Compression couplings

Compression couplings are mechanical devices that connect two shafts or pipes, allowing for torque or fluid transmission while accommodating slight misalignments. They consist of a cylindrical body with screws or bolts that compress the coupling onto the shafts or pipes. Commonly used in plumbing, HVAC systems, and machinery, compression couplings are effective for connecting pipe sections in fluid transfer and in power transmission systems where alignment may vary due to thermal expansion. These couplings comply with standards such as ASTM A307, which outlines requirements for carbon steel bolts and screws used in compression coupling assemblies. Well-known manufacturers like CPC, Misumi and Yiheda offer their 3D CAD models on 3Dfindit, including compression couplings.
