ARGCO's PUSH-ON rigid coupling is a truly rigid grooved pipe coupling which does not allow for any axial movement, angular movement and/or rotational movement under normal service conditions. 

Allows the pipe to move into the couplings directly without losing components. Support and hanging requirements correspond to ANSI B31.1, B31.9 and NFPA 13. 
All piping including mechanical rooms where no angular or axial movement is desired
