PVC/CPVC/PE nipples furnished may be produced from extruded stock, or from molding grade PVC/CPVC compounds. Both processes provide quality products meeting ASTM requirements.

These are referred to as Plain (no threads), TOE (Threaded One End), TBE (Threaded Both Ends), Grooved (which can be Plain x Groove, Groove x Thread, & Groove x Groove). Special varieties of polyethylene nipples include Cut-off, Four-In-One Cut-off and Four-In-One Cut-off Reducing. Close nipples are simply two (2) threads back to back. Short nipples is a term commonly used to designate a slightly longer nipple that is usually the smallest length above "close". The following table shows length of close and short nipples.
