A reducer insert adapts a larger socket connection to a smaller pipe connection. Its geometry must match both the receiving fitting and the smaller pipe.
Reducer inserts are used as part of a socket-fitting arrangement when a smaller connection is needed. The insert provides the transition at the socket instead of using the body form of a separate reducing coupling.
The receiving fitting, insert and pipe must be considered as one connection arrangement. The outer interface and inner connection are both relevant to the selection.
General background for the explanation above. The project specification governs the actual selection.
02 / CONSTRUCTION
Two interfaces. One connection arrangement.
01
Receiving-fitting interface
The insert’s outer interface fits the intended larger socket in the receiving fitting.
02
Smaller-pipe connection
The inner connection receives the smaller pipe. Both interfaces belong to the complete arrangement.
03 / PRODUCT KNOWLEDGE
Understand a transition within the socket.
Reducer insert versus reducing coupling
An insert adapts the socket of another fitting. A reducing coupling is a separate fitting body that joins different connection sizes in line. The transition occurs in a different part of the connection arrangement.
It works as part of an arrangement with a receiving socket fitting and a smaller pipe. The receiving socket and the smaller connection both matter.
Why describe the receiving fitting as well as the pipe?
The insert has an outer interface to the fitting and an inner connection to the pipe. Identifying only the smaller pipe does not describe the complete fit.
04 / SELECTION CONSIDERATIONS
What matters in the application.
01
Receiving socket
Identify the fitting and socket into which the insert is intended to fit.
02
Smaller connection
State the required pipe connection and relevant mating pipe information.
03
Assembly definition
Include the required insert design or drawing reference. Confirm the complete arrangement against the project specification.
