40 INSTALLATION INSTRUCTIONS HDPE Couplings
Figure 9097 HDPE Transition Coupling
• WARNING
Always read and understand the instructions including the “Installation Guidelines” provided on page 15. Failure to follow these instructions may result in improper product installation, joint failure, leakage, serious personal injury, and/or property damage.
The following instructions apply to the Figure 9097 HDPE Transition Coupling as described in technical data sheet G582. The coupling is designed to join high-density polyethylene (HDPE) to IPS steel pipe of the same outside diameter. The HDPE pipe is to conform to ASTM D2447, D3000, D3035, or F714 (metric sizes to ISO 161/1, DIN8074, and AS8074), at ambient temperatures with wall thickness from SDR 7.3 to 32.5. The IPS pipe is to be grooved in accordance with Standard Cut Groove or Roll Groove Specifications. Refer to Technical Data Sheet G710 for more information.
The Figure 9095 HDPE Coupling is not intended for use on anything other than HDPE piping. Refer to Technical Data Sheet G582 for addi- tional information.
Step 1. HDPE pipe must be cut square. The maximum allowed tolerances are 0.125 inch (3.2 mm) on HDPE pipe sizes 2 inch to 4 inch and 0.156 inch (4.0 mm) on 6 inch and larger sizes. Make sure that the pipe end, within 1 inch from the end, is clean and free from indenta- tions, projections, scratches or other harmful surface defects such as scale, chips, and grease.
Step 2. Use a marking pen or other marking tool and measuring tape to place a mark 1 inch from the HDPE pipe end.
Step 3. Cover the sealing edges and outer sur- faces of the gasket with a fine layer of lubri- cant. Use a petroleum-free silicone-based lubricant such as Dow Corning* No. 7 Release Compound.
• Place the gasket over the pipe, ensuring that the gasket lip does not extend beyond the end of the pipe.
• Bring both pipe ends together, ensuring proper alignment.
•Slide the gasket into position, properly centering it between the mark on the HDPE pipe and the groove of the IPS steel pipe.
