Watts 718008 – Frequently Asked Questions
1) What pipe size does the Watts 718008 Blueline coupling fit?
The 718008 is a 4 inch coupling. It joins two 4 inch Blueline FRPP pipe ends, with a 0.38 inch wall thickness on the fitting body. If your run is a different diameter you need the matching size in the RFCF coupling series, not this one.
2) How does a Watts Rionfuse coupling join the pipe, and do I need special tools?
Rionfuse is the connection method on the 718008, an electrofusion style joint rather than a threaded or solvent weld connection. The joint is made by fusing the coupling to the pipe, so you need the Rionfuse fusion equipment on site. Plan for that before the fitting lands on the job: there is no glue-and-go or thread-on option with this coupling.
3) Can I use the 718008 coupling to connect FRPP pipe to PVC or cast iron?
No. This is a fusion coupling built to bond FRPP to FRPP. Solvent cement will not bond polypropylene, and the Rionfuse joint has no mechanical or threaded engagement for dissimilar material. To tie an FRPP acid waste line into PVC or cast iron you need a proper transition fitting or a mechanical coupling rated for that changeover, not this part.
4) What is the Watts part number to order for a 4 inch Blueline Rionfuse coupling?
Order Watts 718008. That is the manufacturer part number for the 4 inch Rionfuse coupling in the Blueline FRPP line, and it is the only model on the item, so there are no finish, end-type, or handing options to specify with it.
5) Is the 718008 a straight repair coupling or does it change direction?
Straight coupling. It is an inline joint between two 4 inch FRPP pipe ends and does not change direction or size. For a turn or a branch, specify an elbow, wye, or tee from the same Blueline FRPP fitting range.
