Adapters designed for plumbing systems facilitate connections between cross-linked polyethylene pipes of differing expansion methods. Specifically, they bridge PEX-A, which utilizes an expansion fitting method, to PEX-B, which relies on crimp or clamp connections. These components are often sought at major home improvement retailers. An example would be integrating a newer PEX-A manifold into an existing PEX-B system.
The significance of these connectors lies in their ability to allow for compatibility between different PEX systems, mitigating the need for complete system overhauls when extending or repairing plumbing. This approach can lead to cost savings and simplifies the modification of existing infrastructure. Historically, this type of flexibility was not inherent in plumbing systems, requiring more complex and often costly solutions.
