Which method is commonly used to secure PEX tubing?

The use of crimping is a common and effective method for securing PEX tubing. In this technique, metal rings, often made of copper or stainless steel, are used to secure the fittings onto the PEX pipe. A specialized crimping tool compresses these rings around the tubing and fitting, creating a watertight seal. This method is popular because it ensures a strong connection that can withstand various pressures without leaking.

Crimping is also favored for its simplicity and reliability in installation, especially in residential plumbing applications. It's important for individuals handling PEX to familiarize themselves with proper crimping techniques, as an improperly crimped joint can lead to failure and water leaks.

The other methods listed are not appropriate for securing PEX tubing: welding involves high heat and is unsuitable for plastic materials like PEX, screwing is not typically utilized in PEX systems, and resting does not provide any fastening or connection; thus, these are not viable methods for securing PEX.
