The MJ Adaptor DI
MJ Adaptor Transitions

The POLY-CAM MJ Adaptor Transition is a double restraint multi-level mechanical transition fitting, protected under patent number 5,211,429, which is hydraulically compressed unto the polyethylene or pipe quality copolymer material.

Design
The relaxation creates a seal to prevent leakage. Under pressure, the internal pressure within the pipe increase the sealing surface area on the barb. Under zero internal pressure, the compression strain and tensional strain created by the compression of the multi-level barbs is greater then the stress created by relaxation and/or thero expansion and contraction. As the internal pressure increases the joining of the polyethylene or copolymer and the coupling increases. This product required use with Mega-lug or Field Lock Gasket. Standard Glands will not completely restraint the expansion conation of the HDPE. This design allows end user to use standard bolt length instead of special costly longer bolts. It also allows not waiting time for back fill. Sizes range from 3” to 24” in both iron and ductile pipe

Sizes range from 1” to 24” Iron Pipe Sizes.

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.

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 11 and ANSI/AWWA standard C-906.

Installation
HDPE pipe end: Install transition fitting so as to comply with the pipe manufacturer’s recommended procedures. All field welds shall be accomplished in accordance with Plastic Pipe Institute’s welding procedure for butt fusion.

Ductile Fitting
: The entrance of the coupling is tapered at the beginning. The Polyethylene or copolymer material is cold pressed into the coupling. This allows the material to relax into the patented multi-level barb system.

Material
Ductile Iron/HDPE: The POLY-CAM Threaded Transition is manufactured of American made cast ductile iron and incorporated with the transition manufactured of HDPE PE 3408 (cell class 345454c) or pipe quality Copolymer material. All certification will be submitted upon request. All parts are manufactured in United States and comply with American Recovery and Reinvestment Act of 2009.

Stainless Steel Insert: The insert are manufacture out 304 stainless steel tubing (ASTM A249 or ASTM A269) and or ERW pipe (ASTM SA-312).

Warranty
Warranty period is one year after date of substantial completion of installation.
