Sch 80 CPVC nipples are light gray in color like the pipe and fittings. All CIS nipples are sourced from Spears and other top manufacturers. They use NPT (National Pipe Thread) threads to ensure correct connection between all your CPVC fittings.
The measurements (in inches) in the nipple name on our site indicate the size and the length of the part. For instance, a 2” x 6” CPVC nipple (part number 9861-265) is 2” nominal pipe size and is 6” long.
