Given by the name, you may have figured out the purpose of a “Close Nipple.” The use of a close nipple allows you to create a closed, tight connection between two female threaded steel pipes or fittings.
Sch 40 PVC couplings are used to join two pieces of pipe. Couplings come with socket or threaded ends. ... You can use couplings to reduce a PVC line so that you can regulate the flow and pressures in the PVC line or system. Couplings meet ASTM D 1784 and ASTM D 2466 standards and are suitable for potable water service.
What is a reducer coupling?
A coupling can be a reducer, or reducing coupling, meaning they reduce flow by joining a larger pipe to a smaller size. ... For example, an adapter could be fitted on the end of a plain pipe to allow a threaded connection at the other side of the adapter.

How do I reduce PVC pipe size?
Apply heat to the PVC with a heat gun until the PVC softens. Then, slide the other clamp onto the pipe and tighten both clamps to close the four cuts (above right). After the PVC cools, remove the clamps and check the fit. If the pipe is still a bit large, cut more slits and repeat.Jul 1, 2019

Does PVC pipe shrink when heated?
Like all materials, PVC expands with increasing temperatures and contracts with decreasing temperatures. ... A good rule of thumb in design of PVC pipe and conduit systems is to allow 3/8” length variation for every 100 feet of pipe for each 10°F change in temperature.
How do you remove a broken threaded PVC nipple?
mlarson: Use a small saw(coping blade or hack saw blade) to cut a slot in the broken plastic nipple. Be careful not to cut into the thread of the el fitting. Then use an awl or a long thin screwdriver to pry the remaing plastic out.Oct 12, 2007
