Product specification

The Model AJ320 Flexible Coupling is designed for use in a variety of general piping applications of moderate or high pressure services.
The Model AJ320 couplings feature flexibility that can accommodate misalignment, distortion, thermal stress, vibration and noise and also resist seismic tremors. The utilization of Model AJ320 couplings can accommodate a curved layout.
The Model AJ320 couplings are comprised of two housing segments, EPDM gaskets and plated track bolts and nuts.
AJ320 couplings should always be installed so that the coupling bolt pads make metal to metal contact.


Material specification

  • Housing: Ductile Iron to ASTM A536, Gr. 65-45-12, min. tensile strength 65,000 psi (448 MPa)
  • Surface Finish: Epoxy Coating
  • Rubber Gasket: Grade EPDM approved under NSF/ANSI 61.
  • Bolts & Nut: CS for machine structural use.
