Before Talking about kitchen sink plumbing parts, you should know types of kitchen sink plumbing pipes.
1- ABS (acrylonitrile butadiene styrene) (Black plastic pipe) ABS is better in cold weather.
2- PVC (chlorinated poly-vinyl chloride) (White plastic pipe) PVC is better for outdoors and warmer climate applications.
PVC pipes will generally last longer than ABS. But, many plumbers prefer to use ABS because it is easier to work with when it comes to gluing it, ABS does not require a primer and the glue set much faster.
