Figure 616 Reducing Coupling is for joining copper tubing systems. 

The Gruvlok Figure 616 Reducing Coupling allows a direct reduction between two different CTS copper tubing sizes and eliminates the need for a concentric reducer and couplings.

The epoxy coated ductile iron coupling housings help to eliminate local galvanic cell and stray current problems. A specially designed rubber gasket prevents the smaller tube from telescoping into the larger tube during vertical installation.
