What does IPS stand for in plumbing?
Iron Pipe SizeIron Pipe Size (IPS) refers to an old pipe sizing system still in use by some industries, including major PVC pipe manufacturers, as well as some legacy drawings and equipment. The iron pipe size standard came into being early in the 19th century and remained in effect until after World War II.

Can you over tighten NPT fittings?
If the connection leaks after re-assembly, you may need to replace one or more of the fittings. … Over-tightening the connection can easily split the female portion of a pipe thread connection; this is especially an issue when installing male pipe thread fittings into cast iron ports on valves, motors, and cylinders.

What is CV in plumbing?
The flow coefficient, or Cv, is a universal capacity index and is simply defined as “the number of US gallons of water per minute at 60F that will flow through a valve with a pressure drop of one psi. Sometimes “pressure drop” is described as pressure differential or “delta P”.
Is NPT male or female?
NPT has a tapered male and female thread which seals with Teflon tape or jointing compound. Pipe threads used in hydraulic circuits can be divided into two types: Jointing threads are pipe threads for joints made pressure tight by sealing on the threads and are taper external and parallel or taper internal threads.
