Zurn Model FP23 Couplings are listed to join grooved pipes together. FP23 couplings are available with Rigid or Flexible options, or for Reducing connections.
Rigid Couplings provide sturdy inflexible joints comparable to flanged, welded, or threaded connections. They are designed to prevent angular and axial deflection of connected pipes.
Flexible Couplings allow joints to flex at the connection without leakage. They meet flexure requirements for structural setting inter-building piping, and seismic motion.
Reducing Couplings provide a flexible style joint between pipes of different sizes. Each Reducing Coupling makes a connection that would otherwise require two separate couplings and a reducer.
