Overview
The Midland Industries 941165LF is a 1 in. lead-free, full-port brass ball valve with Sweat x Sweat (copper solder) ends, CSA approved for potable-water and general service. Its lead-free forged brass body, stainless steel ball, and PTFE seats deliver bubble-tight quarter-turn shutoff at up to 600 PSI WOG across a wide -40 to 365 °F range. Because it is lead-free, it is suitable for drinking-water lines as well as hydronic, and general plumbing service.
