The SharkBite PEX Barb Reducing Coupling is made of lead-free DZR brass and provides an easy-to-install, cost-effective solution for connecting to PEX tubing. These fittings enable you to reduce the pipe size with a single fitting. The SharkBite PEX Barb fittings are compatible with potable water distribution and hydronic heating applications.
