Description

This 5 x 4 in. Bushing is made from 90/10 Copper Nickel with a Socket Weld connection. Reducing. 400 lb pressure rating.

A pipe bushing is a reducing fitting used to joining two different sizes of pipe. Also called inserts or insert bushings, they can also be used to join pipes that have differing connection types. They are primarily used as adapters in fluid systems, making them standard components across a range of marine and industrial systems.

Socket weld pipe connections are used in high temperature and high-pressure environments. Socket weld pipe connections feature a smooth internal bore sized to match the outer diameter of the pipe. The pipe end is inserted into the socket and then fillet welded around the joint, forming a strong, leak-tight seal. Socket weld connections are popular in smaller sized fittings and are permanent.

Commonly abbreviated as 90/10 CuNi, 90/10 Copper-Nickel is a high-performance alloy comprised primarily of 90% Copper and 10% Nickel. This widely-used alloy provides an effective balance of strength, corrosion resistance, and cost effectiveness. 90/10 Copper-Nickel is a standard material for a variety of fluid systems that handle seawater - making it essential for marine applications.
