About PEX Poly Expander F1960 Plugs
A PEX poly expander plug refers to a specific type of plug used in plumbing systems that is designed for capping off a section of polyethylene (PEX) piping. It is called a "poly expander" plug because it is intended for use with PEX tubing and utilizes the expansion method of installation. It is also referred to as a PEX A fitting.
The term "expander" indicates that this plug is installed using a specialized tool that expands the PEX tubing temporarily. The expanded tubing allows for easy insertion of the coupling, and as the tubing contracts back to its original size, it creates a secure and watertight connection. The sizes available are 1/2" to 2" to help you finish any job.
