Reducing Couplers

Reducing Couplers are the perfect solution for transitions from multiple sizes of PVC pipe into Concast Pull Boxes and Handhole units.  Concast's RC41 HDPE couplers fit into their 4 inch Con-Duct terminations.  They can be cut to fit the following PVC pipe sizes: 1 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, and 3.5 inch.  

Concast is now offering a new line of mechanical seals utilizing segmented ring technology for pipes.  They are completely gastight and watertight.  The PHPS line are designed for use with PVC, GRC and Cast Iron Pipe OD's.
