The T-1960NL no lead ball valve features a cold expansion PEX end, a bottom-loaded, blowout-proof stem design with dual-seal PTFE packing and stem seats to assure a positive seal. The valve body is made of DZR forged brass, which resists corrosion from exposure to various water conditions, while the self-cleaning ball is made from stainless steel. This press by PEX ball valve is compatible with both residential and commercial PE-RT and PEX plumbing systems.
