The McAlpine 42G-CB is a compression straight connector made from chrome-plated brass. It is similar to the McAlpine 35G-CB, but has a larger diameter to accommodate larger pipes or fittings. The compression fitting uses a compression nut and olive to create a watertight seal between the connector and the pipe or fitting. Like the 35G-CB, the chrome plating on the brass provides a durable and attractive finish that resists corrosion and tarnishing, making it suitable for use in a range of different environments. This type of connector is commonly used in plumbing and heating applications where a strong, reliable connection is required. Overall, the McAlpine 42G-CB Chrome Plated Brass Compression Straight Connector is a high-quality, reliable fitting that is well-suited to a variety of plumbing and heating applications where larger diameter pipes or fittings are required. ・ Available in 32mm (Euro), 1¼" and 1½" sizes ・ Sleek chrome compression nuts match Chrome Plated Brass trap nuts
