Series 732 Transition for Ductile Iron Size PVC/HDPE Submittal

Transition Fitting for Ductile Iron Size PVC/HDPE

The transition fitting is constructed out of PVC material, ductile iron, and high density polyethylene (HDPE) 3408 pipe. The PVC and HDPE materials are joined together by hydraulically pressing the HDPE pipe into the ductile iron coupling. The coupling portion of the transition fitting is machined with our multi-level barb system that provides a leak-free radial compressed joint. The HDPE and PVC portions of the transition fitting are cut to a specific length and are pressed into the coupling.

Quality Assurance

The transition fitting shall be manufactured by Poly-Cam, Inc.  Poly-Cam, Inc. shall provide quality assurance with regards to proper installation, compatibility, performance, and acceptance. Transition joint meets or exceeds the requirements of ASTM D2513 Category 3.

System Performance

The transition fitting is designed to handle the pressure rating of the HDPE pipe with a 2:1 safety factor at 73.40 degrees Fahrenheit with a minimum 50 year design life.


Carbon steel coupling: The coupling is manufactured out of ductile iron.

The epoxy coating (IF 194T Red Iron Oxide) is fusion bonded to the metal. It has approvals NSF 61, FDA 175.300, AWWA C116-01, C213-01, UL 262 and FM 1120/1130

PVC SCH 35: PVC Gasket Sewer Pipe conforms to ASTM D-3034 in sizes 4 through 15”.

High Density Polyethylene: The transition fitting is constructed with a 3408 HDPE pipe (cell class 345454c) classified according to ASTM D3350.


HDPE pipe end

Install transition fitting to comply with the pipe manufacturer’s recommended procedures.  All field welds shall be accomplished per Plastic Pipe Institute’s welding procedure for butt fusion or electrofusion.

PVC coupling

Install the PVC coupling to comply with the pipe manufacturer’s recommended procedures for solvent cement.
