Hex Couplings

Hex Couplings are stainless steel fittings used to connect two tubes or pipes of the same diameter in a straight line. The hexagonal shape in the middle provides a surface for a wrench, enabling easy tightening and assembly. They are widely used in instrumentation, hydraulic, pneumatic, and process piping systems for creating a strong, leak-tight connection.   Technical Specifications: a.
