Description

This 2-1/2 in. Female Adapter is made from 70/30 Copper Nickel with a Socket Weld x Threaded connection. 400 lb pressure rating.

Female Adapters are fittings that have female threads on one end. These are used to connect non-threaded or non-male components into a female component.

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.

70/30 Copper Nickel, often abbreviated to 70/30 CuNi, is a high-performance alloy comprised of 70% copper and 30% nickel. This high nickel content offers enhanced resistance to corrosion than other alloys- making it a critical material for producing marine and offshore systems components.
