CPVC Nipples is used mainly on threaded pump connections. The threads present in these nipples can be both machined and molded but in most of the CPVC nipples the threads were mostly machined, which helps in ensuring a tight fit. These CPVC nipples are also graduated. CPVC nipples greatly reduce the problems with drip leaks or air leaks at the intake and outlet of the pumps. CPVC material has comparable corrosion resistance to PVC yet it is suitable for handling corrosive material at temps 40° - 60° F higher than PVC. CPVC nipple was used in a variety of industrial applications where a high functional temperature and resistance to corrosive chemicals are desirable.
