPT, NPT and metric thread options support different international piping standards. The Brass Compression Fittings are available in different structural and material configurations to meet varying pressure, temperature and tube requirements. The catalog lists maximum working pressures up to 5 MPa for selected series, while specific temperature ranges vary according to fitting material and tube type. Their compact design, strong pressure resistance and broad connection selection make them suitable for pneumatic automation, industrial machinery and general-purpose fluid systems.
