About Brass PEX A Fittings

Brass PEX A fittings are a trusted solution for professional plumbers and DIYers who need strong, leak-free connections for residential, commercial, and radiant heating systems. Designed for use with PEX-A tubing, these fittings utilize the PEX expansion connection method, ensuring a reliable and secure fit that can withstand high temperature and pressure conditions. At PlumbingSell, our fittings are made from lead-free brass and meet ASTM F1960 standards as well as being approved for potable water applications.
