Product Description

The A.Y. MCDONALD 5426-021 is a push-on removable male adapter designed for connecting CTS (Copper Tube Size) pipe to male pipe thread fittings. Constructed from brass, this 1 inch fitting provides a tool-free push-on connection that can be removed and reused, making it well suited for gas distribution, water service, and similar plumbing applications. The CTS x MPT configuration accommodates standard tubing-to-threaded transitions. Licensed plumbers and utility contractors install this type of adapter where a reliable, serviceable connection is required without soldering or crimping.

This adapter is used in residential and light commercial plumbing and gas service work wherever a 1 inch CTS line must transition to a male pipe thread fitting. The push-on, removable design supports applications that may require future access or line modification. It is a common fitting choice for meter sets, service line connections, and distribution manifold work.
