Segment Options
A V-retainer coupling exerts compressive force against flanges and can be a continuous, single ring (one-piece) or specified as two or more segments. Multi-segment couplings are recommended for most applications because of more uniform clamp loading and their inherent flexibility–for ease of installation and removal. Four popular segment options are shown here.
   

Single Segment

Single-segment couplings are lightweight and relatively economical. Due to the stiffness of a continuous ring, single-segment couplings are available only in larger diameters and for infrequent removal. Single segment couplings are usually provided with strap loops rather than a full band.

Two Segment

Two-segment couplings provide greater flexibility for ease of installation and removal. They are used on larger diameters. Two-segment coupling can be provided with two latches or with strap loops.

   

Three Segment

Three-segment couplings provide more flexibility for removal and installation and can be used for large and small diameters; it is the most useful and economical segment design configuration.

Four Segment

Four-segment couplings are used in large diameter applications where two- or three-segment couplings are not adequate. Four-segment couplings can be used with multiple latches and must be used with a full band.
