38 INSTALLATION INSTRUCTIONS HDPE Couplings
Figure 9095 HDPE 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 9095 HDPE Coupling. They are designed to join high-density polyethylene (HDPE) pipe conform- ing to ASTM D2447, D3000, D3035, or F714 (metric sizes to ISO 161/1, DIN8074, and AS8074), at ambient temperatures with wall thickness from SDR 32.5 to 7.3.
The Figure 9095 Coupling is not intended for use on anything other than HDPE piping. Refer to Tech Data Sheet G580 for more 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 indentations, 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 marks on each pipe end, 1 inch from each 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 marks on each pipe.
The pipe ends should always be butted together. Lubricate the back of the gasket as well as the sealing edges.
