Features

  • Reducer coupling for connecting two pipes of different sizes going in the same direction
  • Female National Pipe Taper (NPT) threads on both ends for connecting two male threaded pipes of different sizes

  • National Pipe Taper (NPT) threads for creating tighter seals than straight threads

Description

The Anvil reducer coupling is a class 150 malleable iron pipe fitting with female National Pipe Taper (NPT) threads on both ends to connect two male pipes of different sizes going in the same direction. The coupling has NPT threads for creating tighter seals than straight threads. It is made of malleable iron, which has high tensile strength, and has a black finish that resists rust in oil and gas applications. This class 150 fitting meets standards ASTM A-197, ASME B 1.20.1, and ASME B 16.3 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).Anvil International provides pipe products and design services. The company, founded in 1850 and headquartered in Portsmouth, NH, meets International Organization for Standardization (ISO) 9001:2000 standards and is certified by the American Petroleum Institute (API). Its fittings meet American Society for Testing and Materials (ASTM) and American Society of Mechanical Engineers (ASME) specifications.

  • USA made fittings...
It is just a pipe fitting, so not much to evaluate. BUT, it is made in USA and the threads are much smoother and even than the imported fittings at the big box stores (and most hardware stores). Most imported fittings I have used have gaps in the threads, not so with the Anvil brand fittings I have gotten from Amazon. ... show more

  • Good quality

After ordering several iron pipe pieces from other companies manufactoring them in China, I can tell the better quality of this piece from the US. Nice build and finish with no jagged edges. Will definitely buy from this company again.

Good stuff here but way too expensive which is why one star less. I think this price can be 50% less at least and still make a profit for the manufacturers. Unfortunately you cannot find these anywhere else online, hence the exorbitant price. Great for steampunk light socket housing for a 3/4" black pipe lamp. ... show more

Size: 2" x 1-1/2" Number of Items: 1
This is the very necessary reducer coupling when dealing with the cast iron p-trap/leg to hold both the Kohler and American Standard cast iron service sinks. Used when changing to a larger diameter base that bolts to floor or adding height, necessary to change from 1 1/2" to 2' for taller pipe/taller sink. VERY DIFFICULT TO FIND REDUCER as most common hardware stores don't carry this larger diameter pipe fittings. ... show more
