1-1/4 in. 3-Piece 316 Stainless Steel Ball Valve
1-1/4 in. 3-Piece 316 Stainless Steel Ball Valve
The 1-1/4 in. 3-Piece 316 Stainless Steel Ball Valve (#949275) is a 1000 PSI WOG quarter-turn valve built for corrosive, high-pressure fluid service where brass or PVC won't hold up. Its 3-piece body unbolts for in-line cleaning, repacking, or seat replacement without removing the valve from the pipe, and the 316 stainless construction with PTFE seats and seals makes it a standard choice for chemical processing, oil & gas, steam, and water lines.
