ProPex Expansion Heads

PEX tubing, known for its flexibility and ease of use, has revolutionized plumbing. But these pipes require a unique connection method – PEX expansion. This innovative technique utilizes an expansion head to create a secure, long-lasting connection without the need for soldering, brazing, or harsh chemicals. Here's a breakdown of how PEX expansion heads work: The Power of Expansion: PEX expansion heads are compact tools powered by a cordless drill or dedicated PEX expansion crimping tool. They house a set of expandable pins or wedges specifically designed for various PEX pipe sizes (commonly used sizes in Ohio include ½ inch, ¾ inch, and 1 inch). When activated, the tool pushes these pins outward, expanding the PEX tubing from the inside. Creating the Seal: The key to a secure PEX connection lies in the PEX expansion sleeve. This metal ring fits around the PEX pipe and has an inner diameter slightly smaller than the unexpanded pipe. When the expansion head expands the PEX tubing, it creates a tight fit within the sleeve. As the PEX material contracts back to its original size after the expansion, it forms a strong grip around the fitting inserted into the expanded section. This gripping action creates a watertight seal, ensuring a reliable and leak-proof connection. Applications and Benefits: PEX expansion heads are a favorite among plumbers and DIY enthusiasts due to their speed, ease of use, and affordability. They are ideal for various plumbing applications, including installing water supply lines for sinks and fixtures, running PEX for radiant heating systems, or rerouting plumbing lines during renovations. The expansion method eliminates the need for open flames or hot work permits, making it a safer alternative for indoor plumbing projects. PEX expansion heads empower users to create secure and long-lasting PEX connections, simplifying plumbing tasks and saving time on projects throughout Ohio.
