The HRC from HMA Flow & Industrial is a general-purpose coupling available in eight sizes in taper bush style or pilot bore. Alignment is achieved quickly by placing a straight edge across the outside diameter of the hubs.

No special tools are required, only a hex wrench for locking the taper bushes. The HRC from HMA Flow & Industrial accommodates incidental axial, parallel, and angular misalignment. The HRC is compatible with similar styles of couplings, while the insert is nitrile rubber.
