SharkBite 12 Inch (38 Inch OD) Expansion Straight Stop Valve for PEXA Tubing

Compatible with PEX-A tubing only and suitable for domestic hot and cold water service, burial installations including concrete, and radiant heating systems

Constructed from lead-free DZR brass for corrosion resistance and long service life, while PEX-A's elastic memory helps prevent kinking and strengthens the connection over time

Quick to install—use an approved PEX expansion tool to expand the tubing, insert the valve with the expansion ring, and allow the tubing to contract for a secure seal without solder or bonding.
